Photography Question

resolution


I work for our church and have 2 cameras; a Nikon D80 and a Panasonic Lumix DMC-FZ20. When I take photos with the Nikon and submit them to be printed by our printing company, say for the local newspaper or our church newsletter, the photos turn out grainy, but when I take with the panasonic, they seem to turn out better. Both cameras are set to their highest resolution. Why is this?

Hi Tara,

'grain' is a term from the chemical film days. It's digital equivalent is 'noise'.

Noise is generally the downside of a high(er) ISO. So I would check both camera's ISO settings.
To get less noise on the D80's images set a lower ISO.

However, a D80 and an FZ20 have different size sensors. Which is why the same ISO setting may get different noise levels on either camera.

Have fun!

  Tara,

It is obviously something you have not set properly, like ISO as W.S suggests.
The D-80 is far superior to the Panasonic DMC-FZ20 in build and image quality.

Tara R. Swartzendruber   Actually I generally have my ISO set to 400 or maybe 800 for indoor shots and 100-200 for outdoor, so I don't really think it's that.
It's a local print shop. Is there any way that the print quality of the photo exceeds their printing capability? Strange question, but I'm just wondering. If I print the photos they look great, but in publications, they don't.

  What files are you actually submitting (what is the format)? Are you submitting raw files, and the printer is only able to utilize the much smaller JPEG preview? Or, TIFFs and the printer can only work with JPEGs? Or, vice-versa?

I'd bet that your Lumix is producing JPEGs by default. Is your D80 producing JPEGs by default as well?

"I generally have my ISO set to 400 or maybe 800 for indoor"

Those are relatively high ISO settings, Tara. The D80 has known noise issues at those levels. Against that background your experience is not surprising.
But, anyway, if your print of a particular file is good, and theirs isn't, then obviously there's something not kosher at their end.
The proof of the pudding is in the eating: test it! Have a dozen diverse pictures printed at your usual print shop AND at another print shop. Then observe the resulting prints side-by-side.

Have fun!
