From my photo experience for over 40 yrs shooting, and now with the Hasselblad 503cw/PhaseOne P45+ back, you always want to shoot RAW. Lightroom or Capture One are great editing programs, then exporting to Photoshop for further adjustments; 'spot healing', crop, curves, (if necessary) image size, file type (Tiff, Jpeg), etc.
I guess if you want something light, a simple point and shoot will give you a memorable moment, but if you really are doing anything professional, a great lense, ideally 20 mp @ 6um or larger (if shooting digital) is the minimum I would use (although I still love film !!!). A tripod is a must, as well as a release cable and 'mirror up'capability (although not necessary). Obviously, this is a large and heavy medium format setup, so not for the guy travelling light, but, even if you are shooting 35mm w/ telephoto the tips will still apply.
