The single woman at the top was shot at ISO 1600 with a 35mm lens at f/2 at 1/30 second, while the trio was shot at ISO 1000 at f/2.5 and 1/85 second. Both shots are a bit underexposed, according to their histograms, but you know, both files have a LOT of "malleability" in them, meaning it's easy to lift the curves, and re-work the files a bit, with the files holding together and not "falling apart".
A few years ago, that type of malleability, as many call it, was not present in the JPEG images of many cameras...JPEGs used to be somewhat thin an frail,and you could not alter them much without the quality heading to Hades.
And yeah, I've noticed you've been picking up some first-rate equipment very rapidly...pretty soon you're gonna rival VI as far as top drawer Canon gear.
