lucarubino got a reaction from A_B_C in Cursor for iPad
I have a big suggest for you.
Your software is great and the hardware too (iPad 10.5). So why I still use AF on desktop all the time? Due to the lack of a cursor.
When i do D&B, I never see the area affected by the brush and this is annoying me. I don't know if the brush size fit my needs. And I cannot be precise (which area will be affected when I use the pencil?)
I know that iPad doesn't have a cursor as I have on my desktop, but it would be nice to have a button that once you press it, the Apple Pencil doesn't draw anything, but just moving a cursor on the canvas.
When I release the button, still showing the cursor, I start to draw, as well as I do right now.
Sorry for my english.
lucarubino reacted to MartinsRibeiro in Create manually Frequency Separations layers
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
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.
