In my opinion, it's all like you are teaching for an idiot. I don't need you to teach me these things, I am an advanced user.
Your signature has betrayed you, and you try to defend the AP. You are not objective, you defend it.

Not sure what you mean by that.

when developing HDR images there is the danger that with RGB color mode you get color faults, because RGB represents color and luminance in the same value.
If Affinity Photo would enable a LAB 32 bit HDR color mode that would solve the problem.
Because color and luminance are now separated, the large dynamic range of HDR images are mainly reflected in luminance. This prevents color faults during HDR generation.
 
By the way, I like the way Affinity Photo is adressing HDR development in the workflow.
However, because I quite regularly get color faults during development, I can not use it in many situations (see attached image as an example for such a color fault in the sky).
In this case I use my LAB 32 bit based HDR development programm (Oloneo), which produces nicer color without color faults.

Been working on a new transform tool....  It will allow you to transform a selection using points on their curve outlines.  It will also work with the new axonometric (isometric) planar functions, performing rotations on plane.

Hi,
in my file I'm able to repeatedly get a redraw fail, where after changing one object I get transparent or black parts of image and I have to zoom in-out to get it redraw properly.
Contact me so I can send you the file pls.

Currently no reference is shown anywhere as to what type of brush was used. Would it be possible to show the brush number or name in the Layers panel and in the brush' Mode adjustment dialog (both in AD and AP)? This would be useful if continuing a drawing after a break, because it would eliminate to search what brush was used before the break. Especially when a shedload of brushes is loaded / created this feature may come in handy.

APh or AD only supports its internal link embedding changes, and internal updates are not updated when external files are changed (Adobe Ps supports external change responses in smart link objects)

I am a beginner in LAB attempting to apply the writings of Dan Margulis, who uses only Photoshop, to Affinity Photo. The LAB underlying functionality is mostly OK, but I have found that the AP user interface could be improved in several places. More experienced users, please comment.


 
1)  In the Curves adjustment layer with LAB selected, the A channel curve is colored green and the B curve magenta. The appropriate colors are green left and magenta right for A; blue left and yellow right for B (with light or high luminosity on the right).
2)  Creating a check box on the A and B curve windows for Intersect Midpoint would make it easier to construct color-intensifying curves. This is probably the most important basic move in LAB, and even Photoshop does not have this feature.

3) The Input Minimum and Maximum default to 0 and 1. Though I have not found a use for these, shouldn’t they be -1 to 1 or -100 to 100 or -127 to 127?

4) The Curves/LAB window’s second drop-down menu offers Master, L, A, B, and alpha. Is there a known use for ‘Master’ as in RGB? Nothing I have read about LAB indicates that there is. For that matter, is there any use for Master in CMYK? And how about ‘All’ as an alternative to Master in RGB? Furthermore, the histogram curves displayed for the LAB components here are not positioned the same as when one transforms the document to LAB and displays its histograms. May relate to previous point (3).

5) Photoshop can display the graphs of the various color space curves with the light (high-luminosity) side on the right or left (one-click toggle). This option would be useful to people learning from Margulis’s books, which show dark on the right.

6) Other Affinity users have called for improvements in the Curves window in general, not just for LAB: more precision and ways of placing nodes, a larger or scalable window, saving curves.  Because of the sensitivity of the A and B curves to small movements, a fine control on node dragging would be handy, e.g., option-drag would reduce the motion by 1/5 or 1/10. Perhaps it already exists.

7)  A LAB curves user on this forum called for a keyboard shortcut to move among the channels. Why not? He needs efficiency in a much-used workflow application. In the same vein, having selected the color space, instead of a second drop-down, radio buttons for the three or four channels would slightly simplify choosing one.

8)  In the Channel Mixer adjustment layer, the LAB window A and B sliders need appropriate coloring like the RGB and CMYK. Just for consistency.

9)  The Levels adjustment layer makes sense in RGB, but I am not so sure about LAB and CMYK. Does this lead to a useful correction? (Please help me, advanced users.) If you push the existing RGB colors to the AB limits of +/-127 won’t you just create out-of-gamut colors that will have to be distorted back in RGB space? And is gamma defined for this color space? Also, in the LAB window, shouldn’t the correct labels for the sliders be, for the A channel, green and magenta, and for the B, blue and yellow. Similar questions for CMYK.

10) The Apply Image filter and Channel Mixer adjustment layer seem as if they should have similar functionality, but their capabilities and interfaces are rather different. My understanding of Apply Image in Photoshop from Margulis is to blend or replace channels one at a time, sometimes across color spaces, but to do that in AP one has to create a gray scale image of a channel in a layer and make that the source. The destination seems to be all channels of a selected layer, or does one have to separate out those channels as well? The Channel Mixer is designed to specify a single channel as destination, but it appears the source must be in the same color space. Shouldn’t these two processes allow individual choice of source and destination channels in all color spaces? Are equations (Apply Image) and sliders (Channel Mixer) of equal value in practical applications?


 
I don’t think this exhausts these issues, but this post has already exhausted me. My compliments if you have read this far. If you want to know more about Margulis, use a search engine or post here and I will try to summarize what I have earned from a large corpus of writing.

Linking an image instead of embedding it, would be useful if you're working on different documents with the same file, i.e. a logo in a design phase. So if you change that logo it will be respected in every file it is linked.
Besides that it doesn't increase your Designer file, that could be crucial if you're working with large files and make a lot of versions / copies of your Designer file.
I think it's like the new version of the Photoshop Smartobjects (CC version).
 
Would be great if this makes sense to you too and isn't too hard to implement. Thanks!

I've just added a video about differences to my InAffinity channel:
 
 

I will need to check how Photoshop handles this myself. But it just looks broken to me.
You really need to get Photoshop and test AP functionality against it. This is your only real competition. In the end it does not matter what the reasons for design choices are. If it feels wrong to the end user then it is wrong.
Sounds to me like you may be being fobbed off by the programmers. I was as a programmer for over 35 years. I know all about fobbing off producers. You need a producer who is just as good as the programmers at programming
 

Hallo!
May I show my problem?
I want to change the size of the selection brush by using "alt+left+right mouse button. When I now move the mouse to the right or left side, there appears a second, blue circle, which shows the wished size. The first white circle vanished, when I unhand the keys. And then, I think, the white circle jumps around "uncontrolled" in the picture.
This is very strange and disturbing behavior. Video shows several times, when I move and stop the mouse and start again. Always with pressing alt+left+right mouse buttons. And the jumping circle. It's confusing to work with two circles. Is it a bug or a feature? 
(Please ignore the read circle in the video...)
Btw: Using the keys "Alt Gr+the square brackets" works very well...
Thank you for an answer.
Best regards
Peter
PS: Bug(?) appears in the current beta and in all other versions before.

Would be nice to have adjustable x and y sizes for displacement map as well as what to do with extra or not enough pixels (wrap around, etc). 

Hi,
The Affinity Photo has such hotkeys as Space + Mouse for moving canvas, Space + Ctrl + Mouse for changing zoom. But I don't understand why there is not such hotkey for canvas rotating. It would be perfect if I could press Space + Shift + Mouse and to rotate it very easy and fast.
I can do it on iPad, but it is not possible on Desktop. I know that there is some keys, which allows to rotate it +/-15 degrees, but it is absolutely useless. Look how it works in Photoshop. There you need to hold R and you can rotate it as you want.
It would be very useful for digital drawing, because of our anatomy sometimes we need to change angle of our view to be able to draw a line with correct form. In the same time another angle of view allow to find some mistakes in a picture we draw. I think it is useful and simplest for developing feature that can be implemented.
Watch this and see how often it can be used: 
 
 

Hi Ωmega,
Welcome to Affinity Forums
GPU acceleration will come to Windows version as well. It's currently being worked on. Please bear with us.

It won't be CUDA, as that is NVIDIA only.
