UV tube vs led: a quick comparison

I already announced in my previous journal entry, but it arrived even quicker than I anticipated: the 300W UV led source I ordered from China. Although it was also laundry-and-house-cleaning day, I couldn’t resist giving it a go. And in particular, seeing how it would pitch against the bank of UV tubes I’ve had around for years. Here are my expectations when I ordered it: (1) higher total luminous flux, so shorter exposures, (2) better collimation, so less bleed and better detail rendering. How does it pan out, you think?

Corn print

Yesterday I made a print that I’m very pleased with. The negative just about perfectly suited my current carbon transfer skillset and as a result, the very first print of the negative is about as good as it’s going to get. Alright, there’s a few minor issues that need ironing out, but the image is quite presentable, I think. Here it is:

Relieved

Today, I decided to straighten a print I made yesterday from the series on corn I’ve been working on. When rewetting the print for taping it down, I couldn’t help but noticing the relief on the wet print, which stands out particularly nicely on this one. Look:

Making black, making white

There are many things to like about carbon transfer printing (and at least as many to dislike about it…). One of them is that essentially, you’re making the black and the white separately and then marry them when making the actual transfer. The black is the tissue, the white is the final support. Combined, they make for a continuous tone image. Pretty neat if you consider that they start out as pure black and pure white!

PVC development tubes for sheet film

Warning: again a total lack of originality on my part. The upshot is that apparently I don’t suffer too badly from the not invented here syndrome because I proudly ~~stole~~ reproduced this idea from Tim Layton whom in turn was inspired by Phil Davis and his “Beyond The Zone System” approach. The whole idea is essentially just a hollow tube with two end caps in which you put a single sheet of film, fill ‘er up with developer and agitate in whichever way you fancy. This could be a fancy water bath agitator like in the official BTZS approach, or, as in my case, simply turning the tube over and over like a regular daylight tank, or rolling it on a counter top.

Beginner’s luck

Well, not an appropriate title, that’s a good start… this post is about carbon transfer printing, which is something I did quite a bit of a few years ago. I don’t think I even had a large format camera back then, so I just used digital negatives instead. And grew very tired of it, very quickly. Well, after making a couple of hundreds of prints (mind-numbingly boring calibration charts as well), that is.

New horizons

I created the main page of koraks.nl back in….2005, probably. That’s a long time ago! For a few years, I fairly diligently updated the galleries and from time to time, I wrote something about how I did photography. A lot has changed since then. Panta rhei!
