Guidance On A Grain Rejection Please

Sun Aug 20, 2006 6:51 pm

I've had the photo below rejected for 'Grainy'. Disappointing as that is I want to learn where I have gone wrong and put it right.

I'd welcome views on where the grain is and if someone could explain the difference between grain and noise, or are they one and the same thing?

I've had a look again at the image and thought the grain may be in both the engines and on the tyres? The picture was taken in superb light, early morning (0950), with a 30D and an L series lens at 100 ISO.

I loaded it at 1600 as it almost required no crop and it looked as though the quality was there (got that wrong then).

I have taken the attitude on this site to take these rejections constructively and learn. I'm no expert but it seems that if you reveal too much detail in the shadow areas noise appears - perhaps someone would be kind enough to confirm that. To reduce the appearence of the grain is it better to darken the areas with say a levels mask, or use the noise reduction filter?

Thanks

Hi Garry

Seems to be only in the shadows so might be something you did in PS. Did you try any shadow/highlight or other tricks as this is known to give a griany look to shadows?

Hi Tony - yes I would have lightened the shadows a touch in PS. Perhaps I've just overdone it? Do you think its salvagable and worth another go.

Thanks

It will be fine just keep the shadows as shadows!! As the old advert goes "I think we over done it with the sherry"! Seeing this a lot now and easy for the screeners to spot.

Bye

I agree, keep the shadows as shadows. I see a little grain on the underside of the belly. Maybe it's just me, but I see far more jagged edges than I do grain. The titles/reg on nose wheel/right wing leading edge/stripe towards top of the fuselage. Nobody else seems to have mentioned this, so is it just my screen? You could try to reduce the size. I have been advised to do that on the odd occasion in the past. Good luck with a re-upload.
