Exposing Velvia
Any hints?
When using Velvia 50 in a lot of cases I find the sky gets burnt out but shadows are rather dark so stopping down is not an option. I am exposing to try and get decent detail in the sky and shadows. Any suggestions? Get a bit more radical with graduated filters perhaps? Note that I I'm not adverse to using filters I just don't like pictures that scream 'graduated filter' when you look at them. -- http://www.petezilla.co.uk |

Note that I I'm not adverse to using filters I just don't like pictures that scream 'graduated filter' when you look at them. I reckon Velvia 50 has the narrowest tonal range of any slide film I use, and if the range from highlight to shadow is too great in the scene, there's not much you can do about it. Some people expose Velvia at iso 40 to reduce the saturation, but this won't really help much with the high contrast, but try it and see: asking your lab for a 1/3 pull on such rolls _may_ help. I know one person who exposes at iso 32 with no pull, but he reckons this works with sheet film but not with smaller formats. I pretty much always use a spot meter to expose Velvia, so I can at least ensure nothing burns out, but this is often at the cost of a conscious decision to sacrifice shadow detail. Since burnt out highlights are so unattractive, this is usually the preferable way to go. If the only highlight giving problems is the sky (or some similar 'block' of brighter light) then the ND grad. can be the answer. To avoid the obvious look, I aim to select a grad. that will leave the sky at least one stop brighter than the foreground - ie. if there is a three stop difference, I'd try not to use more than a two stop grad. Since you are only trying to control over-bright skies, rather than produce a deliberate 'saturated sky' effect, a one stop ND grad. may well often be enough. Use the spot-meter to work out how strong a filter you need. (While Lee and Singh Ray both sell grad.s in one stop intervals, both will make them in half stop intervals too to special order.) You can also shoot two frames at different exposures and combine the sky of one with the foregrund of the other in PhotoShop. More work than using ND grad.s, but if the sky edge is too convoluted to use a grad. it can be an alternative. Other than that, try a different film... I find Velvia 100F has very nearly as much saturation as Velvia 50, but is a little less contrasty. You might get half a stop more range, so give a roll a try and see if it helps. Kodak E100VS is even more saturated, but emphasises different colours - it too seems to me slightly less contrasty than Velvia 50, though not by much. Peter |

(While Lee and Singh Ray both sell grad.s in one stop intervals, both will make them in half stop intervals too to special order.) I have a set of 3 cokin p grands in differing strengths. You can also shoot two frames at different exposures and combine the sky of one with the foregrund of the other in PhotoShop. More work than using ND grad.s, but if the sky edge is too convoluted to use a grad. it can be an alternative. Good idea, more work and not so hot for projection however.

It looks like I ought to be really chosy over when I shoot Velvia 50, or perhaps use another film as you suggest. Otherwise a bit of careful grad use, as you suggest. -- http://www.petezilla.co.uk |

Yeah - for that you need to shoot an extra exposure of everything... I expose Velvia at 50 and it scans _OK_ - not as easily as many films, but OK. But this is with a Minolta Scan Multi Pro, which is unfortunately an expensive machine. What scanning software do you use? I find Vuescan is good. I pretty much always use a spot meter to expose Velvia, so I can at least ensure nothing burns out, but this is often at the cost of a conscious decision to sacrifice shadow detail.

Use the spot-meter to work out how strong a filter you need. I was spot metering the shadows and sky and tried to pitch the exposure for the middle. With a lot of slide films you can meter the highlights and set an exposure up to 2 1/2 stops, maybe 2 2/3, below that without them burning out. With Velvia 50 I reckon you can't really go below about 2 stops under. That'll hold the highlights and give you about three stops down for shadows. If the scene's tonal range is more than five stops you can't keep both without a grad. If you are going for the middle, you may well be 2 1/2 to 3 stops below the highlights, and for Velvia this is too much, unfortunately. (While Lee and Singh Ray both sell grad.s in one stop intervals, both will make them in half stop intervals too to special order.) I have a set of 3 cokin p grands in differing strengths. Ditto. I have to say I didn't find the Cokin ones that great: they seem to me to have a slight magenta cast. For 35mm (and smaller Medium Format lenses) I've replaced my Cokin NDs with Singh Ray ones, which are extremely nice - but painfully expensive. I still use Cokin for the B&W contrast filters and some other things though, where they fine, and the price is much nicer. For most Medium Format I use Lee, which are also expensive, but do crop up on *Bay from time to time (those morons who sell them thinking that because they've gone digital they don't need filters any more - poor schmucks.) You can also shoot two frames at different exposures and combine the sky of one with the foregrund of the other in PhotoShop. More work than using ND grad.s, but if the sky edge is too convoluted to use a grad. it can be an alternative. Good idea, more work and not so hot for projection however. Yes, no good for projection, and it is a lot of work. Still, if you want to have a tree in front of a sunset, and not have the tree a silhouette (or blasted by fill-flash) it can be the only answer - on any film. Other than that, try a different film... I find Velvia 100F has very nearly as much saturation as Velvia 50, but is a little less contrasty. You might get half a stop more range, so give a roll a try and see if it helps. Kodak E100VS is even more saturated, but emphasises different colours - it too seems to me slightly less contrasty than Velvia 50, though not by much. Thanks for all that. It looks like I ought to be really chosy over when I shoot Velvia 50, or perhaps use another film as you suggest. Otherwise a bit of careful grad use, as you suggest. I am unlikely ever to go out with only Velvia 50 with me, because it is so picky. Usually if I am using it I'll have at least two bodies with me, more often three, with E100VS in another, and maybe Portra 160NC - which is very low contrast (but not a slide film, of course.) If I am taking only one film type, and it is slide, it is much more likely to be Velvia 100F than the original 50, but even then I wouldn't do that on a bright-sun day, where the contrast will tend to be high. (Since V100F came out I hardly use Provia outside the studio anymore.) Since you already spot-meter and use grad.s, I think you'll get this sorted out fine - it is just a metter of knowing that Velvia is very unforgiving! Peter |

I must admit I use Velvia 100F much more now, but 50 does still have slightly more saturation - a wonder for food photography, or an overcast day in the woods... Peter |
