What would make a larger & sharper enlargement, Slide or Negative?

[BKSinAZ]

Lets say that you took two identical pictures of some subject (ether portrait or landscape), one on slide and one on negative. Both have the same iso. What would make a larger & sharper enlargement if I decided to frame the picture?

Ok, let me ask another question that has nothing to do with the first question, which would you use for portrait if your goal was to enlarge, slide or negative?

Some may feel a picky need to argue here, but IMO, if sharpness is your only criterium, both negative and slide film are equal...

I would say say an image from a slide would appear sharper. Note the "appear".

Generally slide have more contrast, saturation and punch. I find they're better for killer, graphic images that you want to put on the wall. However if you're talking about shadow detail and subtle colours then you're better off with negative film. (I usually do landscapes on slide film and people on negative).

Comparing this year's Reala and Provia 100F at pixel level - I pass. The only set of pictures that looks less sharp was taken on a lens that I know to be less sharp.
