Hi there

having used PV2, I have notice that for the same file, B5 provides a different rendering of colors, especially Blue, than other programs (e.g. B4, ViewNX, DxO or even Lightroom) for the same white Balance setting.
Basically, there is a light green cast in the skies that I don't like. Plus I very much like color rendering provided by ViewNX.

Fair enough, I can understand that different software render color differently, but I also would like this to be configurable,

e.g. the same way as the "Camera Calibration" setup in Lightroom, with a set of predefined profile, per Camera.

Is there something planned that provide a similar feature ?
Is that what the "look profile" is for ?
Is it planned to deliver a set of predefined "look profile" per Camera manufacturer or model ?
Will there be a possibility to define one's own look profile set ?

Regards.

Do you have a sample? I have no problem with skies with my D90 NEFs.

I haven't notice this kind of problem also.

- Do you load an icc profile in your softwares' settings, and maybe not in B5?
- Have you made a "save as raw default settings" on a picture on which you have change something?

See here attached an example.

On the right : B5 PV2, "Everything off" preset applied

Well, that just looks like the regular difference between raw converters to me.

So ok.
Let's assume this is indeed due to different raw converter interpretation.

I don't mind.
But any chance we can tune this interpretation thanks to Camera profiling for instance ?

You don't want to profile a camera yourself unless you work in a constant environment. B4 had custom camera profiles that rarely anyone ever used, I suspect they will show up in B5 sometime in the future.

In contrast to various other product, Bibble has profiles for each camera it supports.
Now if you like the NX rendering better, I would think it is just a matter of setting up the proper defaults.
The NX image basically looks a bit more saturated and contrasty.
That should be easy to fix and then save that as your raw defaults.

cheers

I didn't find them (custom camera profiles) in the b4 documentation - are they described or explained anywhere? Or just a hack?

Check the CM tool Wink
I don't think there is much documentation on it, there was a bit of discussion in the B4 forums on this.

cheers

In fairness, you did mention "You don't want to profile a camera yourself"; but didn't note, if you insist on trying - advanced degrees in computer science & ee might be a sensible starting point. Laughing

Think I'll wait...

Hi there

Ok may be "Camera profiling" was not the correct term.

I was refering to the "Camera profiling" section of Lightroom interface, where you can configure slight color adjustments so that the Raw file interpretation suits what you want.

I would love to have similar feature in B5.

PS: I do have PhD in computing science;
But i don't want to re-develop the software. I'am just a user.

Set up an image that reflects your color preferences and then right click on the thumb, settings, save defaults for this camera type.
Quite easy.

cheers
