I don't know if anyone can use this - but I thought I'd share:
When I first started - I'd go in and type my 'name + photography' across EVERY image... to keep someone from 'borrowing it'.
I found a tutorial on how to do a brush preset - and holy cow did it shorten up some of my time.
I created a brush preset so now I just 'stamp' my logo on a seperate layer, and presto. To me, this seems like something everyone already knows, so if you get anything out of it, let me know! ;-)
Create your logo on a 5"x5", 300 pixel resolution. You want the background layer to be transparent. Do the logo large enough to fill that 5x5 (or whatever type of size your logo needs) area. Don't use a 10sized font... you want it large.
In the sample - I used sizes 52 and 48 fonts.
I do everything in layers, cause it makes it easier to work on (aka fixing my screwups!)
Once you've got your logo like you like it - crop off all the extra space you don't need.
Once you've cropped your logo - go up to EDIT, and down to DEFINE BRUSH PRESET.
A little box will come up - type in: LOGO BRUSH
Open up an image.
Click on Brush - and go to your brush list - the very last brush in your brush list should be your new brush you just created.
You can make the brush smaller/larger by pressing the { or } keys... or by using the slider in the brush selection area.
Stamp your image:
For posting to web - I always resize/sharpen for web - and then brush my logo on.
Hope this helps! ;-)
