Selling digital photos on microstock photography websites
There are an ever increasing number of websites which allow photographers, both amateur and professional, to sell stock photography images online with a minimum of fuss and hassle. This page chronicles my ongoing experiment with selling some of my own photos on some of these sites.
The GIMP doesn't seem to have a Maximum (or a Minimum) filter. Looking at a description of what the Maximum filter does, it seems like it shouldn't be hard to create a Maximum or Minimum filter for The GIMP using Script-Fu.. Two obvious implementations come to mind, one of them O(N*M2) where N is the number of pixels in the image and M is the radius given to the filter. The other obvious choice would be O(N log N), which might actually be a better way to do it.
While reading about soft focus, I came across a method for applying soft focus digitally. One of the steps involved was a motion blur. After some experimenting, I discovered that the GIMP motion blur moves the image from where it previously was, by one half the blur length. The examples in the article lead me to believe that photoshop leaves the image where it was, without shifting it over, which seems to me like the correct behavior.
I'm looking to modify the EXIF/IPTC meta information in a Canon RAW file (.CR2). In particular, I'm trying to add title, description (subject) and keywords tags to the file before uploading it to dreamstime. However, I do not want to change the last modified date stamp of the file.
I discovered that my LCD monitor (Dell E176FP) was way too bright, so I adjusted the gamma up by editing my xorg.conf file to add a Gamma line as described an article on linux.com. In fedora 7, the xgamma program is contained in the xorg-x11-server-utils package.
I took some photos yesterday that I'm looking at now, and several of them have camera shake at 1/100s. I was never extraordinary at shooting rifles, but I'm usually able to take pictures at around 1/50s or 1/60s without problems. I guess this means that I need to try and remember to stay conscious of my breathing and movement all the time when taking pictures, not just at extremely long hand-held exposure times.
