Thanks for the help everyone! I'll bring back the details in the feathers. KmH...Do you mean the curves? I use lightroom... What is clipping mode?
I also have a Mac... is it already calibrated or do I need to calibrate it? Is there a difference in calibrating? Sorry for all the questions!
Nope, I don't mean Curves. Yes, all computer displays need to be calibrated if you hope to get prints made that look something like they do on your monitor. It is just part of what is known as "a color-managed workflow".
In the Lightroom Develope module, under the "Basic" tab there is a slider named "Exposure" and another named "Blacks".
I don't use Lightroom, but I do use ACR, which is actually the same thing Lightroom uses and ACR works the same way. ACR has been around quite a bit longer than Lightroom.
If you hold down the Alt key (or it's Mac equivelent) while your cursor is on the Exposure slider it invokes 'clipping mode' and the screen will go completely, or mostly, completely black.
If there is any other color than black on the screen, those areas are being clipped (to bright/blown out/no image detail left). If there is only red (or only blue, or only green) showing in the black screen, only the red (or only blue, or only green), channel is being clipped. If the area is magenta both the red and blue channels are being clipped, etc (red+green=yellow, green+blue=cyan). If the area is white, all 3 color channels are being clipped.
The Blacks slider works the same but the screen goes all white but there are some colored areas (to dark/blocked/no image detail left), instead of all black.
Various combinations of using the Alt, Ctrl and Shift keys (alone or together) can invoke features or shortcuts not generally known about. Like using the Alt key with the sharpening features Radius, Detail, and Masking sliders and the with then Split toning Sliders.
