When more becomes too many

As I walked through the forest I just took almost exclusively bracketed sets of images. Not only for a single scene but also for every image in a panoramics series, the number of images quickly multiplies.

I already take Raw & Jpeg, then 3 brackets means 6 images when I press the shutter. Next I might  take 5 overlapping photos to cover the full range of the very tall trees. And I’m up to 30 images just to get. A single final photo.  I took around 20 such multi-image panoramas and wow over 600 photos on my hard drive. 30 images to make just 1 vertarama

Just looking through that number of images becomes a challenge. It makes a couple of minutes (mainly waiting) to create the HDR image (using default preset/setting). Longer if I want to tweak any settings.Intermediate step of producing individual HDR tonemapped imagesThis steps also creates another larger .Tiff file (I’m creating 16bit tiffs to get maximum dynamic range and colour info). Next the autostitch can be as fast as a few minutes for a small preview but that quickly becomes about 20minutes (again mostly waiting) if I want a large (almost full size, ie as large as assembling to component images). Even though my little HP spectre only has limited disc capacity and slightly lower speed (i5 versus i7 processor) than my desktop. memeory is the same and the HP has an SSD drive which makes everything, even lightroom, look snappier. Suddenly I realise I’m spending half and hour on each separate HDR/panorama. That’s going to be 10 hours if I want to process all images. Worst the photos and sub-stages would take up about 17 gigabytes! This is turning into a nightmare.

Ok that’s just too much. So I’ve opted to do some preview stitching to a small image size (1400 pixels wide) from the EV=0 exposures to judge the desirability to go to more complete processing. Cutting the task down to just 4 big images at the moment. The first image below I spent over half an hour setting is not one of those I wanted to keep! Such is life.

Sketching Kit Four :: Making a new drawing board

While I was in Tassy I found the blue folio containing my art gear was a bit awkward to always carry around. weight wise it was fine it just always required being held in one hand (eg I had o put it down to take a photo etc) and it was a little on the largish side anyway. So I started leaving it behind and only sketching with what was in my camera bag (which was probably fine). But leaving my better art gear unused seemed a waste, and while passing the Kathmandu Shop in Salamanca place I decide to ask what they had as a temporary backpack to carry the artgear. After being shown a few expensive unsuitables I was eventually shown the 15L pocket pack (it rolls up into it own little pocket, and is designed to take up little room or weight in your luggage but provide a suitable “day” pack if required) It looked sturdy enough and was about the right size and price, I immediately transferred all my gear, including my Derwent Inktense pencils & blocks (a new favourite). Well, except no drawing board or individual sheets of watercolour paper, which where too large to fit. Happy ending, I carried my art gear everywhere after that.

15L Pocket Pack & Contents

I really like the idea of a backpack, so I resolved to make a slightly smaller drawing board to fit in the pack. It was simple to make from particle board. The shape is a little tapered and rounded at the top so it is easy to slide into the pack. Unfortunately this means half sheets are too big and I will have to settle for quarter sheets of watercolour paper! The board is ample sized for A4 sheets or an A4 sketch book held down with clips or a couple of rubber bands. I have also painted one side white and the other a darker gray. I have also been recently experimenting with notan/tonal value cards, so I figured I’d add a simple 5 step gray scale tone checker. Getting the tonnes reasonably accurate with acrylic paint was a bit harder than I expected (since acrylic paints notoriously dry darker than it looks when first mixed) so a bit of trial and error was required. The greyscale is conveniently always at the on the top or right hand side of my drawing board, so it will be easy hold the board out and check tones. The final embellishment was to drill a small hole as a colour checker. By positioning the hole over an area of colour it is isolated from the surrounding colours, and tones, and easy to compare with your work on the drawing board.

I’m not certain who much use I’ll get out of these tone and colour checking tools, but they look neat and they will always be easy to access and ready to use

More time doing, no time for blogging

Photo by my wifeMy endless summer project trip to Tassy was great, did lots, saw lots and got plenty of inspiration (not necessarily a lot of sunshine). C’est La vie.

My instagram @oz_endless_summer has just some of the of the stuff.

In the end it was better to do than blog about it, right?

Suddenly Instagram is beginning to look like my sketch books

I’m the first to admit I haven’t figured out the appeal of Instagram, other than its easy of use and a way fast disposal of images (short viewing life and soon forgotten). Then again I have had fun in the grid view with mosaicked images and I’m still posting in threes, BUT….

What the? I’m still posting to my art project specific account @oz_endless_summer and the posts are starting to go all over the place, a bit of that here and something 2017-02-07-14-36-46different there and then back to something else. This is starting to look like the contents of any of my sketchbooks. The worry is, the more I blunder around, the more likes pop up and the followers while going up and down are at least growing. Making all this harder to understand.

What is worse I do already have an on-line sketchbook which has gone from “My Daily Sketch” (it was last years commitment that didn’t last) to “My Occasional Sketches” (aka myscratchings.tumblr.com) on tumblr. Yes I post much the same stuff there still as well. Tumblr being in my opinion a much better platform, specifically I can control the links and syndication. Importantly it is not a walled garden like instagram. However tumblr is quiet (not as dead quiet as Google+ has become) but not many see my stuff and few like or comment. I’d convinced myself no one was interested in my works in progress and idea development. I just didn’t know where and who. So it looks like it time to toast Sketchbook Instagram.

Such is life

More Observations on Photographing Art

I have previously hinted that photographing art might be superior to using a flatbed scanner (well at least the ones built into most multifunction printers). Well I now have a strong case to confirm this suspicion. I have been working on a series of mixed media painting I’ve called the “Summer People” for my larger Endless Summer Project. Whilst I have left the people blank (they are only temporary visitors to the beach) I decided They need to have coloured clothes, and fluro colours are still popular with the summer people. However when I scanned these I was amazed… The fluro colours were flat and very pale. I’ve been looking for an explanation about the direction of light or quality of the light source but I have none to explain this observation. Taking a Photograph the same painting (images on the right below) in daylight the colours are much truer including the non-fluro ones.
Scanned on flatbed scanner Photographed Art WorkScanned on flatbed scanner Photographed Art Work
My Studio set up with the copystandThe main advantage of a flat bed scanner is it (in theory) avoids dimensional distortion, such as non paralleled edges produced when the camera is tilted. I did make an old fashion copy stand out of an old enlarger mounting and can connect my canon camera to my studio computer in tethered remote live view mode (see below). The image is upside down here because of the way the camera is mounted on the stand and because the painting is facing me. I could fix this by putting the painting upside down on the table top or just as easy fix in while post processing in lightroom, I can also focus and control exposure from the computer and once I have every thing set up just slide the canvases one at a time check focus and exposure and click. Its actually faster than loading a scanner closing the cover and click then waiting for the scan, Looking at the preview screen doing adjustments (like rotation) and loading the next canvas…
Remote Live View screen
I also need to be careful not to use a zoomed in or wide angle lens, which can cause barreling (curved rather than straight edges to the canvas) A focal length between 50 and 70mm on my crop sensor canon avoids distortion so I have to adjust the camera height up of down to best frame the picture. In this case I lifted the copy stand onto an adjacent counter top.


Another issue with using a camera, is there is less control of the light source and a colour cast can be common. I prefer to only photograph art (and in fact only paint) in daylight. Not direct sunlight but a strong diffuse light such as a window. Even so the colour of the room and its contents will affect the light so it is also wise to consider white balance. By taking RAW format this can easily and well adjusted in post processing. I therefore take a calibration photo using just a commercial colour wheel and one of my notan (greyscale) cards.
Original Photo of Test ChartsAuto White Balance in Lightroom
In this case the test is a little “warm” but may be acceptable. I use lightroom and it has a very decent Auto White Balance, in this case it is colder and more clinical, but better colours and grey scale. You can manually adjust the degree of correction but I’m happy to go with the auto correction. Further lightroom lets to refine the adjustments on one image and then copy that to all others captured at the same time.

I prefer to leave room on the margin to allow for trimming later and to individually crop and rotate each picture (again its easy in lightroom) but if you are copying a lot of items the same you could put masking tape as location makers and then fill the frame and have the cropping automated as well.
I am pleased. Using my DSLR canon camera, mounted on my homemade copy stand and tethered to my studio computer, I can reliably and quickly get superior copies to those achieved with a flat bed scanner. By also taking a calibration shot, and photographing in RAW format and then post processing in lightroom, I can also automated white balance and minor exposure adjustments across a whole series of images. Giving me much better and consistent set of images of my art to post on-line.

Sketching Kit Three :: The Original (Blue Folio)

This is actually my long standing sketching kit, having undergone many changes yet remaining much the same.My trusty old folding palette It is based around my small portable folding palette preloaded with colours, I experimented with the layout of colours but reached the current set up a few years ago now.  Top Row are warm colours, and from left to right, Cotman Dioxazine Violet, W&N Alizarin Crimson, W&N Cadmiun Red, Cotman Indian Red, Cotman Yellow Ochre, W&N Lemon Yellow, W&N Cadmium Yellow, Cotman Gambage Hue, Cotman Raw Sienna, W&N Burnt Umber. Bottom row is the cooler colours again from left to right,  Cotman Chinese White, Cotman Lamp Black, W&N Paynes Gray, Cotman Sap Green, W&N Viridian, W&N Phthalo Turquoise, W&N Phthalo Sapphire, W&N Cerulean Blue,W&N Cobalt Blue, W&N French Ultramarine  These started out as mainly Windsor and Newton Artist’ Watercolours (in tubes & expensive) but this has given way to a few Cotman colours (also in tubes but affordable). Where transparency is not a characteristic of the colour I desire, such as in earthy tones like yellow ochre, I suspect the Cotman’s are just as good. For small/quick sketches the Windsor and Newton watercolours may be overkill anyway but they come into their own on good quality watercolour paper and larger works. I have been known to put this folding palette in my camera bag with a couple of brushes a small sketch book but kits one & two living permanently in the camera bags have made that unlikely now.
My most comprehensive field Sketching Kit
I carry the paints and media in a blue canvas folio. It holds my field drawing board, which has a appropriate sized nut glued on the underside so I can amount it on my camera tripod if a portable easel is required, but normally using it on my knee is fine. This board is just a bit larger than a quarter sheet of watercolour paper and I usually carry 4-8 sheets held in place for transport with rubber bands. I often have a sketch block or watercolour pad included, although I now like the idea of having a few post card sized pieces of watercolour paper as well. I sometimes finish a sketch, write a message on the back and post it (my post cards from Canada were popular with my family). I can also fit a full sized plastic palette and my canvas roll of my watercolour brushes. Its a pretty light setup and the canvas handles make this easy to carry. I usually also carry a full set of watercolour tubes in my luggage in a largish plastic screw top jar which can double as a water jar when needed, I seldom take these out sketching. The orange flagging tape is to make the kit easier to find in the field, whilst the blue is strong it can disappear when left in the shade, the orange tape against the blue is hard to miss.
I also still have my foldout studio always ready when I want to create a decent work place on the go. However this blue bag kit is what I will be taking in my luggage for most of my Endless Summer project trips.

Sketching Kit Two (Think Tank Bag)

1-_IGP2233Despite having a fairl hefty Pentax K20, typically with a weighty Tamrom 18-200 zoom and polarizing filter, I actually bought a Think Tank Mirroless Mover 30i before the trip to Canada last year. Despite being designed for a mirrorless system but it holds my camera and my sigma 70-300 zoom plus a few small accessories, battery extra cards etc. It also has a slot at the back probably designed to take an ipad mini but it is just fine for an A5 sketch block or A5 Visual diary, so I also slipped in an old tin of Neocolour II water-soluble crayons. I like using them, they have good intense colours once activated by water and I’ve had these for several years but haven’t been able to fine a local supplier so I tend to use then on and off. The discovery of water brushes means I don’t have to carry water but I do also pack in a couple of brushes, pencils and/or pens. All this takes up very little room and almost no extra weight (depends on thickness and paper weight of the sketch book mainly) so I can leave it in my camera bag at all times.

Sketching Kit One (Canon Camera Bag)

I’m experimenting with what is the minimum amount of sketching gear I need. Specifically what can fit in my camera bag along with mu normal camera gear, The first kit consists of an A7 sketch book and the very compact little Cotman’s Sketchers’ Pocket Box produced by Windsor & Newton, a water brush, a soft pencil, a dagger brush and a jell ink pen. I also hand carry an A5 general purpose sketch book (shown below)which slots nicely into a pocket on my new beach chair.Sketching Kit One with A5 sketch pad
A7 sketch pad is good for small compositional sketchesThe original benefit of the water brush is it has its own reservoir for water, so I don’t need to carry a wash jar and water. However the water brush is really cool you can easily control how much water is required by squeezing on the barrel. I did find a need somewhere to blot off the pigment when I want to change colours, the back of my wrist was fine at first but I think I’ll start putting a little folder kitchen paper in the sketch box in future. The little A7 sketch book is really only good for simple sketches particularly a quick composition or notan sketch.
Trying out the Cotman ColoursThe watercolour is in half pan size and the colours really intense but the dilute down to wonderful translucent washes. I have already added a turquoise, in place of Chinese white, but I find the two greens (viridian and hookers green in the set a bit intense, and might swap one out for a mauve, indigo or even payne’s grey. Time will tell. This is a really wonderful little set and fits snuggly in the front of the standard canon camera bag.
Final I also have my camera, may canon camera is my designated beach camera at the moment, so I can always take a few photos as reference.
Photo - sailing inverloch
I Like my watercolour wash sketch a lot even though I didn’t get time to let it dry enough to finish off on the beach. I then remembered having some good results using my compositional sketch as the training style with google deep dream generator and dreamscope app so I put a few other photo/sketches through the style filter. The results are pretty amazing.

Post Beach Cleanup

1-2017-01-31_11-10-03_HDRI realise that painting and photographing an endless summer will involve a number of beach visit. Fine sand being the natural enemy of precision camera components, and particular hard on SLR camera. Thus I have designated my canon camera for beach duty. Not that I haven’t used my Pentax many times already at the beach. However the Canon camera bag is smaller and seems a tighter so less likely to fill with sand (or so I thought). after a few days of such beach duty The camera and bag had fine sand everywhere, so before I looked at dust on the inside I got out my hairdryer (I have one to dry watercolours) and gave it a good cool blast and use a soft watercolour wash brush to dust as I went. I also emptied the camera bag, took it outside, turned it upside down and gave it a long blast with the hair drier. That fine sand is pesky stuff but it does respond to a strong air flow.

HOWEVER SET THE HAIR DRYER TO COOL!  be careful not to overheat the camera or components

The all important question remains. What about dust on the sensor? Well I didn’t change lenses at the beach and the sensor appears to have no more dust than usual.

The Notan Strip on my Hat

So why would I paint a set of Notan inspired grey shades onto my hat?_IGP1982_HDR

I’ve noticed that when I use a polarizing filter in the strong harsh light, The filter is definitely adding a warming effect into the colours and infact acting a little like a 2 or 3 stop neural density, My experience over the last couple of weeks and particularly a sunburnt nose saw me purchase a basic white floppy hat. Not a high fashion item but very useful on a hot sunny day. Then I realised that if a drop the hat to the ground and included it in at least one exposure I had a perfect reference tool to fiddle with the white balance in post processing, Adding a series of Notan reference tones hopefully will mean I don’t have to keep using my reference card, they are there on my hat.

The acrylic paints I used have, as usual darken once the dried so I may have to repaint the tones again a little lighter

Festival of Sails & looking for Summer

 

_MG_0417-EditI went down to Green Point to watch the festival of sails making  their way down to Geelong. But the light on the sails didn’t last long. _MG_0442-Edit-2_IGP1961A squall soon raced across the bay and it began to rain, not exactly summer. Oh well home again…

Latter in the afternoon The afternoon bought plenty of sunshine and clear skies and I noticed that the back patio had a real 1960s Californian Hockney feel, aka endless sunshine. So I took a few sets of bracketed images from slightly different positions, with Hockney’s idea of “reverse perspective” in mind.

A Pleasant Surprise

Lower Tarwin Evening I was out taking some photos of hay bales across the road (in HDR) but the sun was getting a bit low, so I walked up onto the levee and took a series of Bracketed photos that encompassed a wide panorama out towards the river mouth. I didn't bother processing the HDR that night because I was more interested in the hay bales (wrongly). When I finally got around to creating the HDR series I was taken with the delicacies of the low angle light.

PhotoProject :: Art Of Photography :: Assignment 2 :: Low Angle

Whilst I am primarily doing this project in a sketchbook, and context on tumblr, I decided to present the outcomes here as well.

_IGP1337_HDR_IGP1331_HDR_IGP1364_HDR_1

Originally I had planned to include the above photos, but my printer ran out of ink at the weekend and I decided to handcolour some laser printer prints using washes of Derwent Inktense blocks (water soluble crayons with intense ink colours).

I quiet like the results. The colours are muted and simplified, bringing the results into a more handcrafted feel. Perhaps the red was the least successful. You can learn more about the Art of Photography and specifically this assignment from the You Tube video below

Right Place, Right Time

I had  parked beside the Oakliegh Football ground on my way to a show at the Caravan Club, “Feelin’ Groovy” The Simon & Garfunkel Project  (its a Jazz Influenced band with two female singets, playing the folk/rock and harmonies of Simon & Garfunkle, and it really works. There is a another performance coming up at the National Theatre.) Anyway I have digressed I was a little late but as I looked up I saw the last rays fo sunlight break through the clouds and climb into the sky. I had to turn back and get my camera and take a bracketed set of photos to make this HDR image. There are times when You need to realize you are at the right place, right time.

By coincidence the theme the week on Photo Friday is silence.  (The Sounds of Silence)

Enough already with the Notifications

I had planned to use instagram and twitter via my phone during the periods when I was travelling for my Endless Summer project. However leaving data on and getting hundreds of notifications from instagram and less from twitter I quickly discovered that I had used over 60% of my monthly data allowance in just 4 days! Wow, I seemed to be getting notification even though the apps where not running on the phone, The twitter beeps and tweets where the most annoying since they where not related to my posts or even things that would interest me anyway. they were just trying to grab my attention. The deeper worry is that in all this activity I feel like I am just yelling into the wind, not joining a “conversation”. So the solution is simple just log out of Instagram and twitter and turn off data. Silence … …

My cartoon creation Alvin people was actually one of the earliest Australian Twitter accounts, predominantly to link to and later post cartoons. My cartooning is having an extended holiday, but I decide to consult Alvin as he would probably know what to do. He readily admits he hasn't posted in years and after going through the forgotten password dance to resurect his account he managed to set off a cacophony of chimes, beeps, tingings, chirps and other electronic sounds. Clearly he could not find how to turn off the notifications either.alvin notifications

He did find you can unsubscribe from twitter using a link on the bottom of the web site

Beautiful Evening Light

Went for a walk in Jells Park, to the Oaks Picnic Ground and the night was warm and balmy but the light wonderful. I made a few HDR bracketed sets but I like this one the best.

The Summer People Series begins

_MG_0048-EditAfter mucking around with the frame within a frame idea. I remembered a painted I did almost a decade ago, of beach people in outline with a loosely framed sections of a stylized beach (it is about 900 by 900cm square). I still like it and despite a couple of decent offers have not sold it.

So I decided to update the idea of a smaller instargam-ish fashion image (only 20cm by 20cm) and just paint the background of the sky, surf and sand in bright acrylic colours in a beach sand inspired frame. Once I started I released I should also paint the brightly coloured (or not beachwear) but leave the people blank (representing they are only short term summer visitors to the beach). I also wanted strong outline so I found some Indian ink and cut some reed pens.
