wgphoto Posted May 5, 2016 Share Posted May 5, 2016 Title may be confusing so let me explain. I use a method of adding grain to my images that I learned in a photoshop tutorial. One of the steps for this method requires me to resize a layer by a factor of 2 to make the grain larger than the original canvas, thusly making the grain appear coarser. As you might guess, leaving this extra info there balloons the files size quite a bit. The next step in photoshop would be to crop that extra info outside the borders of the image to the dimensions of the image, while still leaving the grain larger/coarser. I'm neither a photoshop or affinity photo wiz, but I can't figure out how to do this in AP. I'm sure it's simple. Thanks in advance for your help.

A_B_C Posted May 5, 2016 Share Posted May 5, 2016 You could select the enlarged grain layer in the layers list and choose Layer > Rasterise. This will remove the excess, but be aware that you will convert your layer into a pixel layer by doing so … :) Quote Link to comment Share on other sites More sharing options...

This will remove the excess, but be aware that you will convert your layer into a pixel layer by doing so … :) Since this layer started as a pixel layer that was filled with 50% gray and had noise added to it, isn't it already a pixel layer? BTW, can you transform by percentage instead of doing the math to figure out exact pixel count? I know this is a default option in PS Quote iPad Pro 12.9 M1/Mac Mini M1, in that order Link to comment Share on other sites More sharing options...

A_B_C Posted May 6, 2016 Share Posted May 6, 2016 Yes, then it is already a pixel layer … so rasterising does not affect the layer type … :) https://forum.affinity.serif.com/index.php?/topic/19770-rasterrasterizerasterise/?p=91891 Quote Link to comment Share on other sites More sharing options...
wgphoto Posted May 6, 2016 Author Share Posted May 6, 2016 Ok, one thing to keep in mind for anyone trying to do this in the future. If you add noise by applying a live filter, once you rasterize, you lose the point of a live filter as it gets baked in. I wonder if there is another way to crop off this excess without rasterizing.

A_B_C Posted May 6, 2016 Share Posted May 6, 2016 And you should also have in mind that scaling a layer with a *Live* Noise Filter applied won’t make the noise grain coarser … ;) Quote Link to comment Share on other sites More sharing options...
