JayR Posted April 3, 2023 Posted April 3, 2023 (edited) When I select the Delete Background Erase tool and start using it I often find that the results are strange and it does not appear to be deleting correctly until I notice that it has reverted to 10% Tolerance. It seems to keep reverting to 10% although I am not sure of the exact conditions that cause this (after opening a new document? Colsing and openeing Affinity Photo?).

Alfred Posted April 3, 2023 Posted April 3, 2023 Are you referring to the Erase Brush Tool? Quote Alfred Affinity Designer/Photo/Publisher 2 for Windows • Windows 10 Home/Pro Affinity Designer/Photo/Publisher 2 for iPad • iPadOS 17.5.1 (iPad 7th gen)

It is the Background Erase tool not the "Delete" tool. The Tolerance appears underneath the Snapping icon. Quote

The Tolerance appears underneath the Snapping icon. Thanks. That makes it much clearer. As far as I can see, the Tolerance for the Background Erase Brush Tool has always defaulted to 10%. If you check the Sample Continuously box, and drag the tool, it will set the Tolerance automatically based on the pixels you pass over. Perhaps that's what you're intending as your operational mode?

I can confirm that the Background Erase tool will always default to 10% when opening/creating a new document in Affinity Photo currently - unfortunately there's no way to change the default tolerance value of this tool at this time, my apologies. May I ask what value you are hoping to set as default for this tool? I'm certainly interested to hear of your workflow and would be happy to pass feedback through to our developers when I have a better understanding of your use case Quote
JayR Posted April 4, 2023 Author Posted April 4, 2023 I am a fairly unsophisticated relatively new user of photo editing. All I want to be able to do is erase areas of the image so that the corresponding areas from the layer below show through. This is what I used to do in V1. Recently in V2 I have found that often when I start to erase an area on the image only small sections of the area that I have erased have actually been erased. I found that by setting tolerance to 100% everything that I brush over gets erased. However, the tool does not seem to stay set to 100% so next time I go to use it I encounter the same probelm again.

Dan C Posted April 4, 2023 Posted April 4, 2023 Thanks for verifying that for me! If you are setting the tool to 100% tolerance then this will simply act in the same manner as the regular Erase Brush tool, which doesn't require a Tolerance setting. If you select the small triangle to the bottom right of the Background Erase Tool you should see the Erase Tool flyout, where you can select the Erase Brush tool - Hopefully this should function as required in your workflow, without the need to adjust the tolerance each time Quote
JayR Posted April 4, 2023 Author Posted April 4, 2023 Ah, I didn't realise that there was >1 type of erase brush!! I'm not sure how the type got changed to Background Erase. I need to mug up then to find out what th Erase Background does! Quote
Dan C Posted April 4, 2023 Posted April 4, 2023 No problem at all, hopefully this makes the workflow easier for you! 6 minutes ago, JayR said: I need to mug up then to find out what th Erase Background does! Essentially, this tool detects the colours of pixels beneath the brush and tries to erase pixels of the same colour, useful if you are erasing a sky from your image for replacement, for example. The tolerance option controls how 'similar' the pixel colours need to be, to be included in the erase - which is why a 100% value erases everything. You can find out more about this here - https://affinity.help/photo2/English.lproj/index.html?page=pages/Tools/tools_backgroundEraseBrush.html?title=Background Erase Brush Tool I hope this helps JayR 1 Quote
