Here is how this was done
Epson 4870 flat bed scanner set at about 600dpi,lid up….Make sure the glass is spotless other wise ist is a bugger to clone all the dust out. turn the flower or what ever you are going to scan face down.You have to think backwards some times when you are doing a collection of different items. You can play with curves before you scan that helps in post.Add a little sharping,contrast and color and you have a different image. keep in mind that scanners have a very shallow depth of field,so dont get frustrated it takes time a whole lot of playing.
