Getting grainy results....

[NDA]

For some reason, RAW images from my new Fuji X20 are very grainy. Exif data shows typical IOSO of 400 (the camera is set to automatic).... Jpegs are crystal clear.

Am I doing something wrong?

What are they like @ 100 ISO NDA ?

If they are better, than the camera isnt very good at hIgher ISO.

Also, if you process the RAW to a good JPEG is the result any better ?

Remember your jpg will be automatically sharpened and boosted in camera.
RAW requires you to do that yourself but with a greater degree of control.

Also some people will tell you to move off the auto settings.

They're fine at 100,really nice....

I have processed to DNG - would I get a better result processing to jpeg (I know my way around, but am not an expert)?

I've tried to sharpen and reduce noise etc, in DNG but haven't had great results.

Is there a danger of fixing the IOSO at 100, rather than 'auto'.

Many thanks for the responses. Appreciated.

Mmm,it does sound like its not great at higher iso.

If you have a decent processing software, have you tried noise removal first ?

I haven't..... The Fuji has RAF files and their native program is called 'Slinkypix' or something similar.... I need to have a play with that as its all very new to me. I've used PSE8 for a long while, so the Fuji stuff is a bit of a mystery!

This is the downside of goimg 'off piste'...

Yes, maybe.

I always shoot RAW with my Leica... Hmmm. Maybe I'll stick to jpegs with the Fuji, or play around with the settings a bit more. It's a nice little camera and I'm enjoying the immediacy of autofocus!

That's one of the downsides of a 2/3" sensor.

Quite a significant size difference between 1.33x and 3.93x crop-factor sensors...

The Fuji an unusual colour filter on it's sensor which is only recently supported by Adobe. I imagine this may be causing problems for the noise reduction algorithms. Try processing a couple with the Fuji software and see if the issue still applies.

The danger would be that your shutter wouldn't be quick enough in low light situations, so your shots could be blurry like this one (unless you use a tripod or have a very steady hand!);



But if the jpgs are coming out fine at ISO400, it must a processing software issue, not a feature of the sensor or the RAW files....I think...

[upsidedownmark]

My thinking is that the odds are on processing from sensor->jpg is performing a whole bunch of noise reduction that isn't there in the raw file. You should be able to duplicate that in CS/Lightroom/whatever.

Try other software.

The developers are still getting to grips with these Fuji sensors - and as ever the manufacturer keeps changing thinks as new models are introduced it seems.

We all need standards - as many as possible.
