| p.1 #9 · Question about Monitor Calibrication |
Your shadows are probably too dark. I can barely see the details on a good monitor. Not enough in my opinion. To accurately evaluate an image, look at the numbers. The monitor and your eyes may lie to you, but the numbers don't lie.
Here is a version showing blue where the RGB luminosity is 15 or less. Most monitors and eyes can't distinguish details below that level.
Here's how I made that blue image. I found this tip long ago, can't remember the source. I think it might have been in a Calvin Hollywood video.
1. Add a temporary Gradient Map adjustment layer.
2. Change the left color of the Gmap to the desired shadow clipping color (blue).
3. Change the right color of the Gmap to the desired highlight clipping color (red).
4. Double click on the blank area of the Gmap layer to access the blending options.
5. In the Blend If (Gray) section, drag the Underlying Layer sliders.
6. Move the white slider from the right side (255) to the desired shadow clipping level (10 to 15?).
7. Move the black slider from the left side (0) to desired highlight clipping level (240 to 250?).
Don't get confused because this sounds backwards.
The black slider sets the highlight clipping, the white slider sets the shadow clipping.
Put all that in an action for easy access. Before you start any other adjustments, run the action to create the "Clipping Indicator" layer, and keep this layer on top of the layer stack. Add your other adjustments below it. If you do anything to cause clipping, it will immediately show up as red or blue. Toggle the layer on and off as you work. When finished, delete the layer.
If no clipping indication shows up, go back to the "Blend If" options and adjust the sliders until clipping indication does appear. Look at the numbers to see where it happens, giving you a good idea of how much leeway you have left.
