I'm wondering if there's any good and EASY program to remove dust spots? Currently I'm using Canon's Digital Photo Professional and there is tool to remove them but because there is no contrast changing like we have in pre-screening tool you must work on normal picture which makes job extremelly hard. I need to watch for dust spots at the pre-screen tool on Jetphotos queue then compare potential dust spot like "OK, left from cocpit, height of the tcas antenna" and then I'm trying to find that on real image at DPP. Photoshop is too expensive and some other programs are just too complicated, I need something simple and easy only to remove these bloody dust spots as everything else I'm able to do with DPP.
Can you help me with that? I tried to google that but all results give me some hi-end professional programs that cost fortune and they are too complicated

Best regards,
