How to make a lomo vignette in photoshop... one way to do it

First of all, open a photo you want to add a lomo vignette to

1. Go to Layers - new fill layer - gradient...

2. Name it lomo - click OK

3. you get a window up there:
Style: Radial
Reverse and Align with layer should be checked.

3. Gradient: (image 01) As seen in image 02, choose forground to transparent. Left color stop should be black and white in right color stop. Left Opacity stop is 80% and right is 0% ( image 02)

4. Change the layer to overlay (image 03)

You got a lomo effect, you can play with the numbers as you like, and somethimes I erase part of the lomo layer if it´s too dark at places I want to be light. Like in this photo, I want the lower right corner to be light, cause I like the marks in the sand.

*TIP* I use a soft brush and often with 60 - 80 % tranparent to erase parts of the lomo effect.
