Re: [Leica] OT: how to do somethingin Photoshop

[Johnny Deadman <lists@johnbrownlow.com>]

various ways to do this but here's the simplest

draw a lasso around the area around which you want to burn in

1.	choose select--> inverse (now you have selected everything but the 
center)

2.	choose select-->feather selection and dial in a radius, try 250 
pixels and work down if that's too gentle. (This makes the edge of the 
selection a gradient rather than a hard line)

3.	choose image-->adjustments-->curves. Make a point right in the 
middle of the curve and move it up or down. You'll see the edge of the 
frame darken and lighten. You can now dial in however much tonal 
adjustment you want. You could also use image-->adjustments--> levels 
and move the centre gray slider left or right but I prefer to work with 
curves.

variations on this

In step (2) repeat the 'feather' step to achieve even gentler gradients.

In step (3) use layer-->add adjustment layer-->curves to add a masked 
adjustment layer which you can alter later (this is how I would do it, 
but you have to be in 8-bit mode as you can't add layers to 16-bit 
images).

hope this helps
