At $695 RRP for Photoshop CS, perhaps you might want to consider Paint Shop Pro 8 ($79). It is a free download from
www.jasc.com (56Mb) and is time limited to 60 days. Thereafter you register and pay for the privilege.
It has batch execution of scripts (batch processing), it has scripts which seem to work the same way as PS actions, histograms, levels, curves, manual and automatic color balance, layers, masks, channels, supports PS plugins and so on. I have started using it very recently, and I have managed to recreate the popular PS photo enhancement actions (like Mandrake) in it quite easily. Gilligan has the process on his PT10 website. I will be posting the Mandrake filters scripts (like red addition and contrast masking) on the Board soon.
Download it, try it. You may be pleasantly surprised.
And... you can use the money you save to buy another strobe
Just my $616 worth.
Cheers,
Andrew
