    noise on photos

    Hi is there anyone that could tell me what im doing wrong, im trying to learn how to use my canon eos 7d im using a 17-55 lens ive been taking photos using av and tv settings the photos look lovely on the viewfinder but when i load them to the computer and zoom in a bit they are covered in noise on the skin, ive got the iso set on auto to a maximum of 1600, any advice would be greatly appreciated
    thank you

    Probably too liitle light or too high an ISO - the 7D is known to be unforgiving in these situations (and I use a 7D too!)

    Can you post some sample images with the EXIF data?

    Cheers,
    John

      ISO1600 on the 7D is quite noisy, however, what will make noise even more of a nightmare is under exposure. Especially in out of focus areas, and if your subject isn't well lit the noise will just be something you'll have to deal with later.

      Trying to keep the ISO as low as possible has a lot of advantages too, like colour reproduction and contrast, however, the higher you go no matter the camera the more likely it's going to creep in. Well exposed and good focus subjects tend to have less noise. Zooming in on a picture will tear you apart also.

      I don't know what type of software you are using for processing the images, however, if you are shooting in RAW noise can be taken away no bother. If it's jpg then there is still a mild amount you can clean up. I'd advise shooting RAW and processing in Canons DPP or Lighroom for noise control. Very easy to do. If the 17-55 is the canon 2.8 lens then remember you can get away with shooting at lower shutter speeds for still subjects, and lower the ISO.

      Post a wee pic in the replies so we can see what you mean too, that can help :)

        +1 on using low ISO on the 7D. For portraits, ISO 100 is it. Period. Adjust the light, not the ISO. If you are shooting JPEGs, switch to RAW and use Adobe Camera RAW in Photoshop or Lightroom and try the noise reduction settings there. Canon's DPP has noise reduction, too, but I've not been impressed with the results, and the interface is a little clunky. If you can find an old Noise Ninja, that is the best as far as I'm concerned. The publisher, Picturecode.com, has recently dropped that product and incorporated it into a more feature-rich, more expensive offering, which I've not tried.

        Best bet is to not have to reduce the noise, though, and low ISO plus good exposure are your best bets there.

          I try to not to go over iso 800 on my 7d ... noise is definitely a bit of an issue with it... imho.

            I have the 7D which my wife mostly uses, and a SL1/100D, the Baby Rebel, with a similar 18mp sensor and Digic 5 processor. Noise can be a problem, but as a friend pointed out, if you have to choose between noise or motion blur from a slow shutter speed, what do you prefer?

              I normally set my ISO on Auto and set the Auto-ISO limit to, depending on the situation and subject matter, between 400 and 1600. Using aperture priority, it seems like the camera tries to achieve a shutter speed no lower than 1/focal length, without regard to stabilization. As a result, it does seem to dial up the ISO a little sooner than I would manually. Shooting mainly handheld, this works out OK generally, although noise reduction in Adobe RAW can sometimes hurt fine detail, so some noise makes it to the final picture. I think printer bleed helps reduce noise also.

                It is but... With the right shot, I think you can get away with something over 800. For example, shot at Chester Zoo with a 7D and 70-200 + 1.4x tc:

                OK, so it's got so many other flaws in the shot I can't count them but at ISO 12800 it has no shake and it's in focus

                  Haven't tried it myself yet, but I have old bodies and ISO 1600 (!) is a little noisy. I run DxO Optics Pro 9, and the PRIME algorithm is meant to be the DB's at dealing with noise.
                  Anyone else had any experience with this? Would it be any good for the 7D?

                    I always used to run a surface blur on the background in photoshop and then mask the subject out. noise gone :)
