    Color correction for Rollei Digibase CR200?

    I actually finally got around to shooting a roll of Rollei Digibase CR200 a few weeks back. I had somewhat high hopes for this film, since I have heard that it is probably the closest E6 to Kodachrome. But the slides I got back were quite yellow. This seems to be rather common with this film, and is supposedly the result of the film being intended for aerial photography. But I couldn't find anything in terms of what people are doing to correct this yellow cast. Might some sort of cooling filter work? And if anyone has actually found a filter that corrects this yellow cast, what specific filter was it that you used?

    I've not heard it was for aerial- interesting. I have a high-altitude filter but it is a slightly warming filter.

    My impression is that most use this film and its CN companion for scanning... in which case shooting a color target and then making the necessary adjustments is quite easy. Why not shoot a color separation chart under the light you like, using your best guess filters, and take it from there. I'd be interesting in seeing your results, and some detail crops.

    If you liked Kodachrome then let me suggest Astia 100F.

    As I understand it, because Digibase CR200 was made for aerial use, the film itself was made overly warm so that no color correction filter would be needed when used for this purpose. However, I'm guessing some sort of cooling filter will probably be needed for it to look acceptable for normal photography.

    I've tried Astia. And at least to my eyes, it doesn't look much like Kodachrome. To me, it looks ALOT more like desaturated Velvia than it does Kodachrome. Of course, this is probably because it is made by, well, Fuji. I personally think E100G looks ALOT more like Kodachrome than Astia does. Besides, last I heard, Astia has gone the way of Kodachrome.

    Astia is still available in all sizes from Japan and at reasonable prices. I recently got some 220 that way.

    That's interesting about the CR200. Not sure why they'd bother making an aerial film at this stage though, I'll contact them and see if they'll sell me a bulk roll!

    As far as I know, it's an old Agfa film. So I figure it's something that was originally made decades ago.

    Maybe not old, as AGFA is still in the aerial film business.

    It's most likley AVIPHOT Chrome.

    Colour rendering
    A UV filter prevents colour shifts and unsharpness due to UV radiation. An interlayer prevents the diffusion of unwanted colour dyes form one sensitive layer into another. So, the colours are well separated and the colour saturation is very good. Aviphot Chrome 200 is suitable for a colour temperature of 5500K.

    From where are you buying it in 220?

    I just thought I would attach a couple of scans here. The scans are unaltered, and you can clearly see the 'yellowness' of the images. Notice how it even tends to turn the sky green in the picture of the tree. What's also kind of interesting is that the yellowishness is supposedly intended to counteract the blueness of high altitude shots. Yet both of these pics were taken at significant altitude (about 8000ft in the first, over 10000ft in the second).

    Matt:

    I don't think the colour cast in those is just yellow - I think there is a fair bit of green as well.
