Hallo, Photoshop-Users,
I´v had a look at this tip and I find it not very transparent to the user.
I´ll show you my way, to produce a fill-in-flash: (without owning a M6TTL!)
1) Make a COPY of the whole picture
2) Generate a new ALPHA-Channel
3) PASTE your COPY in this channel, it will turn to B&W
4) INVERT the channel
5) Make a GAUSSIAN-BLUR
6) Correct this channel in MASKING-MODE, if needed
7) CREATE a GRADIENT-LAYER
8) The menu of the GRADIANT-LAYER will show you a white frame.
9) COPY your ALPHA-CHANNEL to this white frame, which is a new (white)
ALPHA-CHANNEL
10) Lighten-up your shadows in the GRADIENT-LAYER
11) If you switch off this layer, you will see your original, situated on the
basic-layer
12) Save your file in PHOTOSHOP-Format. Make a copy as TIF or EPS, to import it
in a layout-program
If you want to make changes, open the PHOTOSHOP-Format and correct your
GRADIANT-LAYER, or your ALPHA-CHANNEL.
I find this way much more transparent to the user. It will not destroy your
original scan.
