Question

Drop shadows change in appearance when rasterizing

If you look at the images below, the first image is how the drop shadows look before rasterizing. This is how I intend for them to look. The second image is how they look after rasterizing (Layer-Flatten Image). The drop shadow is thinner than intended. 

I have tried making the drop shadow a layer but it still changes in appearance when I do that.

I have to export this image as a JPG and I want it to look the same as it does when it's a PSD.

I am using Windows 10, version 24.7 Photoshop.

Help would be appreciated!

When you say "Rasterizing" do you mean you convert you layer style to a separate layer via Create Layer or flatten the image?

Overlaying your two examples and changing one layer to Difference - I can see a slight variation in the shadow distance.

I have tried both creating a separate layer via Create Layer and flattening the image, the results appear to be the same. For the examples I specifically attached in my original post, the rasterized version was created by flattening the image.

I'm not sure if you were able to overlay the images exactly but FYI, both images were captured via snip+sketch so the positioning might not be identical. Not sure if that makes a difference for the image you produced.

I was able to align which is why you dont see the bone structure. Still can't understand why flattening would shrink or add depth to your shadow layer.

Are you viewing at 100% magnification/zoom level?

When I am zoomed in 100% and change back and forth, there is no difference.

When I look at the overall picture (which ends up being 29.7% in Photoshop) compared to the JPG in Windows photo viewer, it looks different.

100% view maps 1:1 - one image pixel to one monitor pixel.

 

Any other view will use interpolation (resampling using a quick and dirty algorithm optimised for speed, not accuracy).
