Settings for Granularity -- Unknown Short Cut Key?

Much as I love Photoshop, I will occasionally hit a combination of keys by mistake that unleashes a shortcut to change some settings. It can be infuriating to undo when you don't know what keys you hit. This time, I did something that increased the scale of granularity, most noticeable with photos, but not only there. When I hit "blur" or "blur more," the issue fades -- but the core issue isn't really solved. What did I do that made my original photos suddenly look more grainy when they never did before I hit that magic combination of keys. I'm developing a strong hatred for shortcut keys!

Thanks - got your file - nothing unusual about it .

It looks like this here - section at 100% zoom and lower zoomed out. Again nothing unusual.

So , given that it is definitely not the file, I would now reset Photoshop Preferences. Go to Preferences > General and then click Reset Preferences on Quit. Click OK then close and restart Photoshop.

Photoshop's preferences contain a lot more than the user settings and are saved every time Photoshop closes. If they become corrupt, it can lead to all kinds of strange behaviour.

That's a scanned reproduction with a halftone screen (dots). Or what's left of it - it appears to have been downsampled a bit from the original.

So you have a halftone dot pattern in the original data, which at different zoom ratios may cause various interference effects. Those will disappear when you view at 100%.

In other words, there's nothing wrong with Photoshop. It's the file. A halftone screen is in fact very difficult to get entirely rid of, and you need to take several precautions when using such material.

Also, on a side note (not the issue here) I'd recommend converting to a standard profile (sRGB or Adobe RGB) instead of the Epson profile.

I thought that Dag - which is why I asked for the original. The downsampling here does not look anywhere near as bad as the OP's screenshot. It actually smooths the dots out, as I would expect. I would still try the preference reset

“which is why I asked for the original.”

The original can be found at Bruce Springsteen’s website, Dave. The copyright information is at the bottom right in the gray box.

Bingo! That did it. Thank you SO MUCH! To be sure I'm tracking with you, it appears that whatever caused the distortion was just a errant glitch as opposed to the result of accidental combination of short cut keys, i.e., this was not an actual setting. Is that right?

If not, as I whined on another post, I do think the Adobe wizards go overboard on some of these short cuts and end up catering to a very small percentage of users on many of them. I'd bet good money that the vast majority of users don't have a clue about the supposed time saving advantages for more specialized/esoteric tools (and probably get far more annoyed with the confounding repercussions of typos). I would be very grateful for an opportunity to slap some of these software designers into bigger picture sensitivities. Do they have a booth at the Photoshop conferences for such catharsis?

What do your photos look like in other programs?
If in different ways, could you provide a screenshot that shows the difference?

To be clear, the change in appearance within Photoshop just started to happen -- instantly -- when I hit that unknown combination of keys. But, to your question, attached are two screen-grabs of the same file -- one in the Photoshop [exaggerated granulurity] and other in Paint 3D. You'll see the difference right away.

Can you post the file so we can take a look at it

Whatever combination of keys that you hit, if you look in your history panel it will tell you what Photoshop did. You can back it up and if you hate that keyboard shortcut, then go under Edit>Keyboard Shortcuts and make your own or remove the keyboard shortcut you do not like.

Thanks for the suggestion. That WILL be extremely useful. However, the problem with granularity started several a couple of months ago and I've just been living with it...annoyed. Had I known what you proposed, it would been the solution. So, again...thanks for that.

Do you know of any setting that affects granularity? It's not related to pixel resolution, so I'm still puzzled. I wondered if it's related to the scanner somehow.

Maybe if that will be solution set your workspace with configuration of own shortcuts.
