Welcome to the forum, Terry
...image quality is too poor for an exact analysis - however if reproducing these shots i might try the following:
Image 1:
Studio location / cross lighting on background, lights +2 fstops from camera setting / key (main) light @ 4.00 o'clock, 45 degrees, large soft box, fstop same setting as camera / fill light with soft box between 6 & 7 o'clock and 45 degrees, -1 fstop from camera / lens - maybe a 50 or 70mm
Image 2:
Looks like an available light photograph - using fill flash from on or above the camera / lens - maybe a 35 or 28mm
The Soft Affect:
From these shots i cannot ascertain if this was achieved, either, through the lens, lighting, post production in photoshop - or simply my fuzzy screen
...i am not familiar with your camera nor the Canon system and cannot advise on the settings and accessories you require
However, hang about, someone else may be able to give specific advice - or you may learn a few things from reading other posts and asking more questions...
Cheers!
