Tareq, that's a lot of questions. I'll have a stab at a few.
I haven't done any colour processing but from what I understand it's much more precise (with no room for error) than black and white processing, which allows you to experiment with dilutions, agitation, chemicals, etc. For colour it's almost always the same -- you can't really change the process of development (for the most part). In addition, if you get an enlarger you would need one that could do colour, as well as getting another set of chemicals for the paper. Black and white is a separate process (film, chemicals, paper) entirely -- from colour. The only exception would be chromogenic black and white films like XP2 that can be processed in colour chemicals.
As for process...it's really the film that makes a difference, not the process. There is a difference between slides (positive film) and negative film as well. If you want prints, go with negative film (like Ektar, Portra, etc). If you want to project slides, or maybe only scan them, then you could try positive film. You can cross-process slide film (E-6) in negative chemistry (C-41) but the look will be different depending on what type of film you use.
Film used to come in a great variety of sizes, but for the most part they now fall into 3 categories -- 35mm casettes, 120 (or 220) roll film, and sheet film. You're probably familiar with 35mm film, 120 film comes on a spool with a paper backing to block light -- it's used for medium format cameras and will produce different size pictures depending on the camera/back that you have 6x4.5, 6x6, 6x7, 6x9, 6x12, etc (that's centimeters). Sheet film is like a sheet of paper (but film), it comes in different sizes --4x5, 5x7, 8x10, and larger (that's inches). Each sheet is exposed and processed individually. Of course, the larger you go, the more expensive each frame becomes.
Hope that helps.
Not exactly. Sheet film is for large format. Slides are created with slide film, which is available in all formats from 35mm to 8x10. The film is processed as a positive, and becomes a "slide" when each frame is encased in a mount for projection.So rolls arAnd you say if only scan then go with positive, so negatives can't be scanned or not good for scanning?e for 35mm and medium format, and the sheet or slides are for large format?
No. Actually, negatives can be better for scanning, due to the inherent dynamic range of a negative. The advantage for positive film is that you have something you can visually compare the scan to, unlike a negative.And you say if only scan then go with positive, so negatives can't be scanned or not good for scanning?
If you have the same black and white film in two of the same cameras and shoot a scene/subject in the exact same way and develop in different chemicals, you could get different results. It depends on which different developers you use.
If you have the same color film in two of the same cameras and shoot a scene/subject in the exact same way, you should get essentially the same results no matter which chemicals you use or whether you take the film to a lab.
If you start out with DIFFERENT films but process the same way, then it doesn't matter if it's black and white or color. There will be differences, all films have some unique traits. How much you will actually notice those differences depends on which films you're comparing, how you scan or print the photos, and how you yourself see them.
Negatives can be scanned just fine, mooseontheloose is not saying that they can't be scanned. It's more that slides (positives) are a finished product that don't NEED to be scanned, and that slides can't be printed easily (without scanning, that is). If you want prints, go with negatives.

I like E100G and Rollei CR200. I am starting to adapt some of the Kodak Portra and Ektar every once and while. For 35mm I shoot the Elite Chrom 100 and 200.
I think i should see what is the slides or sheet and how they develop it, mostly by seen i can learn faster and understand more than i don't know what the items are, all what i know that negatives is that has to be scanned and processed to see the photo, or printed by a way to get the pics back out from the film roll or so.
