Convert for Smart Filters and other Photoshop stuff
Hello,

I am following a tutorial to make a photo look vintage. However this tutorial is for Photoshop. I was positively surprised to find out that many of the options in the tutorial are also in Gimp. However there are something I could not find and I am not sure if this is because they are named differently or else because they are still not there.

The first thing I did not find is "Convert for Smart Filters". In the tutorial it says using this "you can apply filters to the photo while leaving your original in tact. It's a non-destructive way of applying filter effects, as you'll be able to adjust the filters you've applied at any time. First you'll get a message saying the layer will be converted into a Smart Object.".

Another thing I could not find is "Vignette" and "Midpoint"options in Lens Correction (in Gimp I found Lens Distortion) window. Do these exist in Gimp? or can be created with some other filter?

RE: Convert for Smart Filters and other Photoshop stuff
There aren't that many ways to edit images so Gimp and PS have indeed a lot of functionality in common. However as far as I know "smart filters" have no Gimp equivalent.

I don't know PS but I suspect that "Vignette" is merely darkening the corners. There are several ways to do it. Basically you do a fuzzy selection that leaves out the corners and some border: round rectangle, ellipse (border can be about 10% of the picture size), then you "feather" it (about the double, 20% of picture size). Then you invert it (so what is selected is the outside). You can then use use the levels tools to darken that part. If you want to also lose contrast/detail, you add another layer, bucket fill the selection with black, and adjust its transparency. You can also use the selection to apply a light focus blur. You can of course mix all these effects.

Good tutorials don't tell just how do do things, but also why they are done that way. This makes them easy to adapt to Gimp from PS (and vice-versa).
