My Raw image looks grainy!?

I'm still new to the world of pro photography.

I'm working on Raw in Lightroom and PS cs3.

The photos I shot in Jpeg and Raw and noticed the Raw is more grainy then the

jpeg's.

Those sharpening fix that? Gisela

A raw file is the beginning of all. You decide if you let the camera do a certain amount of processing (by selecting jpgs straight from the camera) or if you want to do all the processing (by selecting raw).

 

If you decide for raw, the burdon of doing the right things is on your shoulders. It's a fact, that digital signals as they come from the image sensor contain a certain amount of 'noise'. The amount of noise is depending on quite a few things. If you decide that the camera shall produce jpgs, the camera will apply a noise reduction filter on the raw data. If you take the raw data yourself, obviously no such filter is applied. This is in fact a good thing, because you can decide how much reduction of noise you find necessary.

 

As said, raw gives you more freedom of choice when editing, but also asks for a few more steps in postprocessing.

 

Oh, BTW ... no, sharpening will increase noise ... reduce noise with a noise filter before sharpening.

Check the exposures to see if they are the same. Grainy is usually a sign of underexposure unless you're shooting at a high iso.

Posted examples would be nice.

 

Perhaps there is some default sharpening taking place in Lightroom. If oversharpened

they can look"crunchy."

 

Knowing something about the ISO setting would also help with the diagnosis, but a visual

and metadata would really help.

 

Are you talking the same pic in jpeg and raw at the same time and the raw is grainy?

A lot depends on the specific raw converter you're using, as well as its settings. Typically, the raw converters supplied by the camera manufacturers process your raw files to images that look a lot like the camera's jpegs, partly because they can, e.g., read your camera's noise reduction settings embedded in the raw file. Images processed in 3rd party converters that ignore most of these embedded settings (including Lightroom and CS3's ACR) can start off looking quite different to the jpegs (which may be good or bad!), but any decent converter will have many adjustments (including noise reduction).

BTW, sharpening will accentuate noise.

Thanx,i think noise reduction is the answer!?Here a the pix.

Both at f/2.8 ISO 800 I/250S.

Hope this works! First time.

First one is Raw.Second jpeg

Here the jpeg.

They are way to big,SORRY.

I also have them in my folder under sample.1st jpeg. 2nd raw.

Gisela,

according to exif data, the images are taken with ...

 

1/250sec f/2.8 800iso 50mm flash-fired

 

... it's the 800iso that is introducing noise ... and in the scene captured, its not required to use 800iso at all. 400iso and 1/125sec

had worked as well, and had resulted in visibly less noise.

 

Nevertheless ... using raw, it's you who's in control of the amount of noise reduction to be applied.

Thanks for your time.I read about noise reduction in my books but wasn't sure if that was what i need to apply. Still learning:-)

The first one looks much better to me less colored noise in the hair. Remember also that viewing at 100% is like looking at a huge print.
