Fast Adjustable Vignette - Gimp Tutorial

I sometimes want to put an artificial vignette on photos that I have taken, but I could not find a fast way of doing this until while still being able to adjust he parameters quickly... until now.

Very brief instructions:

• Create a copy layer with a mask
• Use the radial blend tool on the mask from centre of interest point to farthest corner of photo
• set top layer to be subtract (or maybe multiply)
• Use curves on the mask to make sure interest point is not vignetted at all and adjust curve for pleasing vignette effect.
• You can double the power of the efect by simply making a copy of the vignetted layer.

Detailed instructions:

• open the photo in Gimp and make a copy of the layer 

• add a layer mask to the top layer

• Select the blend tool and make sure that the "Shape" is set to "Radial"

•  Making sure that the mask is selected drag the tool from the centre of the photos important part to the furthest corner of the photo.

• Change the Top layer "Mode" to "Subtract", you can also try some of the other options here for intersting effects such as "Burn"

• To modify the vignette:
• Use the curves tool to specify the area excluded from the vignette and also the rate that the vignette is graduated.
• If you can't get the effect powerful enough for your liking (more noticable with other effects like multiply) then you can create a duplicate of the vignetting layer and it will double the power of the effect
