So my mom is running her iron man today and I'm dong the pictures with my FM2. Unfortunately, my zoom lens is really dusty (maybe inside?) and the mirror itself has gotten a bit dusty after a stupid experience in a concert. WHat should I do to fix this in the meanwhile as I have only a few hours before my next opportunity to take some photos and I don't have access to any professional cleaning stuff. The camera stores aren't open yet, either. Also, some of my photos already have some dust on them. I got as uch as I could out, but does anyone know about editing out dust specs in photoshop? What should I do? -any help would be greatly appreciated -thx!
