In a bid to make this MF forum more informative and user friendly to other MFrs, I thought I might post items of interest that I have posted elsewhere that might be useful to others. If other MF'rs wanted to add any little write up's on techniques or experiences with testing films, metering, anything at all, to help others attain certain results, perhaps here might be a nice place to start a technical stream...
---------------------------------------
Velvia Push One - results...
Equiptment - Mamiya RB67 Pro-S
Lens - 127mm Sekor C
Filters - 77mm Polariser
Metering - Sekonic L-358
Tripod - Linhof
Film - Velvia rated 100
People often have questions and queries regarding Velvia pushed to 100, here are my own results. I usually rate my velvet @ 40, either that or my E6 guy will do it anyway, which gives it a 1/3 push. Effectively in development time this was pushed 1 and 1/3 stops to get my result.
Conditions- Time was about 9am to 11am in bright sunny/somewhat hazy day, clear blue skies, along lush waterfront with allot of opportunity for contrasty light. I was shooting from cliff tops and banks that shouldered the harbours edge most of the morning.
Subject- Boats, shimmering blue harbour water, blue skies, some framed foliage and close up on shrubbery in dappled shade.
Ten shots on the RB with the Velvet pushed 1 and a 1/3 in development under the above conditions yeilded superb results! There was little or no discernable difference in grain where clear sky was not featured. And many of the images that had prominant sky held a deep rich blue where the Polariser had done it's work. The haze on some of the other shots could not be countered by Polarisation due to incorrect angle to the sun and suffered a contrast blow out as a result of the 1 and 1/3rd push.
Shadows held detail and even though contrast was up overall it looked real purdy to both myself and my E6 guy who preffered the effect on the greens in a deep-shade, shrubbery and ferns, shot I took. Overall I would not fear pushing this film to 1 and 1/3 in future but wouldn't want to go past this point. I only got the Velvet pushed because I forgot to change the ISO on my Meter after shooting T-max 100 the day before...arghhh! But I am damn pleased with the results of the push and can clearly see an artistic place for this kind of treatment of the Velvia in future.
Pro's - Damn nice having that extra stop to play with. Even on the deep shade shrubbery shot I took I was at 1 sec at F/22 with the Polariser on, this was compensated to open up after an initial metered average taken on the Sekonic memory and average function. I have found this function to be really handy in just these close up, dappled light situations where you can get four to five different values in a space of one foot of greenery. Can also make your shots take on a different tone, try it and see.
Cons - Loss of contrast control in sky values and a slight bumping up of your base values also. No noticeable colour shift from what I could see and I got away with great results in very tricky and contrasty lighting! It's all good really...
Hope this is useful to somebody or anybody who makes this mistake or who is just curious in future to know what they might be getting.
