2/11/05 - Another Experiment

ds20040813_0029abwF dds tri-x 400.jpg

It was suggested that I add some "grain" to my b&w images to simulate actual b&w file. So, I took another of my tiresome series of SP's, cropped it, and applied the following procedures (on four copies of the basic (color) image.

- Overlay layer of 50% grey (no noise added) as reference
- Tri-X 200 Action
- Tri-X 400 Action
- Tri-X 800 Action

This is the Tri-X 400 version. Note that I should have spent a little time on the original to soften the hot spots (and remove a few facial blemishes -- why do only women get to wear makeup?) I realize there are a gazillion addional ways of doing the grain addition and the b&w conversion, but I didn't have a gazillion hours to try them all -- plus, my hands are getting stiff. Not sure where I got the actions (probably some place pointed to by another pbaser), but they're very simple: Noise, Brightness/Contrast, Channel Mixer -- each with diffent parameters on the image adjustments.

The following image is a composite of the four images for direct comparison.




This is the SP I had initially posted for today.

Good work, Dennis. One can not notice the grain in the clear highlighted spots of such a picture. But, when you look at the grey shades of the picture and especialy the DOF part of the shot, you can see right away how much more you get out of such a shot. Here the dof area looks nice and contratsed while on a simple digital b&w this area is seen as a simple dark grey surface. Try this with other shots and you will see the difference. Note that this effect is much more present at a large size view of a photo.

I know nothing of grain, but this looks nice.
