One reason for using a camera is the concept of an “aide mémoire”, but I always carry a sketchpad as well as a camera. I actually prefer “en plein air” painting and sketching to copying photos, but having said that it is always nice to have photographic reference material when completing any at work. So how do the camerphones images compare with my sketchbook. Is that even a fair comparison?
Using the viewfinder helps frame the image and set some boundaries of what I might put on the page. It helps convert the complex 2D world I see into the perspective of a 2D plane. Compared with my tonal pencil sketch above it does provide colour reference, yet there is a range of colour intensity between the photos. So as a painter, I feel that a camera phone will be a perfectly acceptable way to collect photo reference. One advantage of the DSLR is I can zoom in and get a bit more detail on a specific part of my subject. However I still believe a sketchbook is a much better way for an artist to really get a sense of the place.
As an interesting side note I have been trying out a few photographic apps for my android phone. I like the idea of being able to try out a free version, before having to buy the “Pro” version. One such app is called Camera Fun and it simply provides a set of in camera filters. I like this one called simply Sketch. There are lots of such filters in Photoshop and other photo packages and I have tended to avoid using them. Ok they are very gimmicky, but Camera Fun is immediate and fun

I must admit I still like geotagging with picasa and google earth, it is probably now a very clunky and old fashioned way to do it. Perhaps its the nostalgia of revisiting places I’ve already been! Anyway a new smartphone, a HTC wildfire, which is a special model for telstra and most importantly available for purchase (reasonably priced) without a contract (prepaid) meant I was now carrying a GPS everywhere I go at less than the cost of an average GPS unit.
So I figured it was time to try out some of the applications that automatically geotag your photos from a GPS wayfile. All roads quickly lead to Geotag Photos, who offer a number of programs and apps, including on-line, desktops apps (for Windows,Apple Mac and Unix) and smartphone apps (for Iphone & Android). They even have Lite (Free) versions which have reduced features on the phone apps. Specifically the Autolog Feature which will automatically log your position at regular intervals. The essence of the application is a merging of a wayfile (that traces your movements) and matches your photos by time and updates the location in your photo’s EXIF metadata..Sounds a bit complex but there are just 4 simple steps
|Synchronize the time and date on your camera & phone||Start recoding location on phone* and taking photos with your camera||Upload your trip** (the .gpx wayfile)||Geotag all the photos later with the desktop application and your wayfile and photo directory|
* I’m using the Lite version so I have to manually record the way points, by pressing the green map pin on the phone at the places I photograph.
** How you upload the file will depend on how you connect your phone to the computer. I found it was easiest to connect the android phone as if it was a USB drive and just copy the file into my photo directory on the PC.
All nice and easy so much so I’m giving the Lite version a really good try out, but already I’m thinking the pro version is a real photographer’s “must have”" tool for geotagging.
The Archibald price is Australia’s premiere portrait prize, most notable for controveries. This year the collection have travelled south to the Tawa Wara Museum of Art, near Healesville, within Victoria’s Yarra valley. So it was an easy decision to make a day of it and have a look at the original art work. The exhibition only has a week to go and if you haven’t been its well worth the trip. The Tara Warra Gallery itself is worthy of the visit,The gallery design was selected by a competition, with Allan Powell's elegant design the winner and it is set beautifully atop a hill surrounded by vineyards.
I should have realised when I took the Dandenong Creek panorama, which I was very disappointed with at the time and inspired the series of comparative posts, that poor resolution of that image was really a function of the camera’s own in-phone panoramic feature. I would have been much better off to take multiple overlapping cameraphone images and use autostitch (as I have done above)

Clearly at the macro level (Close Up) there is a massive difference in what a simple lensed camerephone and a DSLR with a specialist marco lens captures. Its probably not a fair comparison. Beginning with the exposure, the depth of field, and colour fidelity everything is better in the top row, yet you can still recognize what has been photographed by the phone.

Taking photos when its dark is not something many people try without the flash,but there is a magic world of low level light out there. You just need a tripod and the means to take a long exposure.
Well I didn’t have either my tripod or my magic little remote control trigger. I did have my camera and It does have that useful B (B for bulb) settings. which holds the shutter open all the time the shutter is held down (much easier with the remote control. There was a flat balcony rail at my vantage point, and I could use it to hold my camera firmly to it. So with a little bit of experimentation. At ISO 800 I just started by hold the shutter open for 10 seconds, too dark, 20 seconds. still dark and finally 30 seconds, just right! Then I tried to capture a night time panorama (see collage above). That didn’t really work so well, but the two end photos worked out well enough.
PS: Most point & shoot digital cameras will have a night scene mode, it may not let you control the length of the exposure but it will give you an extended exposure without setting off the flash.

The low sun of winter gives you a bit more opportunity to get down and get those stronger compositions from the silhouettes of trees. To create a little drama from the often routine bland and ordinary

Will this make a difference to those already using Picasa, or Blogger I hope not. We will just have to wait and see. The possibility of instant upload of photos and videos from phones & cameras has been mentioned in a few reviews. Sounds far fetched?
Maybe not, you take your photo or video and then there it is on the net automatically, ready to share.
Has it already been snared and ridiculed, before you realize what has happened?
BE WARNED there are already scammers offering fake Google+ invites (and phishing your details in the process) or charging for fictitious invites that aren’t real anyway and the invites are free (see link above), You just have to get on the list and be patient
