  1. Can save a selection as a channel. Subsequent selections will not be saved as another channel. Feature works as expected in Affinity Photo 1.6.7
  2. Good Morning, I have been looking for a way to create a Gaussian blur gradient. That is to say slightly blurred on one end of an object and progressively becoming more blurred toward the other end of the object. Specifically a shadow of an object (pole) composted into a photo. I have been told that there is a way to accomplish this in PhotoShop using a channel selection and applying a gradient to the selection. Is this possible with Affinity Photo? If so how. Thank you.

  3. I am currently testing Photo right now as a viable replacement for Photoshop, after 24 years. Since I do game development, there is a very necessary feature that I need to use and can't find it in AP. In order to do some special texture creation, I would need to be able to turn RGB visibility on and off individually per layer or layer group. In Photoshop, in a layer's properties, you can turn off Green and Blue, for example, and have only the Red channel show for that layer (or layer group). Then, in another channel, only show the Green channel. In this way, texture maps can be created for use in 3D programs like 3ds Max, and in games for things like specular effects and normal maps for bumps. Also, I don't see a way to make adjustments to levels on a specific channel by selecting it and making the changes. I need to be able to see the grayscale of each channel as I'm tweaking it. This is especially important in specular and normal map creation for games. Hopefully, someone here has worked in game dev and knows what I am referring to. If I cannot control the RGB visibility and adjustments in layers and groups, then Affinity Photo will not work for what I am doing. I truly hope it's in there, and I just don't see it, or that maybe it's in the works for the next version. Thanks.
  4. In Affinity Photo how can I copy a channel over another one? For example: I have color photo and I want to copy the red channel over the green channel. In other words, red and green channels should be identical. I tried making the layers editable, selecting all and copy/paste but it doesn't work. Or can that only be done through channel mixer? Can I copy a channel from another image that way? The reason I'd want to do this: I have a bracketed color photo and I'm trying to maximize detail by grabbing a single channel from one photo and pasting into another.
  5. Making the transition from PS to AP, but running into an issue of tiffs that have a saved channel we use for selection. We typically mask out parts of our images that need color correction. We make our mask and save the selection to a channel that can later be recalled to be tweaked later. In this example we have a channel called "wall" in photoshop. Opening this image up in AP gets me an unexpected result. I would expect to see the added channel in AP that I could turn into a selection as we do in photoshop. These images are placed inside a InDesign document saved as a PDF for print. Why am I getting this result and how can I avoid this without reworking thousands of high res Images that I have already have saved selection channels saved into them? If my final image has to in tiff format, I want to avoid the tiff hack of saving layers or native app formats. Is AP mishandling the channels coming from photoshop? I can however, take an image and make a selection in AP save the selection as a spare channel, save it as a tiff and reopen it in AP without any issue. Coming from photoshop, it seem not to work the same. Here is what I am seeing: I expect to see this: Attached in the Tiff file that contains the "wall" channel. https://www.dropbox.com/s/kich7uu71cmi96v/FlowerCanvas.tif?dl=0
  6. There is this technique I want to replicate in Affinity Photo that can be done in Photoshop, but I can't get it to work in AP (see video link below). What I basically want to do is select all the pixels of an image from all the visible layers by using the Channels window, create a new layer, and then finally fill the entire selection with a single colour that has translated the shades of the selection into transparent pixels (i.e. pure white is 100% transparency, black is 0% transparency, and grey is everything in-between those extremes). Video link in question: https://youtu.be/WZOJqbSBPxI?t=7m1s
  7. Would be good if we could record the renaming of spare channels within a macro.
  8. Trying to follow the Affinity Photos Edge Detection for Masking Tutorial on 2017 iMac 5k, High Sierra. At 3:22 The possibility to "Load to Gaussian Blur" has disappeared in my version of 1.6.7 that I downloaded from the App Store yesterday. Am I doing something wrong? or is it a bug? If it is a bug, does it affect all channels manipulations with live filters or only the Gaussian Blur?
  9. Hello, I'm a game artist, and the main thing preventing me from switching from Photoshop to Affinity is that we use channels (R, G, B, A) differently than you probably expect. We basically need direct access to every channel (including alpha) as an individual editable, grey-scale image. Each channel holds distinct texture data that we feed to shaders. For example, I often need to tweak the levels on just the alpha channel, or invert just the R channel. This is doable in Affinity, but it is very cumbersome. In particular, the way that Alpha is always displayed as layer opacity makes it almost impossible to treat the alpha channel independently from R, G & B. Alpha often holds data that has nothing to do with layer transparency. To enable game artists to use Affinity, we need access to all of the channels and the ability individual manipulate them. Thanks! Ocean
  10. Is it possible to rename spare channels in a macro? Thanks!
  11. In Blend Options for an image in RGB, I can only choose Master, Red, Green and Blue to control blending. However in Curves I can work with LAB channels even if the main colorspace is not LAB. It would be very good to be able to choose LAB channels in Blend Options the same way. Color channels of LAB are fantastic to isolate an effect or adjustment to certain objects / areas of the image in a dynamic non-destructive way that masks can't reproduce.
  12. Masks, everybody has to do them, why not manage and utilise them in a meaningful way? We could bring in external masks/alphas paint grayscale layers or have selections saved as channels. We could bring them in as linked images or embed them to the document. Each time we create a new adjustment or filter layer we have to either go through the channels, create a selection from a channel or rasterise an existing grayscale layer to a mask. That's the inefficient time-vampire kind of way. How about letting us store and manage channels in a meaningful way? Example: I have a mask drawn and want to move on from it to recall later. I could right-click and select "Store as Single-Channel… > Select / New channel" or "Store as Multi-Channel" for additional RGBs like normals or object coordinates for relighting. (In the channels list RGB sets would be displayed as a channel group, users can also create channel groups, RGBs are just automatically generated for the user) When I need that selection in a tool, the tool would just have a dropdown menu listing all the available channels (incl. RGBA) and I could select the mask I've just made. If I make changes to that mask, all tools using that mask update automatically. No hassle, no extra time cost.
  13. Ordinarily, when a TIFF has been saved with 'Save Affinity Layers', if you re-open the file to continue working on it, then re-save it, Affinity Photo recognises that there are multiple layers and therefore the layers and spare channels are all kept intact. If however there is only one layer, Affinity Photo doesn't recognise that there are Spare Channels present when re-saving a TIFF file and this results in the spare channels being deleted from the file when saving it. To replicate the issue, carry out the following steps: 1) Open the attached ZIP file (it contains a TIFF with an alpha channel and a spare channel) 2) Draw on the bottom layer with a brush 3) Press CTRL + S to save the document and close it 4) Re-open the document and the layers and spare channel are all intact as it should be Now carry out these steps: 1) Open the attached ZIP file (it contains a TIFF with an alpha channel and a spare channel) 2) Draw on the bottom layer with a brush 3) Delete the layer with text on it 4) Press CTRL + S to save the document and close it 5) Re-open it and the spare channel is now gone I think Affinity Photo needs to check whether there are spare channels before saving, so that it doesn't delete the users spare channels from the document. In addition, it also needs to check whether things such as text layers are present too, because if you have a non-rasterised text layer it will also be flattened when saving, rather than keeping the layer intact.

  14. I need to take two files and move them into one. What I have is a bmp file and then a second bmp with the alpha information. How do I combine these two together to give the first image transparency? I used to know how to do this in photoshop but I can't figure it out within Affinity.
  15. I've been looking all through Affinity Photo for Ipad and I can't find a way to isolate channels on one layer only. Here's an example of what I want to do, done in Photoshop (double exposure): https://www.graphicadi.com/create-double-color-exposure-effect In Photoshop there are advanced blending modes where you can select which channels are visible on each layer. So you can have the red and green channels visible on one layer but not the blue, and so on. Please note the blend mode selected in the example is "Normal". I'm looking for information on isolating channels, not blend modes. Is there the ability to isolate channels on each layer available in Affinity Photo? Thank you.
  16. Hi, love Affinity Photo and all the hard work you guys have poured into the software. I have a few questions about Channels and masks. I have watched your video but I still seek information. Frist off forgive me if these are simple issues, I have been working in Photoshop as a professional for over 20 years. There are techniques that are much like muscle memory for me with PS. I struggle in AP to get the result due to my lack of experience with AP. You know old dog new tricks, I want to understand Affinity better. What is the definition/purpose the of the Composite Alpha? I don't see data in the channel, even though the RGB channels show their data. Which leads me to my next question; How do I make an all 3 (RGB) channel selection? I am looking to get all 3 channel data into a single mask (luminosity mask). I would think the composite Alpha would be the place to retrieve that data. In the Channel Studio, there is a "Mask Alpha" that shows the mask I have selected in the Layer Studio. Is there a way to view this mask from the Channel Studio like when you option-click in the Layer Studio? It would be nice to view any alpha with the option-click like Spare Channels. Thank you for your help. Gauncer
  17. Sup people! I've been checking out this application and I'm really impressed with what it can do. I've been porting over my Photoshop work flows, and it has handled every task I've thrown at it. And like everyone else, I'm just looking for a little help. I've been trying to figure out the layers/channels tools in Affinity, and how to use them. I'm an environment artist and this is specific to my terrain workflow. During the production process, I've always taken my textures for a few passes through Photoshop. As part of my editing, I would use masks that I've created to edit specific areas of my diffuse texture. Example: Copy my masks into the alpha channel and start working with "Adjustments", "Layer Effects", etc. Thing is, I can't seem to get Affinity to perform the same tasks. I've checked a few of the Channels/Masks tutorials, but I just can't seem to find what I'm looking for. Either that, or I'm missing something. I have provided a screenshot of the WIP terrain, as well as the diffuse texture and masks. Any help would be appreciated.
  18. Crop an image so it is much wider than high (panorama style). Look at Channels panel. The LH image icons now fill the panel left-to-right. If you drag out the pane and stretch it sideways you can see the rest of the panel contents. Looks like when scaling icon into this panel, it is not constrained by width.
  19. So my biggest gripe with Affinity Photo has to be the channels workflow. I use my image editor for texture work for 3D and I have to be able to edit color and alpha channels. I was able to do everything I needed with photoshop but I'm not willing to support subscription models, so I would love to be able to just use affinity and not need anything else. Thanks to this post https://forum.affinity.serif.com/index.php?/topic/4730-split-channels/I was finally able to figure out how to create a layer from a channel. (In photoshop this is done by showing only one channel in the channels panel, selecting everything and hitting copy, then pasting into a new layer) Now I need to know how to paste from a layer into a channel. So that I can combine 3 separate images (or layers) into a single image/layer where each of the previous ones is one of the color channels? (In photoshop I would just click on my layer, select all pixels, copy, chose a layer to paste into, show only the color channel I want to edit and paste) Likewise how can I paste a layer into the alpha channel? (In photoshop I could chose a layer, select all, copy, chose a layer, go into the channels panel select the alpha channel and paste)
  20. Hi, I have 3 greyscale images corresponding to Red, Green and Blue channels (for astrophotography, specifically images from Juno). I know you can make greyscale images from the channels but does anyone know if there is a way to do the opposite? Import, or paste the individual images to each channel? I haven't tried this in photoshop yet. Forgot to mention, this is in AP Thanks, Luke
  21. Hi as the title says I don't know what composite alpha channel is and how I can use it. I understand that alpha is transparency but this channel is white, I've never used it but I want to know what it is and what it is its function thanks....
  22. Is there a way to edit the RGBA channels in AD? Someone posted a workaround here: https://forum.affinity.serif.com/index.php?/topic/435-i-would-love-to-be-able-to-edit-color-channels/?p=1234 but I wasn't sure what "colour page" he was talking about and it's from 2014.
  23. Hey guys, I have an interesting question. Can Channels in Affinity Photo be used as a means to separate hair in a photograph from the background. If so, how is this achieved? Also, if the explanation is too detailed to explain, is there a video tutorial that will help? Thanks a million! The Student
  24. I have used Photoshop for comic book related coloring for several years. I see great potential in Affinity Photo; however, the look of the channels is currently confusing. I'm used to seeing A "CMYK" channel and then one channel each for C, M, Y, and K. I can then create a copy of the K channel that I overlay onto the image, after I've used it as a guide to color the image. Affinity seems to give me 2 of each color channel, no main channel and no option to superimpose the Black copy. I'm hoping, if I haven't overlooked anything, that this is something that can be redesigned.
  25. Hello! I've just started using Affinity Photo on windows, and it's look promising although i can't figure out one thing. Is it possible to add other channels to work with? I'm mostly using PS to prepare files for DTG printer, where I need to create channel that represents white ink. In AP eg. when working with CMYK, there are only Cyan, Magenta, Yellow and Black channels, and I can't add my own (or i don't know how). Anyont can help me? Thanks :)
