X1 jpeg with Adobe RBG

Hi,

 

I generally do not like to do a lot of post-processing, so I prefer to use jpeg output. I have been messing around with the jpeg settings and have found some that I really like (vivid mode with mid-low saturation).

 

However, in comparing the DNG output to the jpegs in a multiple different modes, there is definitely a different color "look" to the DNG photos. One thing I notices is that the DNG's use Adobe RBG color space. When I change the jpeg color space to Adobe RBG in camera they end up looking much more similar to the DNG, especially the indoor white balance (and the Standard mode jpegs end up looking significantly better IMO).

 

I am using Aperture 3. Are there issues with using Adobe RBG jpeg files? Printing, flickr, etc.

 

And on another note, why are the X1 DNG files so huge? I would think they would be around 12MB due to the sensor, but they are more like 18MB...

 

Thanks,

Stuart

Raw files don’t really have a color space but a raw converter can save converted raw files in many different color spaces, Adobe RGB included.

 

If color management is set up correctly on your computer there should be little difference between images in different RGB color spaces.

They would be 12 MB if the X1 was using the same lossy compression scheme the M8 and M9 (optionally) uses, but the X1 doesn’t.

Thanks. I think by turning onscreen proofing mode on in Aperture and setting it to sRGB the issue DNG's and jpeg's now look more similar on screen at least.

I have always used Adobe RGB 1998 for output, especially if you are printing, either for pleasure or output.

If you use sRGB, the colours are different, mainly used for screen output, and not nearly as pleasant.

There's something to be said for retaining sRGB for posting to your phone or on an iPad whilst employing another color space for your printing

 

Those DNG files are big and I didn't know about the lossy thing so thanks for that

 

Of the 20-odd RAW captures I've developed (using CS3) these have taken the absolute least amount of tweaking I've ever done: just whip some serious USM on there and presto/chango they look terrific
