I right click on the layer and click on Blending Options.
I then checkmark the Drop Shadow options and highlight by clicking on it.
After that, I set my opacity to 75-100%, sometimes less depending on the quality of the item. Items made with better quality are easier to keep at a higher opacity.
My Distance, Spread and Size depends on what I'm shadowing.
My Spread is almost always a 0.
Here are the settings for the following items:
Papers & Photos: Distance at 8, Size at 15...I then play with my opacity as I said earlier, because the quality of the paper depends on how realistic the drop shadow looks. Sometimes the shadow needs to be toned down a little.
Elements: Distance at 13, Size at 21. If it's bulkier, I may bring it to 18 and 21, or 18 and 24...I just play a little to see how much POP I want from the element off the screen.
Acrylics: I usually use Distance 13 and Size 21 but I switch my Blend Mode to "overlay". Again, with acrylics, the opacity will need to be played with depending on the size and quality of acrylic item.
Thats it! No extra layers or anything! I love my method and I like the way my drop shadows work. Plus I can shadow each item as I go and it really takes NO time!
If anyone uses my method I would like to see what you think of it.
