X1 : Saturation

Chaps,

 

I noticed this with my X1. When I select B&W natural, the saturation menu doesn't work as I can't select it. It only happens in B&W and not under the colour mode.

 

Is this a firmware quirk or there is a problem with my unit?

 

Hear soon.

 

Thanks and cheers.

Saturation will only apply to colour images surely?

You could be correct but should it not also apply to the gray scales as well?

The gray scales are adjusted by brightness, contrast and gamma. "Saturation" means the intensity of the colors. You convert a coloured image to a B/W one by turning the saturation to zero.

 

Well, it's a bit more complicated than that, but that's the main point.

See, have you messed around with lightroom yet? I would try some DNG files and mess with saturation in LR... then convert it back and forth from color to B&W to see differences. Saturation can affect B&W for sure, but in camera it isn't an option that is associated with B&W.

Thanks Chaps for the feedback.

 

JS, I haven't manage to download lightroom yet but am planning to get a copy from the local Leica distributor as the bandwidth despite the broadband is killing. Will let you know in due course.

 

Happy shooting.

 

Cheers.

If you take a colour image, mess about with saturation then convert to greyscale you'll see some differences perhaps, but there's no saturation in B&W!

Hi, without doing any direct measurements I can't see any difference using your suggestions.

Playing with saturation in the colour layer, when you have a B&W adjustment layer on top (in Photoshop) makes a huge difference.

Maybe Andy, but if you start with a B&W file........?

Hmmm... maybe I'm mistaken then... but I could have sworn that it did. I though if you turned the saturation up and then converted it to B&W (by hitting the B&W button in LR), it would look different than if saturation was at 0 and you converted it to B&W (by hitting the B&W button in LR). Even if this did work the way i am describing, it wouldn't be a useful method.

If you change the saturation of a single color you do get an effect. For instance if you change the saturation of yellow, it is like adding a yellow filter on B&W conversion. (or a blue one if you go the other way) To complicate matters, you could also change the brightness of the color, creating a subtly different effect.
