    Hey Omprakash Selvaraj,

    I've heard back from the developers and this is by design.

    We use the same maths as can be seen in this PDF spec (the same as Photoshop)
    https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdf_reference_archive/blend_modes.pdf

     

     

    Yes. I understand that Adobe works that way too. Because Luminosity is to be retained from bottom layer on most occasions.

    But latest version of GIMP offers two kind of "HUE" blend mods one that retains Saturation and Luminosity from bottom layer and another "HUE" blend mode that retains Saturation and Lightness from bottom layer.

    Hope we expect this in future version of Affinity.


  2. Software version: Affinity Photo Beta 1.7.0.243.

    The Hue Blend mode in affinity is taking Saturation and Luminosity from bottom layer and Hue from Blend layer. 

    Could anybody suggest is there any blend mode that retains Hue and Lightness from bottom layer and Hue from blend layer.

    Bottom Layer: HSL (300, 100, 50)

    Blend Layer: HSL (100, 100, 50) (Blend Mode Normal)

    Result with Blend mode Hue: HSL (100, 100, 30) Vs (What I want is (100, 100, 50) )

  3. What is the advantage of doing tonal corrections in "Develop Persona" when compared to do the same changes in "Photo Persona" in RGB 16 bit mode?

    My usual workflow is:

    I open a RAW file in affinity. Just set to output profile Prophoto and color depth to RGB 16 bit. Then click develop and go to Photo persona and do the tonal changes there. 

    Am I loosing anything by skipping the RAW development and directly going to Photo Persona with 16bit image?

    Thanks

    There have been topics posted about this already, and the bug has been acknowleged. The Develop process, when developing to RGB/16, is assigning a linear ICC profile rather than the proper profile. If you check the context menu in Photo Persona you'll see it says "ROMM RGB ISO...  (Linear)". Until the bug is fixed you can go to Document > Assign ICC Profile... and assign the non-linear version of the profile.

    Thank you Walt. I just observed that the issue is there for 32bit image also.

    Hi squeezer,
    Open a RAW file go to menu View ▸ Assistant Manager..., make sure the RAW output format is set to RGB (16bit). If it's already set as such, develop the file and you should be able to assign the non linear profile going to menu Document ▸ Assign ICC Profile (the sRGB is usually on the bottom of the list). If the RAW output format was set to 32 bit, change to 16 bit, close the RAW file and re-open it again. Follow the steps I described in. the beginning of this post.

    So """Document ▸ Assign ICC Profile""" should be done by user every time they open a raw file right? (until this is fixed)

    Same problem with Nikon and Olympus files , Assign ICC Profile to assign to my calibrated monitor profile and it corrects it, however I dont wish to have to fiddle with this each time. 

    I am not sure if you should assign your calibrated monitor profile in there. Ideally you should assign the profile the camera assigns to the image. If you assign the calibrated profile again, then there is no use of calibrating. The calibrated profile is already used by your monitor and you monitor is showing colors correctly. 


  7. Verified that this issue is not happening in previous beta versions.

    Steps.

    1. Open a RAW image in Affinity photo

    2. Click develop button in the "Develop" persona and go to the "Photo" persona

    Issue:

    Now in the Photo persona, the image looks washed out compared to the image that was shown in Develop persona. I understand that, Clipping to 8 bit is no longer done in new version. But it should be consistent between how image looks in "Develop" Persona and "Photo" Persona.

    Now after clicking develop the image is shown in Photo Persona:image.thumb.png.15228c13c8b14893ff07efe3c5b8c2bb.png

    nicely done. I'm guessing that is a popular spot for such photos 

    going be the image on my scene, I feel a little darker/more contrast could be added  (??)

    Thank you ianrb. You are spot on. I was wondering something was missing from very beginning. Yes. More contrast makes this shot even more beautiful. Thank you!

    Hi, Tks for your answer but I don't use Wacom hardware but only the Surface pen together with My Surface Pro 4 and I don't have any drivers to update. Any other suggestions?

    I believe proper drivers will solve this. They default generic pen drivers that comes with Windows has this issue we reported. 

    Try uninstalling the existing pen drivers and reinstall them.

    The another reason could be because of one Windows 10 update that messed pen behavior.

    Same problem here with stable version 1.6.5.123 on a Surface Pro 4; using the Surface pen with the brush tool I have only a pointer visible on screen and if I want to see the brush size (the circle) I have to move the mouse on the active area first, after doing so the pointer turns into a circle and I can use the pen, as Omprakash Selvaraj described.

    PS: "show brush preview" enabled or disabled doesn't change anything.

    Please check my response above.

    Hey Omprakash Selvaraj,

    I've seen this reported before but a lot of the issues in our database are marked as fixed regarding brush previews.

    What model are you using and what driver do you have installed?

    Do you have 'Show brush previews' enabled in Preferences > User Interface? 

    'Show bush previews' were enabled by default.

    What helped me in this case was Installing Wacom tablet software from Wacom site. This updated pen and tablet drivers.

    Now it is working.

    Thank you Chris for reminding about drivers. 

     

     


  12. I am using Wacom Pen and tablet for retouching on Affinity Photo 1.7 beta.

    The issue is that when I use wacom pen and go and click Brush Icon in the tool box and come back to image area, the cursor or pointer still appears as pointer instead of round shaped brush.

    For bringing round shape, I always have to move mouse slightly and then start using the pen.

    This is not show stopper, but a real usability issue for pen users. We have to place the pen down and use the mouse just to bring the cursor into brush shape and then start using pen.


  13. Affinity Photo 1.7 beta completely replaced my Photoshop needs. 

    I would like to have a Digital Asset Management software like Lightroom from Affinity. This will enable culling and then taking them to Affinity Photo for more detailed work.

    So how to do image management until we get another gem from Affinity?

    Nikon View NX-i does the job for basic image management. View NXi + Affinity Photo is a true replacement of subscription based Adobe Photography CC plan.

     

    Right Click The Image you want to take to Affinity Photo.

    Open1.thumb.png.468f2dde6c8a2235a9c22414b5347621.png

    Register If you have not registered before.

    Another way to take your image to Affinity Photo.

    I'm sure that Serif will work on updating the videos, once 1.7 is fully stable and released. Until then, any video they might make showing new or changed features is likely to become out-of-date as the code is modified during the beta process.

    Thank you Walt. It looked like the courses had been created and list was last updated on 2015. But we got 1.6 release in 2018 this year March. So I am sure, there are things to add.

    But not a show stopper. We can manage to use those features by seeing features list.

    Issue solved! This is useful to subtract one layer from the other, for example for Frequency separation.

     

    So this is how I did it for a 8 bits image (16 bits should need a change in the 2 and .5 values bellow)

     

    1 - Create two layers with the same image 

    2 - Change the layer bellow as you like (gaussian blur, median blur or anything else)

    3 - Make the top layer Linear Light (could be done afterwords but if you do it before Applying image, it's easy to see the result as it happens)

    4 - Apply image with the following parameters:

    Source: layer bellow modified

    Blend mode: Normal

    Equations: on

    DR=(DR-SR)/2+0.5

    DG=(DG-SG)/2+0.5

    DB=(DB-SB)/2+0.5

    DA=DA (no change to the Alpha )

     

    A couple of explanations. In the equations:

    DR stands for Destination Red an is the value of the Red in the layer you chose to Apply image (in this case the top Layer)

    SR stands for Source Red and is the value of the Red in the source layer (in this case the layer bellow)

    The 2 and 0.5 are based on this info: https://helpx.adobe.com/photoshop/using/channel-calculations.html (look for "Add and Subtract blending modes")

     

    Hope this helps for future reference.

    Well Done Martin! I was looking for this. Excellent job! Thank you!
