When you want to process a color infrared picture, you have to use the channel mixer and invert the red and blue channels. Can that be done in Affinity Photo? Can anyone explain it? I'm really a newbie in using Affinity Photo and find it complex compared to what I use normally (ON1 RAW 2019). For your information, I'm the guy who has made available in Dropbox a PDF file of the instruction manual last year. I got a lot of feedback out of that. Thanks for your help.

The way I did it is easy. I open the Photo help page and do some copy and paste in a Word document. Then I edit the document and generate an index. After that, I save it as a pdf document. That's all but it's a long process. I don't think there's a copyright issue since everyone has access to the help pages in Affinity Photo and can do the same thing I did. If Serif doesn't approve of what I did, I'll simply remove it from Dropbox.

I have been doing some testing in stacking pictures I took of the Orion nebula. The pictures are good and the stars are pinpoints. The problem is that I tried all alignment parameters and the result is never aligned. I had high hopes for this function but it doesn't seem to be very good. Stacking is one of the main reasons I bought Affinity Photo, the other being to replace Photoshop Elements. I could always use Deep Sky Stacker but I had great hopes for affinity. I could always try to align manually but that's a lot of work. Anyone has ideas?

I only do copy and paste and some editing to shorten the document. There are things I can't do unfortunately. I am working on a new version which should be shorter.

Patrick, it is a pdf of the whole help file, all 654 pages of it.

When you enter text, there are two Windows with colors in them in the upper part of the screen. One is normally black but you can change the color and it will be the color of the text you select. This is not mentioned in the help file, I wonder why.

I have produced a pdf version of the Affinity Photo manual that you can read without starting the program. It can be interesting to put it on your phone or tablet to read when you have some time to spare. Since the file is too big to upload here, I have put it on Dropbox for you to download. It is current for the last version of Affinity Photo. Comments welcomed. Here is the link:

When you edit in HDR mode with a brush, there is an option called "edge detect" which keeps you from crossing an edge and simplifies brushing. Does that same option exist in the regular persona of AP? I'd like very much to use that when selecting the sky to replace it with another sky. I haven't seen it.
-
I had seen these 2 videos and found them interesting. But, in ON1, it is much simpler to do what I want and it can be done in a single operation, not by using channels. As to the refining, it doesn't come even close to the perfect brush for doing the job in ON1. You simply hover near the edge and everything gets selected. Well, we can always hope.

In ON1 Perfect Photos, there is way to select the sky which works by color range so the sky pieces that are in between the tree branches can be selected without touching them. When the whole sky is in a mask, you can then modify it or simply replace it with another image. I would like to see a similar option in Affinity Photo and I think a lot of people woud love it. Maybe there ia a similar option in Photo but I haven't seen it. Another item in ON1 is called the Perfect Brush. It permits selecting near an edge without getting close to it. If the center of the brush doesn't touch the edge, everything near will be selected. That would be nice also.

I just had an idea. The concept of Deep Sky objects is taking a picture of a very dim subject in a supposedly black environment. I'm going to put my camera on a tripod and take a few very underexposed pictures of a barely lit subject on a black background. Then, I'll stack them using the different modes in Affinity untill I get a good exposure. I think this should give me an idea of which stacking mode is the best for that kind of subject. Any comments?
-
Thanks James and Strikele. I found a stacking mode that adds all the exposures together and that's what I need but I'll also try the maximum mode. As to Deep Sky Stacker, I have used it a few times but never got interesting results. Most of the time it rejects 90% of my photos. I am a member of the Deep Sky Stacker Yahoo group. My Pentax K3 does have a mode to do stacking but it would have to track the subject. I prefer to take many pictures and use software to add them. This can be done in Photoshop but I don't use that software.

Thanks MEB. It's interesting.

It would be interesting to have a PDF manual that could be printed. Hope it will come one day.

Thanks, I'll look into it.

Finally, I found where the profiles are stored by Affinity. I'm in Windows, not OS X. Thanks anyway.

I want to install a few ICC printer profiles to send my photos to an outside printer. Where should I put them in Affinity? In what subfolder should put them and how do I tell Affinity that they are there? Thanks.

When you want a picture of a deep sky object like Orion, you normaly have to expose for a long time with a guided telescope. A simpler way is to take many pictures and stack them to add the information from each picture and get a much brighter one. How should I do this in Affinity? I need to add all the pictures to simulate a longer exposure. This is not HDR or focus stacking, just adding data. Thanks.

When I installed Affinity yesterday, it came out in French because my Windows is French. How can I get it to work in English? Do I need to reinstall it or is there a language parameter? Thanks for any help.

Thank you very much. It answers my question perfectly.
