EDP - Experimental Digital Photography

A recent flight to Sydney to deliver some photography workshops at the Sydney Hilton had me sitting in a window seat. So I spent the flight happily shooting IR out the window.

Here is one of the resulting images:

To teach my 9 year old daughter how animation can be done, we set about creating the two short animations you can see here by taking many still images with Lauren’s camera with small changes made to the models for each one. We then put these together in Adobe Premier or iMovie and exported the movies.

We spend about two hours on this and it was a great way for my daughter to get some hands on movie making experience.

We had the official opening of the ‘A World of Photography’ exhibition on the 30th of November, from 7pm onwards. This was the second event that brought people into the exhibition, the first being a celebration of the accreditation of the new degree course the Australian Academy of Design.

My Canon 350D arrived back today from LDP in the states (www.MaxMax.com) who converted it for infrared photography by removing the IR blocking filter and replacing it with a 715nm IR filter.

Here is the latest test image. Shot with a 400D, 100ISO, 1/2 second exposure. A bee.

I am still getting what seems to be glar in the center of the image. I am looking at replacing the normal eyepiece with a photo one to see if this works better.

I’ve had requests to show the rig I have been experimenting with. So consider this a first pass at this.

I am using a Chinese made (I am looking at importing and selling them in Australia, as the price is GREAT) stereo binocular microscope that seems to have very good optics. It is a zoom model with a 1-4x objective pair and a 10x eyepiece pair, for a normal coverage of 10x to 40x. I can swap eyepieces for greater or lesser magnification. It has the trinocular head setup so that the camera mounts to a third, vertical eyepiece, also a 10x at present though I will likely swap this for a specialist photo eyepiece at some point.

Below is a picture of the whole rig followed by a closeup of the camera section

After careful focus setting for the camera eyepiece, so it is parfocal with the main eyepieces, I got the following result with my Canon 400D.

Below is the first image I got through my microscope, a 10-40x stereo binocular microscope.

It is a bit low contrast compared to the view through the microscope and not as sharp.

Ok, Voting is now closed.

I propose the following images as those having a vote score of over 2.5

All digital cameras us sensors which are sensitive to infrared light. Most recent digitals incorporate an IR blocking filter just in front of the sensor that blocks a lot of this light. However, it does not block all. Thus all digital cameras are capable of shooting in IR, just the exposure times can be quite long. This can, in fact, be an advantage for some types of photography, giving a beautiful ‘otherworld’ look as plants move in the breeze and blur, for example.
