[Apply image and blend modes]

Something that would be really cool is if you could plug in formulas into the apply image interface and instead of applying it immediately by selecting a source layer within the document (a feature which the iPad version needs badly!), you could save it as a new blend mode type for use later. Basically, a much more convenient and powerful version of apply image. I know I tend to end up punching in the same formulas over and over, and sometimes the ability to define custom blend modes would be immensely useful (since it's nondestructive). A lot better than, for example, having to punch in the formula for a "divide" blend mode manually after exporting the layer to an external file so that it can be selected by apply image.

Anything that makes Affinity more customizable like this would be a huge deal, it's already a really nice framework that's not bloated... Being able to make tweaks like that would be amazing for improving the workflow in ways that Photoshop seemingly never will.

[Why I am NOT supporting the Affinity range of software]

Rather drastic post. I use Affinity Photo and yes, some features may be lacking in comparison to Photoshop, but in some ways it's actually superior, especially in concept (which bodes well for the future). And I only paid $20 for it. I've paid more for meals that made me throw up.

[Creating color chords - option missing?]

Is the option to create color chords from a color in the swatches panel missing in the iPad version, or am I doing something wrong? I've tried clicking and holding on the color with my finger (and the pencil) and the only options I see are to rename or to delete the fill. The panel preferences only offers options to add the current fill to palette, add app palette or doc palette, to rename the palette, or to remove the palette.

 

[Create manually Frequency Separations layers]

1. Convert your image to LAB mode.

2. Duplicate the layer, and name the lower one "L" (luminosity) and the upper one "C" (color).

3. Go to the channels studio for "L" and click on the "..." for AOpponent, and click "Clear". Do the same for BOpponent.

4. Go to the channels studio for "C" and click on the "..." for Lightness, and click "Clear" and then "Invert".

5. Change the blend mode for "C" to "Color".

6. Duplicate "L" and name the lower one "L blur", then apply a blur filter of your choice (Gaussian or median, etc.) to this layer.

7. Create a new group named "High pass" and place "L" inside it. Then, duplicate "L blur" and place it above "L" (inside the "High pass" group).

8. Go to the channels studio for the copy of "L blur" inside the "High pass" group, click the "..." for Lightness, and click "Invert". Set the blend opacity to 50% (blend mode normal).

9. Set the blend mode for the "High pass" group to linear light, and then rasterize the group if you wish.

 

[Create manually Frequency Separations layers]

There's an easy way to do this. Took me longer than it feels it should've to figure out, but the answer is here:

Quote

Apparently, Affinity makes the high pass layer by inverting the low pass layer, and blending it with the original layer (50% opacity, normal mode). When it is going haywire in LAB mode, it is setting the opacity of this inverted low pass layer to 100%.

I tested it with median blur as well and it works great. I agree that the median blur works better in many cases than gaussian due to less smudging of color. Also, a lot less color ends up in the high pass layer with median blur. Finally, if you want to isolate color in a separate layer, or strictly in the low pass layer, use LAB mode and do the frequency separation on the luminosity layer. Works great in my experience.

["filter" layer - make pixels transparent]

Not selective enough unfortunately. It always takes some of the other tones with it. If like in the example above you are only trying to remote grey tones you take a lot of color with it.

["filter" layer - make pixels transparent]

As an example, the ability to replace all grey tones with transparent ones, creating a layer containing only hues and transparent pixels, would be very handy.

["filter" layer - make pixels transparent]

Is there a way to make an adjustment layer that erases pixels? So you could do something like make a curves layer that removes all red pixels - and not by making them white? Or to "subtract" one layer from another? (erase blend mode seems to only care about transparency of the two layers, not opacity or color.)

[Affinity Photo iPad storage space problem]

What happens to project files if you uninstall Affinity Photo? Are they deleted?

 

Basically I'm wondering if I could uninstall and reinstall Affinity Photo to regain storage space without having to backup all my files.

[Affinity Photo iPad storage space problem]

As mentioned in the other thread this does seem to remain an issue. 

[iPad app stores a lot of trash]

I've had this same issue - always low on space as after result.

[Frequency separation - high pass B&W option?]

Here's the crude solution: take the original layer and place it above the low pass/gaussian blur layer and set the blend mode to "color."

[Frequency separation - high pass B&W option?]

Kaffeeundsalz: thanks for the suggestion! Unfortunately that doesn't solve the problem - color is still lost, the end result is somewhat desaturated. It must be an issue with the gaussian blur filter.

[Frequency separation - monochrome high pass layer?]

I was wondering if the frequency separation filter can isolate colors in the low pass layer and leave the high pass strictly B&W (textures only) like in Photoshop. Is this already possible? Am I overlooking something obvious? I've been using it for months and haven't figured out a way. I love having it as a filter and it's much easier to use than Photoshop's method, but the ability to confine color to the low pass layer can sometimes be invaluable. 

 

Naturally it’s possible to simply add a B&W filter to the high pass layer, but then color information is lost. Ideally Affinity simply confines all color to the low pass layer for this reason. (The way it is now complicates tasks like transposing a texture from one part of an image to another when the colors are both vivid and different.)

 

If there isn't a way to do this, adding that ability would be very helpful.

 

I asked this question before elsewhere (see below), and seems like there probably isn't a way at the moment... 

 

[Edit selection as layer for the iPad]

It would be really nice to have this as a one click selection tool along with the others. It sounds silly but clicking through a few menus every time is tedious if you're using it heavily. It's a great feature, it just would be a big workflow improvement to have it be more accessible. It definitely gets more use from me than some of the other tools on the toolbar.

[Affinity Photo - Color Separation]

This would be at nice feature to have. Just have to say though... Yes, Affinity lacks some features Photoshop has (and some relatively minor features missing in the iPad version) which can be annoying to work around. But I think the interface is fundamentally better and for almost everything it's comparable and often superior. Given the stage of development I'm really excited to see where this ends up 5 years from now - it will probably look a lot like the desktop PC market, now that tablets and phones have taken over. The scaffold in there, they just need to finish filling in details, and focus on the interface and core functionality, not endless bells and whistles that are often not of general use (the direction Photoshop has gone - why is frequency separation still clunky?).

[Brushing in a mask]

I've seen this happen at few times. I think I just restarted Affinity and replaced the mank layer with a new one but I can't remember for sure how I got around it. Guessing it's a bug.

[Frequency separation - high pass B&W option?]

Unfortunately, it doesn't - some color is in the high pass layer and so is lost when a B&W adjustment is used on it (ie, the image loses color in the end, unlike with Photoshop).

[Frequency separation - high pass B&W option?]

I was wondering if the frequency separation filter can isolate colors in the low pass layer and leave the high pass strictly B&W (textures only) like in Photoshop. Is this already possible? Am I overlooking something obvious? I've been using it for months and haven't figured out a way.

[Color picker for the gradient map adjustment is missing]

The color picker for the gradient map adjustment seems to be missing. The ability to pick tones from the image for the gradient map, without having to write them down and manually adjust to the RGB numbers, would be awesome. It's an extremely powerful approach to color correction in Photoshop, and the feature seems to exist in the desktop version...

If I'm wrong please tell me where it is, I can be very blind sometimes. Thanks!

EDIT: Double checked to see if I was crazy, doesn't seem to be available for the color studio/panel for any of the layer fx either...
