Yes 35mm, I use a Canon AE-1 with 100-300 zoom. how can you tell it was film.
It's a little grainy...and something about the color gradation... really shows up when you digitize and crop film images (I assume you cropped?).
I guess they could easily have been digital, but I guessed film, also.
Not that I'm criticizing... I like the look of film. What brand did you use?
