Question

Sudden Photo anomalies. No known cure.

Hello, I've been getting "artifact" problems but have no idea how to stop them. I'm using Photoshop CC. Is there a way to zap my Photoshop program to stop these? Below is an example. I was simply trying to adjust a product screen grab. When is started going wonky, I created another document and pasted the images to start over. Same issue. Almost as bad as Spectrum TV.

Any suggestions?

Thank you, Al

If you are pulling from websites you are pulling low resolution images. You can spend a lot of time with the healing brush but working at 72 dpi with those sorts of tools is usually pointless. The mistake you are making, if I'm understanding you correctly, is you are using low-res art in your production phase. Simply, you're doing it wrong lol (jk).

Start with high res versions, then save down to web-spec/svae for web/export... whatever.

I appreciate the thought. And I'd never use a low-res image for something important. It was actually for a friend as a simple diagram. On the other note, the problem presented itself as though Photoshop had become corrupted in some fashion. The moment I dragged an object through the image, a trail of pixelated squares would follow my path, like a comet tail. Some were just large blocks of color. I'd never seen such a thing, at least, not since my first $10,000 Mac from 1989 :-). It was odd enough for me to panic a bit. I'll keep my fingers crossed that it doesn't show up again.

Whilst the advice to use images with higher pixel content rather than screen grabs is sound, that is not at the cause of your on screen artifacts. Low res would show as pixelattion not as the additional large blocks shown in your image. Also ignore the reference to 72 ppi - it is irrelevant and just a meta data value inserted by Photoshop into any image that arrives without the ppi metadata set. The number of pixels matters the ppi is irrelevant until you a. Add text using point values or b. send to print.

Yes it makes sense, but I can't get it to happen here

You may want to try a Preference Reset (Preferences >General >Reset Preferences on Quit)

Ok , Try this.

Go to Preferences >Performance and temporarily turn off Use Graphics Processor. Restart Photoshop.
Try the image with the same actions. Do you still see the issue?

Thanks, Dave. When I accessed the preferences menu, the Use Graphics Processor was Not turned on. So, I did the reverse. It seems to have stopped, so far. My intent was to turn the thin lines to be parallel to each other. Each line is on a separate layer. In my previous version of Photoshop, the layer menu would show the layer as having a thin line. After spinning the lines on their axis now, the layer panel looks like large rectangles, as though the lines have filled in the space they spun in with red. Does this make sense to you? Is it a quirk of the CC version? If I don't get any other anomalies, I'll simpy ignore the images in the layer panel..

Which artifact are you referring to ? The red rectangle, the pattern at the top or other?

Sorry for forgetting that one clue. 🙂 The image was supposed show 2 red lines pointing to the faucet lever. The artifact is the block of color that appeared as I tried to manipulate the red lines into place. As I continued to move the lines, different rectangles appeared over them.

Almost like large red pixels.
