Hi I was trying to take landscapes in cloudy conditions and the results were not very impressive. there was a lot of noise in the images. I used a Canon 7D with a canon 50mm f/1.8 lens to get the shot.
Hi Manvir,
Canon seems to be proud of the well packed new 7D. A lot of pixels on a small helicopter landing pad for photons! This means it will resolve the diffraction artifacts caused by time apertures less than about f8 or f11. However that will not cause noise. However if you do use a tiny aperture to get increase depth of field for landscapes, then you do risk cutting down the light so much that shadows are noisy. The way around that is to use a tripod. however, if the wind is moving branches, then that can introduce blur. You can go around that be increasing speed and ISO but then the noise increases. So everything has consequences.
So what to do?
Well do the best you can. That means use the lowest ISO setting in which you can use an f stop of say 5.6 wherein your DOF is reasonable and your shutter speed is fast enough for your needs. In reality, noise is unlikely to be the thing that ruins your picture. more important is the choice of scene and the time of day.
Show us the picture and we can try to give feedback that will be helpful to you.
Don't worry about a picture being technically perfect, just be concerned with seeing with your mind what the image might look like on paper. Hardly ever does a picture get spoiled after that.
