I make no manipulation, other than crop. sometimes i change the brightness and/or contrast. i prefer the dada approach in terms all will understand: wysiwyg. my little $100 kodak does all right. it is one year old. i bet a new $100 kodak will have a lot more bells and whistles, but this is about as complicated as i wish to be about this.
can't wait until my studio is moved and i can really dig into some painting. for now, i will get some more epsom ink, some square panels and start mounting these. $50 for 5"x5" on raised panel. line 'em up and fill a wall. go for visual overload. stimulate some excitement.
