TIP: Getting Good Results
I hate to be the guy that says, “Just drag the sliders around until it looks good to you.” But, I can tell you that I’ve used this filter enough to know that it
looks so different depending on the subject, that if you just drag each slider back and forth a couple of times, you’ll find a sweet spot where it looks good
for that particular photo, and you just stop there. It sounds like a cop-out, but honestly, that’s how I use it.
Step Seven:
The last control in this dialog is the Shine amount, and it controls how the light reflects: dragging its slider to the left makes your image very flat-looking,
and dragging it over to the right adds contrast to the highlights and shadows and kind of makes the paint look thicker, almost like it’s embossed. Here on
the left is the Shine set at 0.5, and on the right it’s raised to 3.5 (you can just imagine what it would be like if you raised it to 10, right?). Down below,
you’ll see a before and after with the original image on the left and then after applying the Oil Paint filter.
