Finally, I found my film!

Hello everyone. First post here.

 

After trying out a few films, Fuji films only, I have finally found

a color negative print film that can render my outdoor nature and

lanscape images to its best and most natural appearance and colors

and detail. The FUJI NPS Pro 160ISO. I would just like to mention

that I shot 5 rolls of this film and I was impressed. I exposed the

film to 125 Iso. I think that is called "pulled the film" but I do

not know how many stops because I still do not understand the

concept of stops in film.160 -> 125. Not like stops in

lenses "f/stop"

 

Anyways, great film, the greens and blues are amazing.

Giorgio,

 

You did not pull the film. You just used an exposure index (EI) different from the ISO rating. Basically, you overexposed the film. Color Negative films are very tolerant of overexposure. It does guarantee that the colors may be a little more saturated and the grain will be minimized.

 

"Pulling" the film involves shorter processing times, coupled with overexposing. Pulling is not often used, perhaps only to correct for exposure errors, or rarely to subdue colors and contrast.

 

For every halving of the rated film ISO, it is one stop slower. You shot the film at EI 125, or minus 35 from the rated 160. That is about half a stop over exposed. You essentially gave the film 1/2 stop more light than it needs, presumably by setting the camera to 125 ISO. Same thing can be achieved by opening up the lens 1/2 stop, or giving 1/2 stop more shutter time.

closer to 1/3 stop than it is to 1/2 stop.

EXACTLY 1/3 stop.

Giorgio,

 

Next time you use NPS overexpose it by 2/3 stops (or rate it at 100 ISO). Maybe you'll like the results better.

Actually, 127 ISO would be closer to exactly 1/3 stop.<P>

 

log(160/127)/log2 = 0.3332434

Acctually it is 1/3 stop, the film iso speeds go in 1/3 stop steps. The number isn't exact, but photography isn't very good at using exact numbers, shutter speeds for example: from 1/8'th to 1/15'th is considered 1 stop, but the precise number should be 1/16'th, 1/500'th would be more like 1/512'th, but that's splitting hairs more than will be measurable on film, so we don't do it, it's pedantic than is remotly helpfull....

I thank you ALL! Great help.

I agree with James; can't let anyone get away with an "exactly" (especially if its in all caps) when its not exact. <BR>

ln(160/125)/ln(2) = 0.35614381022527530425936114102131

slightly more than 1/3 stop; but not 1/2<P>

 

Also, when you overexpose by 1/2 stop you are giving the film about 1.414 times as much light (41% more light), not quite 1.5.<P>

 

However, you are overexposing by ~.356 stops, which is EXACTLY 1.28 times as much light (and 1/3 stop is 1.26 times the amount of light.)

Whatever floats your boat. I use NPS 160 strictly for baby pictures because of its washed-out colors. Wouldn't dream of using it for landscapes. Portra 160VC, now that's a landscape film, if you haven't tried it you ought to.

Sorry, I don't touch no Kodak Films or Paper. I'm ma not a Patriot. I can accept that imports are and can be a better product.Canadian here.

Have a bowl of peat moss for dinner.

Tickle tickle, whats a matter. The truth hurts eh?<div></div>
