I shot with ISO 1600 to help blow out the background.

Should I lower the ISO and up the exposure time? They look grainy and the case is black so this is not portraying exactly how the case looks ...


Thanks ahead of time for the help ...

ISO 1600. Answered your own question.

The graininess is digital noise. The higher the ISO, the more noise.

Yeah try again with ISO 100 or 200 and a long exposure if you have no flash.

Lower the ISO or reduce the noise with software. I use higher ISO all the time and Topaz DeNoise is an excellent program for reducing it. Also, a lot of people will over expose just a tad when using higher ISO. Then, pull it back in PP. An over exposed image, even at very high ISO, will show a lot less noise than one that is underexposed. If you are shooting RAW, you can always pull back from being a full stop over exposed, but all you really need is about 1/3 or 2/3 overexposed. Play around with it until you figure out what works best for you. I have view many images shot at 3200 ISO on cameras that people complain about the noise on. It is all in the exposure. If you expose it right, you can reduce the noise.

Sorry, I should of elaborated more, but others have given you the same advice I would of.

On a side note, I would rethink your composition. The front of the case is very dark, and the reflection off the side of the case is distracting. Can you shoot with the light source at the front?

Are you shooting these handheld? The first two look like they have signs of camera shake.

What shutter speed? Using a timer or remote shutter release?

Light source is a big window behind the sheets ...

I agree with others on the soft images, but with the set up you're using there certainly shouldn't be any camera shake (??). Hmm! Funny focus point perhaps?
