The main effect is on the strong primary colours that are reflecting high UV, which seems to make them "scintillate". The rest of the colours are less affected.

Take a look at the response curves on the data sheet

Chuckle....... try a reliable 3.4 stops with V50. Brightest highlight (white) that you want detail is +1.7. For some colours you can squeeze out a fraction more, anything below -2 will be jet black. Its very hard to scan anything below -1.7 unless you have a drum scanner.

footnote - should have added that this is spotmeter off the tone.

I assume you mean -/+1.7 from the "middle grey" exposure value, correct? Anyway, I didn't expect the dinamy range to be so narrow... :shock:

If you want more dynamic range, Velvia 100 will give you 4 stops reliably (+2/-2), Provia possibly 5 stops but Astia can give you up to 6 stops and a much more natural colouration - if you can find it to buy :?

I forgot to ask.....

Joanna, can you still get Lee filters at the discount rate?

If so could I order a 100mm resin 2c filter via you?

Steve, you can certainly order through me with the usual 15% discount for UKLFPG members. Unfortunately, Lee have closed for the weekend, so I can't tell you how long the lead time will be until Monday.

Yes. Process I follow - if you meter off white snow or a white cloud and want to hold detail then spot meter off it and add 1.7 to the reading. If there are no such highlights and there is dark shadow that I want detail in then I place it 1.7 stops below the spot reading from that point. For both of those options I will then check where important tones lie and grad or whatever accordingly. Equally find a mid tone and all that will register reliably on film is +- 1.7 from that reading, again adjust according to how you want the slide to look. The key problem with V50 is that you can get more shadow on the lightbox but it is such a rich shadow that the V700/750 wont punch through it.

From memory V50 blows blue first and so if you are photographing a predominantly red/yellow sunset then you can push it to +2 or even a shade more. This is a quote from Tim Parkin
However, the feedback I got from Joe Cornish was that it really is a long subject which needs more than a quick response but in short, Velvia 50 responds well to reds and yellows and not so well to blues and cyans. This means that when you take a shot into the sun, you can get texture up to +2 1/2 and colour up towards +2 2/3 to +3 .. Cyan and Blue however start to go clear at +2 1/3 and if you want texture, you need to be using +1 2/3.. Wow! Something I think will be very useful. At the bottom end, the feedback is that Velvia will record black detail down to -2 2/3 (although you need a drum scanner to get it out) and -3 will go hard black.
My own experience over 10 years of using V50 (old & new) is to stick within +- 1.7 and only stray outside of that if I really really have an exposure conundrum and another film choice isnt an option.

Valerio, I've been a very long time user of V-50 over the years in 35mm-6x7cm-4x5. I was totally lost when Fuji dropped V-50 years back now and I tested the alternatives of V-100, V-100F, Provia, & Astia. Using quicklaods at that time made it very easy to shoot one of each in a short period of time in the light transition at dusk & dawn. The fact was they all had strengths and weaknesses. However, I was one very happy camper when the real V-50 returned to the market. Maybe it's just me and having used it so long and know it's up's & down's, but it flat works for me and my type of shooting.

@Dave: thanks for the clarification.

@Trail Images: thanks for sharing your point of view.

At the moment I haven't decided yet which film I would use, but it'll probably be V50 or V100. We shall see! :D
