Hello everyone, my name is Federico and I have been a happy user of the Affinity suite for a few days. I'm experiencing a problem that I can't solve when I export my pictures...I've searched on google and here on the forum but I haven't found a solution. If I open my raw image (from Canon 6D mark1) in development and then work it as a file in 16 bit and adobe rgb color format everything is fine. The image is clear and has no defects. But if I then export it to jpg I find myself with annoying bands of color in the finest transitions. I have tried various export settings but the problem persists. The only current solution that works is to export the image to PNG which in itself I don't think is a bad thing but I go from an 8 megabyte jpg to an 80 megabyte PNG! Is anyone experiencing the same problem? Or am I using the wrong export method? (I was used to photoshop). I attach some images where I hope you can see the difference between jpg and pgn. Thanks a lot to everyone for the help and forgive my english!
When using Gaussian Blur on objects in Affinity Designer (Mac version), I am always seeing an undesired color banding side effect, as you can see on the attached screen shot. I'm not encountering this issue with other graphical applications. As far as I can see it, the root cause seems to be that Designer does not use dithering for Gaussian Blur effects, even though it does dithering for gradients. Are there plans to address this? Or are there plans to support Photoshop filter effects in Designer, like it is already supported on Photo side? Because then we could use some Photoshop plugin as a workaround instead of using Designer's integrated blur effect. I find this an important issue to be addressed, since blur effects are some very fundamental technique for vector based illustrations. Using: Affinity Designer 1.8.4 on Mac.
First post here. I've been working on a composite of images captured during totality & getting some banding artifacts in PS when forced to use 16 bit mode rather than 32 bit for sharpening steps. I'd like to make sure Affinity Photos has the adjustments I need in 32 bit mode. The complete workflow for PS is describe in this tutorial by Russell Brown: PS Spin Blur Eclipse Processing From Photos tutorials, I see there are spin-blur filters, Apply Image: Equations panel & an Equations panel. So maybe everything I node is there but done differently in Photos. The key step I'm unsure about is in one of the equations panels. In PS, a duplicate image is spin blurred & the alpha channel of that image is subtracted from the original alpha w/ an off-set of 128 in the Calculations panel to give a low contrast mid-gray frequency mask. That mask is then Overlayed onto the original. I'd like to confirm that all this can be done in Photos in 32 bit mode? Here is a version of my PS work from 77 images w/ artifacts & a mask. The frequency mask reveals the finer corona detail. Thanks!
