Fragenmeister knows how to ask questions.

You can do as one suggest and just roll it in the opposite direction and that will take a lot of it out. If the picture is good, you should get it matted, or at least put it into a folder where it can't roll up.

Part of your problem comes from the fact that the paper was rolled up. The second part of your problem comes with unequal co-efficients of expansion of the paper on one side and the coating on the other. You have the same problem with old print paper, it will roll up also. I have the same problem with pictures that go through a HP or even my cheaper, but better, Kodak printer when doing prints at home. Actually, you have the same problem with films like the Kodak or Fuji slide film. When put into a projector, they will "pop" and produce a curved surface. If they are glass mounted to stabilize them, they stay flat - so Kodak and other projection lens manufacturers make both Curved Field Lenses and Flat Field lenses. It is the same phenomon as with the paper, different expansion rates of the film and the emulsion

What kind of film can i use for my Nikon 65?

Hi,

I was wondering if i was able to use Fuji Velvia on my N65,i don't have a tripod so does it matter? And if i'm taking outside pictures i want my pictures to come out professional and the colors to be vibrant and less grainy... help!

thanks!



Answer
Hello Priscilla.

You can use any 35mm film you want with your Nikon.

Now at the risk of insulting you I have to ask this: You do know that Fuji Velvia is a color reversal or slide film don't you? No negatives and prints, just color slides which have to be viewed with a slide projector. If you know this then accept my apologies.

If you want excellent prints with negatives I suggest the latest from Kodak - Ektar 100. Virtually invisible grain and rich colors. Another good choice is Fujicolor Superia Reala, also ISO 100 like Ektar.

For landscapes I always use a tripod. Actually, I use a tripod whenever possible. If you do choose to go with the Velvia 50 then a tripod is highly recommended.

Here is my approach to landscapes:

1) Camera on a tripod and leveled.

2) 21mm lens at f16 and focused to 6 feet. This gives a Depth of Field (DOF) from 2'-1" to infinity.

3) A circular polarizer.

4) ISO 100 film.

5) Camera set to Aperture Priority. (I shoot in Aperture Priority 99% of the time. I've gotten old and lazy LOL!).

6) A cable release or the camera's self-timer to release the shutter.

For a good explanation of DOF plus a handy DOF calculator (you can compute DOF for any combination of lens focal length, f-stop and subject distance imaginable) go to: http://www.dofmaster.com/dofjs.html
