Random crashes... sometimes caused by Preset sync:
- Close Photoshop
- Create a text file an save this as PSUserConfig.txt
- Add 'PresetSync 0' to PSUserConfig.txt and save the file.
- Move PSUserConfig.txt to the Photoshop Settings 2021 folder.
- For Windows : go to Users[user name]\AppData\Roaming\Adobe\Adobe Photoshop [version]\Adobe Photoshop 2021 Settings
- Open the Adobe Photoshop 2021 Settings folder and place there the PSUserConfig.txt file.
- If the PSUserConfig.txt already exists, copy the file to a safe place, then place the new. The PSUserConfig.txt file with the PresetSync 0 rule, will force preset sync OFF.
- Restart Photoshop. After restarting Photoshop, it should be possible to work with Ps 22.2.
use Blue channel for slope
normal map > relief shading
opacity – no build-up in same stroke
flow – opacity build-up in the same stroke YES!
example:
opacity: 100
NO pressure sensitivity checkbox
flow: 34
NO buildup effect checkbox
I try to work quickly. Instead of worrying about the “perfect” settings, I try for an acceptable, fast version. Then, assuming that it seems satisfactory, I make an even quicker second version from scratch. If it’s terrible, I discard it, but often enough it’s good enough to make an improvement when blended into my first version.
In doing this second version, I try to avoid making the same moves as in the first. So if I corrected the color of the first in RGB, I may try the second one in LAB. Probably it won’t be as good, but you never know.
Assuming that the first version is fairly decent, I try to do the second as quickly as possible, since the chances of it drastically improving the result are slim. So, if there is a color issue, I often set up a layer to which I apply Auto Color at 50% opacity. It’s true that this will not be as good as if I had custom-written the curves but it’s faster, unlikely to do much damage, and will prevent me from matching my first color effort to closely.
This new approach came after more than ten years of looking down my nose at Auto Color as a thing that no self-respecting individual would ever touch.
Some lesser mortals do actually use Auto Color as a major tool. I recently took in a YouTube video where the instructor was suggesting this. His point was that the Auto Color defaults aren’t particularly good and that we should change them, possibly on an image-by-image basis.
I am not about to do that—if there’s time to explore a new default, then there’s time to do the job properly. But I am willing to change the default permanently, if it helps what I’m trying to use the command for. And having tested it, I agree that the suggested modified default is better for my purposes, so I have changed it.
Here’s the change. Open the RGB curves dialog, and hit Options, which brings up the Auto Color settings. Photoshop’s out-of-the-box default is to use what it calls the Enhance Brightness and Contrast algorithm.
This guy suggests changing the algorithm to Find Dark & Light Colors, and also checking the Snap Neutral Midtones box, which isn’t available with the other algorithm.
I tested the two approaches with fourteen random images from the MIT set. In each case the two results were quite different. But, being algorithms, they don’t use common sense and they both get poor results some of the time. The snapping midtones to neutral works well with sky images but fails when we’re trying to get a sunny look, or on indoor shots where the walls are an off-white, etc.
