Hallomo Posted October 29, 2018 Share Posted October 29, 2018 Hello! I wanted to ask you if there is a magical tool, which can remove rainbow colour, stripe noise, if you take a picture of a projection. Perhaps I need to try to reduce that while taking picture but if there is a way to get rid of these afterwhile (raw or jpg), I´m more than super happy. Thank you in advance!

Staff Lee D Posted October 31, 2018 Staff Share Posted October 31, 2018 Do you have a full sized file you could upload, it's hard to try on a snippet of an image as you don't see the full effect. Quote Link to comment Share on other sites More sharing options...

Old Bruce Posted October 31, 2018 Share Posted October 31, 2018 I think the Rainbow is the scanning line of the projector. And it can't (easily) be fixed with software. You need a shutter speed long enough to let the scanning take more than one pass. Not 100% sure.

Hallomo Posted October 31, 2018 Author Share Posted October 31, 2018 Thank you, Old Bruce! yes, I know, if shutter is slow then the line is less (first picture above). In this case, I needed to take a picture of a monitor and a projection in one, so if it´s too slow, then the monitor is way too bright. I will put a screenshot of what was in the monitor later in the picture but wanted to ask if there is any possibility to get rid of these lines afterwards.

carl123 Posted October 31, 2018 Share Posted October 31, 2018 There is no magic tool to do this in Affinity - you can play with an HSL layer on the Blues and Magentas as shown below. Then maybe use the Clone Brush Tool to remove the remaining horizontal stripe edges but it's still a lot of work for what the final result will look like.

Hallomo Posted October 31, 2018 Author Share Posted October 31, 2018 Thank you, Carl123! already so a lot of magic in Affinity, so maybe this magic will come someday too… Quote Link to comment Share on other sites More sharing options...
