splashmob Posted March 11, 2021 Share Posted March 11, 2021 i'm new to Affinity Photo, and am very interested in using it over Photoshop if possible. i'm on the 90-day trial right now, and after looking around the program (and the forums), i couldn't seem to find anything equivalent to Photoshop's Noise gradient roughness. i make a fair bit of art mainly using that, and other Photoshop alternatives i've tried don't have it, so i was hoping Affinity would have something similar. is there any way to create something like this within Affinity? within Photoshop its pretty easy - take a gradient, set its type to Noise, and set the Roughness to 100%. attached is an example of what i mean. any help with this is greatly appreciated, as i'd like to be able to switch to Affinity if i can. thanks! (additionally, one last note - if i try to import a .PSD file with these types of gradients into Affinity, it won't work as the "Noise" type of gradient isn't currently supported.)

NotMyFault Posted March 11, 2021 Share Posted March 11, 2021 Hi, the procedural text filter may be able to produce these noise gradients. Unfortunately, the documentation of the numeruous noise functions is quite sparse (perlin, cellnoise, simple, directional, ...) If someone has deeper knwoledge about all the noise functions, we might find a combination of functions and input values to provide a similar result, at least for RGB color model. Currently no color format conversion function for RGB<-> LAB is documented. I just played a little bit, adding some trunc/ div / mod functions may provide a harshness parameter.

NotMyFault Posted March 11, 2021 Share Posted March 11, 2021 And this formula can be used to manage harshness: Quote Mac mini M1 A2348 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 iPad Air Gen 5 (2022) A2589 Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.
