to contrast and levels. The histograms are still even with no “combing.”
The image on the right is a copy of the fi rst image but converted to 8
bits before the exact same changes to contrast and levels were applied.
Notice the severe “combing” of the histograms, evidencing lost data
that will affect image quality, causing posterization and other “nasties.”
I rest my case.
If your image editor does not support 16-bit TIFF fi les, my advice
is to get a better image editor that does.
Shoot at Low ISO
Noise. If there is one subject you need to understand as a microstock
photographer, it’s noise. To minimize noise, shoot at low ISO.
Your camera’s ISO setting represents the sensitivity of the sensor
to light. The lower the ISO setting, the lower the sensitivity and,
