EDP - Experimental Digital Photography

I’ve been testing the Lensbaby Composer. The other day I went out with my Canon 350D converted for infrared (internal Hoya R-72 filter equivalent) and the Composer with the twin element glass lens. Here is one of the images: You can see others over on Digital ImageMaker World.

Hotspots on IR images are central overexposed areas. They seem to occur more on unconverted cameras than converted ones and only with some lenses. I’ve been working on a theory for some time that at least part of this issue is caused by light leaking through the viewfinder during the usually long exposures with unconverted [...]

As part of my testing of the Sigma 4.5mm F2.8 EX DC CIRCULAR FISHEYE HSM lens I went out with my Canon 350D that has been converted for infrared shooting. I was curious to see how the lens would perform in IR. But in the previous attempt at this article I got caught by my [...]

Lately I have been doing a lot of long exposure photography, both digital infrared and visible light. In the process of doing this work I have had shots that have been spoilt by flares, fogging and other artifacts. It turns out that these effects were cause because I did not have my eye blocking the [...]

Today I wandered outside and offset against a pure blue sky was skywriting being done. Now I could have just looked at it and gone back inside, but I naturally grabbed a camera instead. The camera I grabbed was my 350D that was converted for infrared photography and my 100-400 f5.6 IS L-series lens. The [...]

We often have expectations of what we can and cannot photograph. Usually these expectations are not only completely wrong but they also hold us back in various ways. I had this made clear to me last week. Last week we got away to the family beach out for a bit of R&R, which was desperately [...]

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:

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.

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 [...]
