Grainy Photos

David Mancini , May 26, 2008; 09:30 a.m.

I bought a new D80 and am not happy with the quality of the photos, I have had a d70 for years and the quality is far superior to the d80. my d70 took crisp, clear photos, I have been using the D80 for about a month indoors and out and the photos are grainy. I am not very pleased so far. I bought the new camera so my d70 would be a backup but I guess it's the other way around. This is from my d80 http://davidmanciniphotography.smugmug.com/gallery/4390314_wuZPt#301567501 _pa8rK

Please any advice. Thanks David

Are you using automated settings? Is the ISO at base or on auto? can't tell from the samples you posted.

Too many "unknown" issues to make a reason why call.

You could supply the settings you used for the D80 image. Did you use the same lens on both images? The same lighting set-up? The same ISO in both camera bodies? Are you only comparing images on your computer screen, or did you make an 8x10 print of each image and then do the comparing?

Grainy is good for some images, and like what makes a good image is subjective to each individual viewing tthat image.

Data provided by the "info" flag for the first photo says it was shot at ISO 2000. I'd say that's the problem. No data is provided for the older one.

David when I used a D200 (same sensor as the D80 if I remember right) as a follow up model to my D70 I found at 100% viewing a little more noise at low ISO say 200 from the D200 as compared to the D70. I needed to sharpen a little more careful in cases where strong sharpening was required. For best results I often needed to slightly filter noise using "neat image" in comparable situations where I did not needed this with the D70. This irritating noise was discussed a lot a the only drawback when the D200 came out. Over all the D200 is a nicer camera than the D70 however at small image sizes and when the viewfinder is not important the D70 is a very nice camera.

Are you talking about these slight differences?

The first time I shoot with my D300 I came running to the forum asking the same thing. I thought it was noise. I was told to print them. I made prints size A4 and there was no even 1 tiny bit of grain. Those pictures I saw in your folder look the same as what I thought was too much noise. Also on my D80 I always try to shoot at ISO 100. I think ISO 2000 would be too high. Good luck! Rene'

David, Two things:

As mentioned, your shooting at ISO2000. That is going to be SUPER noisy 'grainy' on just about any DSLR.

Also, your using f/18.0. That's too small for getting the sharpest results from a DSLR. I find that past f/11 the images start getting softer. You'll have more DOF, but detraction starts to soften the whole image.

I'm not sure why you're using ISO2000, but turn it down to ISO100 (the lowest setting), open up your aperture, and turn up your lights to compensate.

Espen Stranger Seland , May 26, 2008; 10:58 a.m.

Comparing noise between D70 and D80 at 100% magnification will give you more noise on D80 because of the higher megapixels.

Compare the noise with equal sized prints.

Alan Olander , May 26, 2008; 11:21 a.m.

I am wondering why you would be shooting at ISO 2000? There's your problem.

Elliot Bernstein , May 26, 2008; 11:51 a.m.

Your D80 will give you low noise images up to about ISO 400. Above ISO 400, you will need a good noise reduction program.
