Is it safe to register Sattva descreen?

[ninaschw]

I bought the professional version of Sattva descreen, and had already downloaded it, when I discovered that the product--which I had read many enthusiastic posts about--is Russian. In order to unlock it, I need to register with personal information on a third-party Russian website that may be vulnerable to hackers. I don't want to do that.

Has any other company developed a descreen filter that gives good results? 

Why hasn't Adobe developed this much-needed product?

Many thanks,

Nina Schwartz

I thought better of it and deleted Sattva descreen.

@J453 may move this thread to Ideas unless tricks to imitate Sattva Descreen plug-in are found.

Thank you, Jeffrey. I think there is a problem with this classification, though. Descreening is not an Idea; it is a filtering tool. 

Many graphic designers who grew up in the 1980s-2000s are unfamiliar with print-specific terms such as halftones and lpi (lines per inch—shows you what an antique I am!) The result is that when you search the term "descreen" you are often sent to sites that discuss how to ADD screen effects. It's better to search on "remove halftone dots."

The plug-in I downloaded free from https://ft.rognemedia.no/ (it's a Norwegian company) works the same way as does the Sattva descreen filter; it uses star suppression to remove overall patterns such as halftone screens and old photo paper with its annoying light-catching hexagons, without losing image detail. 

Best wishes!

Yes, we understand that. "Ideas" is the official Photoshop feature request channel, and maybe this functionality could be built into Photoshop - if enough people vote for it.

Historically Photoshop's filters have been rather basic, while more advanced functionality like descreen, bokeh, starfilter etc that require more extensive processing has been left to third party plugins. But there's no firm line, and if enough people request it, it may be worth the effort.

My old 'free with the PC' Adobe PhotoDeluxe software had a pretty nice/effective moire pattern filter. Also a one button "Instant Fix" and "Intellifix." Made me mad at myself when I finally tried them one day after having been manually 'messing with images.' It didn't always do miracles, but was a lot faster and easier than most of my manual adjustments!!

Of course, I had a smaller CRT monitor, etc.

Hi there! I thought I might want to chime in and say that I have been using Sattva for many years and so far it has been absolutely indispensable in my workflow. I signed up before the war and though I have had no issues, I did mention to the developer that I was worried that I may not be able to update or re-activate my licence one day due to the unfortunate circumstances that are happening. He understood and assured me that he will let me know if he is in any situation that may affect his business. At the end of they day, it's up to you but for me, I haven't had any issues. I use the Pro version 6.5 on my M1 Mackbook. Oh, that reminds me. As of now, the plug-in only runs in Rosetta so I have to launch PS in order to see the plugin in the Filters menu.

Cheers!

I've had decent results using the Median filter:

Since the Median filter only takes integer values, it's usually necessary to scale the image up, run the filter, and then scale it back down, to minimize artifacts. It's also important to rotate to accommodate the screen angle, and then back again.
