Fuzziness??

patrick0294 · Jan 31, 2012

I always thought it was my camera's ISO setting on above 400 at work. However, I took this on a tripod at 3 second exposure, f 2.5, and ISO at 100. What could it possibly be? I also used a tamoron 17-50mm f2.5 lens.
Im talking about the fuzz on the ear cups of the headphones, background etc.

Was this jpg or raw? What compression setting was used for the jpg (either in camera or post)?

patrick0294 · Jan 31, 2012

Jpeg, 15mp 4752x3168, as far as the compression I am not sure. It is straight from the dslr btw (Canon Rebel T1i).

On the foam ear cup? That's blur from shallow depth of field.

Google for a DoF calculator to learn about how narrow your area of focus will be at any given aperture at any given distance.

I dont think thats the problem. Here is a bigger DOF, look around the B http://i.imgur.com/hAMKR.jpg

Its supposed to be a flat white color.

it seems like you have WB problems AND depth of field problems...

Thats not what I ment, The white is supposed to be the same color on the whole ear cup. See how there are different shades covered in fuzz?

And unreasonable expectation problems related to under exposure and image noise?

photog4life · Jan 31, 2012

and exposure problems... brighten it up with a deeper DoF and it will be pristine...

At f9.0 and I lowered the shutter speed, turned on the lights. Still got the fuzz. I have no idea what it is.. http://i.imgur.com/ZIOgl.jpg

it's long exposure noise

noise isn't only caused by high iso

it will go away with a faster shutter speed

Looks sharp to me (where it's supposed to be sharp anyway)

Maybe its my monitor. Try moving a little closer to your screen.

it helped alot though... no matter what there will be some noise... i zoomed in and i couldn't see much noise... but 2 second is a long ass shutter speed...
