Why is Velvia leading you back down the road to perdition!?
What is the hassle with learning and doing something properly, which slide film can teach you, rather than pixel-peeping onto a false-colour screen and repeating the image 30x to get it right?? I would have thought life is full of hassles. Slide film doesn't rate a mention.
Let's oversimplify "slide" film: it's a long strand piece of cellulose acetate. Chemicals are impregnated on it at manufacture. When slide film goes to the processor, which must provide for
E6 (specifically for slides, NOT C41, which is for negatives), those chemicals are stripped away to reveal the latent image recorded by the camera during exposure. There is no reversal or peculiar shades of light and dark of the image like negative film. It is, for all intents and purposes, the finished image, which, when well exposed (I'm not using "correctly" exposed because all professionals have their own interpretations of a correct exposure) is very eyecatching and satisfying to look at (there are many uses for them besides projecting). Slides when cut into individual frames can be "mounted" (in plastic frames) or more commonly nowadays, unmounted e.g. one continuous roll of images from 1 to 36 (in the case of 35mm). If in a roll like this, you have to cut them into 6s or individually for archival mounts (chiefly polypropelene/card mounts). When finished, slides must be handled with care: they scratch very easily. Their beauty will be fully evident if you view them with a lightbox. I haven't seen a projector since Jesus played half-back for Jerusalem, so I imagine they are
very old school.
Ken Rockwell is good at making headlines about himself, though he does make some valid points about Velvia. There is something you need to grasp: all active professionals using Velvia have their own methods for using it, and it is the gold standard for professional imaging. What you see on KR's website is NOT necessarily representative of Velvia on a global scale. What really matters is you getting out there with a few rolls and
finding out for yourself, through actively exposing and experimenting with it, how it best fits your needs. If you don't like it, then go to the alternative. But APUG is not the place to discuss all things digital. That's for the sister site, DPUG. And yes, you should
take notes of your exposures when you are starting out so that you can reason and understand why problems are occurring and what you can do to correct them by referring back.
