Experimenting with Ilford Delta ASA 3200 B&W Film

So it has been a long time since I’ve shot film… and it pretty much was always colour. Part of this was in prep for Burning Man. i.e. how to take a photo in the dark (and part was “hey, what cool tricks can I do”).

Reading up on film, I found Ilford Delta 3200 Professional as something that could be interesting to shoot with. I’d read a bit about it, checked out the flickr group and decided what the heck, it’s only money.

I grabbed my dad’s old Ricoh SLR and took some photos – trying to learn how this film responds, what I can and can’t do with it along with developing my own skills.

I got Michaels to develop and scan (hey, they do B&W processing in Melbourne in a reasonable time frame)… ignoring the advice of some that doing it yourself gets you best results (anyone for a Laundry/Brewery/Darkroom?)

While at Rrose, I took this shot which I quite like:

If you look at full size you see the wonderful graininess that is this film:

F1000023_crop1

But a simple GIMP Despeckle gets you:

F1000023_crop1_despeckle

(and a much smaller JPEG file size). But I do kinda like the speckle.

The amazing thing to note is that this was shot handheld with a not particularly fast lens and without any artificial light beyond what was at rrose at 9 or 10pm in August.

stringstream is completely useless (and why C++ should have a snprintf)

  1. It’s easy to screw up thread safety.
    If you’re trying to format something for output (e.g. leading zeros, only 1 decimal place or whatever… you know, format specifiers in printf) you are setting a property on the stream, not on what you’re converting. So if you have a thread running that sets a format, adds something to the stream, and then unsets the format, you cannot have another thread able to come in and do something to that stream. Look out for thread unsafe cout code.
  2. You cannot use streams for any text that may need to be translated.
    gettext is what everybody uses. You cannot get a page into the manual before it tells you that translators may want to change the order of what you’re printing. This goes directly against stringstream.
  3. You need another reason? Number 2 rules it out for so much handling it’s not funny.
