Thanks, this isn't exactly what I want. I'm hoping that by using three images slight movement (blowing leaves, running water, etc) will have that so called "glitch" effect and everything else will not -

How exactly do you add one channel from one photo to another? (Make a new document and add the Red channel from the first photo) -

Ok so I use a M monochrome and colored filters (although why not make greyscale images from the RGBs for each channel?).......... how do you take those three greyscale images and make an RGB? -
I have seen a technique referred to as "trichrome" where the photographer took three exposures of a scene on black and white film. One with a green filter, one with a blue and one with a red. He then scanned them and brought them into photoshop as greyscale images and used a command called "merge channels". The result is an RGB image. I'd like to duplicate this effect with 3 digital RGB images; using the red channel from one, green from another and blue from the third. Ive experimented with stacks and just a layered document with no success. Does anyone know how to achieve this? link to the video:

Cropping to size
johnk replied to johnk's topic in Pre-V2 Archive of Affinity on Desktop Questions (macOS and Windows)
Well I used 85:55 for the ratio and it works. Seems odd, is that the only way to do it? -
I have an image I need to crop for a half page ad (8.5"x5.5") and then reduce the resolution to 300dpi. I can't for the life of me figure out how to do it. The program's crop tool won't take a custom ratio with decimals and If I use "Absolute Dimensions" the crop is too small. If I try and drag it larger it doesn't maintain the ratio and drags free form. What am i missing?
