In this Blender tutorial I show how to use the node editor to add a vignette to your images using an ellipse mask, a blur and a mix node set to Multiply.

Thanks - this is a very helpful tutorial! One thing to mention to people is to make sure to set your render resolution percentage to 100% in the Render Properties panel. If it's not 100%, the mask and gradient don't work well together.
Thx... and yes, your are right with the 100% resolution, the default is 50%.
I've probably seen a dozen of "How to add a vignette with Blender" tutorials, and yet no one is smart enought to just use a god damn spherical blend texture, which is still the simpliest and FASTEST solution. C'mon guys, it can't be that hard to figure
Well, the simpliest and the fastest is not necessarily the best solution. Remember what Einstein said: "Everything should be made as simple as possible, but not simpler."
It's not the case
Compare the flexibility of the parameters of an elliptical mask to a as you called it "god damn spherical blend texture", then you will realize that it is the case:-)
Well, yeah. That's the point - procedural blend texture is much more flexible
Take a look at this screenshot. With single texture node i can scale, offset, tint this vignette, make the edge harder with ramp, switch interpolation types, add few more color stops (if i want to, for some reason), and finally unlike blur approach - generating procedural gradient will always be faster.

Ok, I thought you were talking about an image texture. Well, it's nice but do you really think it is so much faster and more simple to go this way?
Couldn't be simplier than creating one single node. And as for speed - yes, and it's not just 2 or 3 times faster - it's a few dozens time faster, unsuprisingly.
