Backtober

I recently listened to a one of Brooks Jensen's "Here's a Thought" short daily podcasts called backtober  Its about how he uses October each year to thoroughly review his digital back up and archives. He might be a bit obsessive, replacing any spinning hard drive older than 3 years, never less it has made me realize I need to totally re-evaluate my situation.

I have not found a good solution to replacing my little NAS unit. So automatic daily backups are not being made anymore!

  1. Most of my archiving is now on external (spinning disk) hard drives, and unfortunately, I have experienced 4 of these drives crashing in the past decade. There were duplicates of these so I didn't actually lose anything, Duplicates were on another hard drive (ie same format/technology)
  2. I do have archives up to 2010 on CD & DVD, They take up lots of space and I haven't touched them in years.
  3. I have a fairly complete "extra" archive on a larger old hard disk that I can connect into my "air gapped" linux archive. When recently accessed one of these older disks started reporting errors (and will have to be replaced, but I'm out of old computer drives!)
  4. I haven't evaluated the FreeNAS software yet!
It's October so I need to get onto these now, I like the idea of a full review yearly rather than my irregular monthly attentions (which has been overlooked a few times this year anyway).

David Hockney’s thoughts on the Art of Seeing

Those coming to the next Sketch Crawl, Sunday 18th November (there is still time to register at eventbrite) might like to view this BBC documentary which covers much of David Hockneys views on photography and the important Art of Seeing. The documentary does run for almost an hour and mainly covers Hockney’s revised inspirations from landscapes and lead up to Hockney’s Bigger Picture series of landscapes. The PhotoWalk/SketchCrawl is based around many of the same issues. So this You Tube is not only a very interesting in itself, it is also great context for the walk.


The harder to look the more you see.

Thanks for waiting ….

New glasses have bought a new clearer vision

Its been a long time since I last posted in here, and there are many small contributions as to why. It was never my intent to stop, just circumstance that discourage or  distracted me. Perhaps now is a good time to get back into the saddle because I see so much that is an emperors new clothes bubble surround discussions of photography related issues on-line. Lots of hype but the more I look it is just more of the same, a lot more… copycat more… more sameness… same voice… same message… even same composition & colours… on and on more…

Then there the whole issue of what life is like aside social media clouds. Actually its pretty good, even when you don’t know/realize you have been ghost banned, or algorithmically ignored.

So there no time like to present to take a deep breath and focus on the idea of being an independent voice and following my original aim of just investigation and writing about things related to digital photography and importantly not necessarily trying to follow the crowd.

Making Softer more Intelligent Filters

I have a long (aka deep) interest in the application of AI (artificially intelligent) techniques going back to the 1970s, it even survived the so called “AI Winter” of the late 90’s and 2000’s. It no surprise that I have been interested in the fairly recent Deep Dream applications to recognise style and transfer it to photographs. I have even, although slowly, warmed to “filters” that perform the magic of image enhancement (a lot of the early auto-fix buttons where and still are only half baked)

Trying to keep abreast of developments (and there a lot and they are fast), I noticed a very interesting presentation by Michaël Gharbi, a MIT researcher and also a keen photographer, at this years SIGGRAPH conference.

With this or similar apps I think you can expect smartphone technology to rival current expensive SLRs within the next couple of phone generations. However I think an intelligent camera just got a lot closer and  Michael has also been working on that also.

Back to the Future II

Having some fun with Pixlr on my phone
flickr have modified their snipet of html code when sharing an image to include a little java script that puts a hearder on the image to make it clear it came from flickr, the person's account it is taken from (me) and also shows a little watermark/overlay of the licence condition for sharing on the image.

A decade older, ..but any wiser

imageThis blog turns ten years old today. It began with a simple enough objective, Exploring the Creative Potential of Digital Technology and it is still pretty much wandering around the same themes. If you want to spend a bit of time looking around try the label cloud down on the right or type a topic that interests you into the search box. You won’t find any specific camera reviews, as originally promised, but you may find a lot about ways to use them along the way. Looking at my blog stats, I have improved views from around 1000 a month, when I set up the counter in 2005, to over 2000 now (see graph below). The blips in 2012 to the peak in 2013 were due to link spammers, so I probably need to knock off around 2000-3000 page views from the total. Still 80K is a decent number, not spectacularly popular (or worse viral success) but encouraging to continue all the same.

I suspect googles view numbers are very rubbery

So my advice is still the same get a camera, especially one you are happy to use (anything from a smartphone, Mirrorless up to a DSLR, they are all good these days) and learn how to use it. I hope the collection of ideas over the last decade helps you see some of the Magic of Digital Photography.

Onwards into the unknown …and more to learn and share as I go

PhotoProject :: Rethinking Digital Photography for Artist

A sketch photgraphed "in situ"There seems to be an even bigger gulf developing between traditional artist, (particularly painters) and photographers.Of course there are numerous exceptions and some contemporary artist have focused on photo realistic art as their special genre. Illustrators are also split with many fully embracing computer graphics with a few still promoting the idea of hand drawn as better. The explosion of “artistic” filters on phone apps and some better known photo software packages has however seemed to aggravate a raw nerve with traditional artists. I’m more perplexed, because I realise that photography and more specifically digital photography is a really great tool for any artist. I don;t mean painting from a photo. I actually think that is a bad move and seldom do it myself. As well as having amassed a large collection of digital photos I have dozens of sketch books, which are usually my first call for reference to any painting. Once you get into sketching it is actually a very pleasurable way to get to know an area or scene. Making a few sketches will in fact lead you to a more critical focus on what you actually photograph. A lot of art is about seeing, seeing the important features and perhaps leaving out the un-important clutter that does not convey the essence of the subject. Painting from a photo tends to promote a slavish focus on details,details that usually look boring and perhaps send a signal of inadequate observation, Whereas a few salient features captured in some “en plein air” sketches are more likely to character of the subject.
Having suggested sketching in the field may be more desirable, there is definitely a place to keep a series of photos of the details of some aspects. Here digital photography is a real winner because there is little cost in taking many photos, to assist as an “aide-mémorie” the downside for anyone artistic is probably managing all these reference images. Hopefully I’ll write more about this later.
A really important aspect not to forget when collecting reference photos is to remember to document your work. Photos of your work in situ (as the photo above) or you creating the art work may become very important in proving the provenance of your work.
Our eyes actually see differently to a camera lens. We have a much greater dynamic range of tones and colours we can perceive that even the most expensive cameras. Most of us have a much broader field of view than typical camera lenses. Whilst a wide angle can do this seeing around corners trick it usually distorted the image and verticals tend to become curved at the edge of the image. This is really most obvious in the traditional “landscape” view. You will never see curved verticals in an “old master” landscape. Perhaps this may relate to a slavish following of the rules of perspective and vanishing points. However a photo does the reduction of three dimensional space onto a flat two dimensional plan automatically. This is a nice way to avoid having to tackle the very technical perspective methods. A neat way around this is to employing David Hockney's solution of “joiners”, A series of conventional photos taken at slightly different orientations can be placed side by side to form a collage. If you step back the “perspective” is closer to what you see when you are there looking at the scene."Joiner" style collageMy view is that digital photography is a perfect tool to help an artist learn to better interpret the visual world. It is not a substitute for seeing but it is certainly an aide to making better and lasting observations. These are only just a few important issues for any artist and I plan to cover more in upcoming post.
