Velvia 100 compensation

Charles Pezeshki wrote: Hi Folks, Just bought a bunch of Velvia 100 and am headed to the North Rim of the Big Ditch to shoot it. I used to shoot Velvia 50 at around ASA 40 in the SW. Should I compensate for Velvia 100 and shoot it at around 80? Or does it meter true-to-form? Best, Chuck http://www.wildcountry.info Chuck, I did some basic testing and convinced myself that it was accurate at 100. The few magazine review articles that I've read on Velvia 100 also confirmed the same. I now use it instead of the 50 (which I definitely had to expose at 40), and I've been very happy with the results so far. The only down side it the cost premium for the 100. Claude |

Velvia 100 compensation
In a case like this you also have the option of doing a "snip test".
This may seem like a very "amateur" thing to do to some of those who have a very empirical approach to their photography, but I've worked on commercial projects where, no matter how pinned down the variables were, a snip test was routinely done to ensure that everything was going to come out right. Basically, this means running a few frames "snipped" off a roll of 35mm through the processor to see if it is, in fact, spot-on or if an adjustment in processing would help to produce the optimum results. In the case of medium format you may have them snip off some film or just shoot a whole roll of typical subjects that you can afford to sacrifice (it may not be a sacrifice - it will probably still be usable). For LF it's easier...just run one or a couple of sheets through. The cost of doing this and any additional costs that you may incur for adjusted processing is a small price to pay for the "insurance". Review the results and ask the lab to make any adjustments that you feel will produce your desired result. I've had the advantage of doing this with both Ross-Ehlert and Gamma labs here in Chicago and it has always worked. Again, this may seem a somewhat slipshod way of working to some, but think about it...when the expense of setting up a shot or a session or the expense of traveling to a location is the big cost of the shoot, it can be a very valid way of working, argon |

Snip tests are commonly done by professional photographers on commercial
assignments. There is nothing amateurish about them at all. steve simmons |

"No One" wrote in message ... Most of my equipment is new, and meters correctly. My lenses are also new or relatively new and spot-on. I don't have time to test. It was relatively well-accepted that Velvia needed to be slightly overexposed. My question is regarding the new Velvia 100. What have folks found? I have found that using untested film on an odyssey is a foolish thing to do. Laughably so. Do you feel lucky? No test shots is a real risky deal. BTW, I would take some Kodak E-100G. Velvia's main problem is color fidelity in thedeep red/purple spectrum, where it stinks. |
