My photography has evolved from B&W developing and darkroom work, to a decade of snapshots (young family), to (now) a nice Nikon DSLR, decent fixed and zoom lens, and raw files processed with LR4. I just returned from a trip to Ecuador and the Galapagos Islands. I have about 600 photos from 12 days of travel. My question: how does one cull such a large amount to 1/10 or 1/5 of this amount, a quantity I'll edit and maybe put in a book?
I suppose a first step is focus and exposure. If either of these is too far off (especially focus), reject the photo. Then there's the step of finding photos that just hit me, maybe 1 of 25 or 1 of 50. These I'll mark for further work. That still leaves a lot of photos to review and cull. What techniques or approaches have others used to decide which photos to keep for further work?
