basing on previous years, inside your CD/DVD should contain the following
RAW - for verfication that there is no SUPERIMPOSING
JPEG - edited (will be used for FINAL PRINTING if it's a winning photo)
Editing is acceptable as long as it is applicable to FILM EDITING. Such as DODGE & BURN. CROPPING, EXPOSURE.
Technically, there is no SHARPENING on film. Some entries were disqualified because of excessive sharpening.
BUT BUT, some winners, most winners are EDITED JPEG.
So what the heck! Edit your photos as long as it's close to the RAW file. hihihihihihi SINULOG FOUNDATION has weird sense when it comes to RULES & REGULATIONS.
