Different photos from LCD to uploaded ones

[portrait from photo]

Hello everyone!

I feel really frustrated nowadays because I thought the pictures that I see through my camera LCD are the very same ones that I will see upon uploading and/or printing them. But I ended up having grainy pictures What must I do?

Never trust your LCD screen. I have had photos that look great on the LCD screen, but look like crap on the computer. On the other hand, I have had photos that looked like crap on the LCD screen, and looked great on the computer.

What camera are you using? The key to getting less grain (digital noise) is to use the lowest ISO, and get the exposure correct. Noise really shows up when you underexpose. Can you post an example, along with the settings used?
