while scanning some film negatives - i edit the orientation and the color correction of each slide in iphoto- is there a command i may have missed? I can only do the rotate command. In preview app -i found the "flip horizontal" command but when i save the changes i've made- it didnt save the new orientation. What am i doing wrong here? i choose these 2 app because its easy to manage- specially in group editing. But if you have any app to suggest please do so. Thanks in advance.
