Hi all.
I am relatively new to this forum and am posting for the first time. I just recently got a Cannon Rebel XT about a month ago and I am still learning how to use it to it's fullest. Last weekend I took some shots of the golden gate bridge and I am pretty disappointed with the results. All of the shots came out very grainy. The sky wasn't a sharp solid blue. The whole picture looked very grainy if I zoom in even a little. I shot the pitures on the 'P' setting which, as I understand, automatically sets the shutter and aperature. It was extremely sunny and bright. Other pictures I have taken have not had this problem. Does anyone have any ideas why this could have happened?
edit: now that i think about it, i may have had the ISO setting a little high. maybe that is what caused the problem. |

| that could have been the issue i have the 350 rebel xt and im repeatedly disappointed in the shots i get at any ISO over 400. I do almost everything at 100. |

| I have a Kodak and mine did the same thing--bright light, ISO 400, very grainy. |

What?
The XT is known as one of the best cameras to use at high ISO. If you are at a high ISO use a wider aperature and the grain won't be a problem. Check my profile, all of the music shots are at ISO 1600. If it really bothers you, you can always get Neat Image or Noise Ninja. |

I agree.... I love the quality of my shots, 1600iso looks better then most other cameras at 800iso....but that is my opinion

Ok, let's get into this right...
Could you please post the photos and the basic shooting stats like shutter speed, aperture, ISO, and the lens you were using with a rough guess at focal length...
There are so many variables here...
I took some 30 second shots the other night with my 30D at ISO 400 and I got some grain too... there are quite a few variables here...
give us a look at what you are looking at and we will give you some more concrete answers...
PS. I do agree with what has been said up until this point... Canon CMOS sensors are top of the heap for noise...
No offense to kat75, but there's rather a huge difference between noise characteristics between a P&S and a Rebel XT.
I'm quite surprised that you are experiencing noise issues as low as ISO 400 jaded youth...
Might be caviar tastes too...
I have a Neat Image plugin running on my Photoshop and it doesn't need to do a whole lot in most images... I used very minimal NI on my 30 sec images and cleaned them up lickity split... The noise profile of the 350XT isn't tooo far off that of the 30D.
Oh yeah, make sure you are using NI as a FIRST step... it's been discussed elsewhere in the forums, but you will find that it makes a BIG difference.

What lens are you using?
Buy a circular polarizer and shoot on ISO200.
Overcast days are better.
Learn to shoot with either the Tv or Av settings before moving on to the M (manual) setting. In the meantime, use the auto setting if that helps and then look at the data from the photos afterwards and write down the data of the best shots. Then go out and see if you can recreate using the M setting.
Read up about the Stop-Down button and check that before shooting.
