V1 colour tweaking
 
The V1 picture has beautiful colours, with reds and greens rich and juicy - especially in cinecolour mode. However, tweaking it is a bit limited - with only 2 parameters available: hue (green vs red) and WB shift. What I'd like to achieve is some more blue sometimes, so that he sky is deeper blue, the distant woods seem bluish rather than greenish, the snow with blue reflexes, etc. Of course, one can add some blue cast with WB shifting, but this makes the picture cold - and I'd like it to stay warm, with whites still white...Is it possible at all?

I've tried all combinations of hue shifted towards green and WB both colder and warmer and got some beautiful results; however could not recreate this nostalgic, green-blue cast on water and sky and land, and even the air...

Any suggestions?

Why not try a UV-filter?

Would also protect your lens front

Why not do most of your color correction in post? That seems to work well enough for me.

Ha, ha - when writing my post, I should have added:

Any suggestions, other than filter and post?

Thanks, anyway:)

Max, is there a filter kit (or just an UV filter) that fits the V1 with the lens hood/lens cup still on?

Piotr,

I have a friend using a Z1E

He keeps the UV-filter on, all the times.

(Übrigens filme ich konsequent immer mit einem UV-Schutzfilter (zum Schutz des Objektivs).

UV-filters, as you might know, will give you a much better structured and “darker” blue sky, especially if there are some white clouds around

I tried to order a packet of filters and a .65-WW-adapter from “schneideroptics”. (ex-century) They will have the V1-line ready in 60-90 days. In this packet I have included a UV filter. But I had no chance to test it

Thanks Volik, but this doesn't answer my question: which solution allows for permanent UV filter and the lens hood/cap(shutter) on the camera?

I also have one more doubt: do the outdoor (daylight) WB preset shift (-7 to +7) add to that already in the picture profile, or are they exclusive. Suppose I'm using a PP with WB shift =-7; when I shoot with AWB=outdoor preset-7 (on the dial), will the resulted WB shift be -14 towards cold (blue)?

All UV filters that are thread-mount will go on the lens with the hood intact.
You never want a UV filter beneath your wide angle adapter.
There are different grades of UV filters, you get what you pay for.

I've just experimented a bit and it seems they actually do add! With WB shifted all the way left (cold) in PP, turning it down with the dial (with daylight preset on) makes the picture even colder (almost monochrome), while turning it up towards warmer values ends up with a more or less neutral temperature (-7 + 7 = 0). Can anyone confirm this?

Spot,

Thanks for your hint. Which UV filters are recommended for the V1?
