n00b Question.

[RKRAMOS]

Hello everyone, I was taking pictures a couple days ago and noticed that, after I put my pictures on the computer they get a "gritty" look, I'm not sure how to explain it but it looks like there's a bunch of specs in the pictures. I'm not sure if you guys understand what I'm talking about . I'm not sure what could cause this to happen? I hope you guys could give me some answers so I don't have this happen again

I'm uploading a picture now to show you guys.

If you are referring to grain, then your ISO is most likely too high. Either that, or you have a dirty sensor. What camera do you shoot?

I have a Nikon D5100. You say the too high of an ISO, I thought the higher ISO the more clear the picture comes out?

Your ISO is 6400... that's pretty high.

Do you really need 1/800 sec @ f/11?

I guess not, I was just trying to compensate for the lighting. What would be a good rule of thumb for controlling ISO?

ISO is the equivalent of film speed, so for digital cameras it is how sensitive your sensor is. Higher ISO will allow for faster shutter speeds in lower light, but it will cause grain in pictures.

This.

Shoot 100 or 200 unless you absolutely can't get a shot w/o a faster shutter, then go from there. The higher you go from there, the more quality is reduced.

Start out with ISO 100. If you can't get the shutter/aperture combo you need, ramp the ISO up until you do.

So for brighter pictures use a higher ISO and as the light gets more dim go lower with the ISO?

Backwards. In lower light, up the ISO. In normal/sufficient light, I wouldn't exceed 200 ISO.

I'll definitely try this next time. I always assumed the higher the ISO the more clarity the photo will appear.

Oh, wow, no wonder a lot of my photos from that night came out grainy. Thanks for the info. I'm definitely going to remember this next time.

Low ISO = best quality pictures
High ISO = cause grain and 'spots' in your photos

Always try to shoot at low ISO's but if you're shutter speed becomes too slow to use then increase the ISO
