Some software for photographic freelancers:
FotoBiz looks pretty comprehensive, with a FotoQuote stock pricing module. It's written in FileMaker and is extensible. $229.
An index of software for photographers over at stockphoto.net. Not a very focused list, but maybe worth a look if you can't find anything else.
I've been trying to find some relatively easy software solutions to the problem of tracking photography submissions to various publishers. There are a bunch of options for freelance writers, but none I can find for photographers.
I've recently been learning a lot about the L*a*b (or Lab) color space, for image manipulation.
To see why, here's a simple experiment you can do: Open up an image in Photoshop and convert it from RGB mode to Lab Color mode. Add a Curves effect layer (or just edit the curve) and tweak the a and b channels. Choke them down so that a 90% input equals a 100% output, and a 10% input equals a 0% output.
Now compare the original image to the tweak. You can't do this by simply turning up the saturation, either...
So here's some stuff dealing with L*a*b color. More to come on this topic, for sure.
Norman Koren walks you through the basics.
I'm a sucker for a DIY project:
And to replace the CS-205:
The latter project has the benefit of being useful for non-Pentax cameras, as well.
I'd like to find a kit for making a timer device. Anyone know of any?
