    Went shooting this afternoon with l33tpilot at the Air & Space Museum. Long story short a lot of my images had substantial noise. Had a few questions for 50d and 40d owners shooting in the 800-1600 iso range. I was playing around with ISO settings and testing quality.


    1. I read that the "noise reduction" setting only applies to shooting in JPEG and NOT in RAW. If you shoot in raw do you run your images through a program like noise ninja if you shoot at a high iso?

    2. Used a kit lens 28-135 IS in this shoot and was wondering if better glass actually helps reduce noise problems. Aside from the aperture will a better quality lens show less noise at the same iso level?

    3. From my images it seems like I'm stuck with iso 800 and below. Does this seem normal to you guys? Maybe my expectations for the 50d are to high.

    Yes. I usually use Noiseware though.

    Faster glass will allow you to shoot at slower ISO's, so yes, it will help reduce the noise problem. But better glass at the same ISO will not effect the noise (caused by the sensor).

    Not a Canon guy so I can't answer this, but don't be too discouraged about noise. Print a "noisy" picture to see how much of that noise actually transfers to print...you might be surprised.

    Sweet thanks for the responses and will look into noiseware.

    Noise Ninja is just as good (debate on whose better), I just prefer Noiseware.

    Would figure from the reviews I've read (before I purchased) that it would at least be great up to 1600. :dunno:

    yeah, you don't really want to go above 800 on the 50d but that is being rather nit-picky. at 1600iso it's not completely unusable from the 50d, but don't even look at the "expanded ISOs," they exist for marketing, not for use. the 40d has much better ISO performance though. i do some noise reduction through ACR, but have been looking at acquiring noise ninja in case i go a little too high.

    I remember seeing shots as high as 3200 or 6400 ISO and they were completely usable. :dunno:

    Yeah I will post up a few 1600 iso shots and see what you guys think. Maybe I'm being a bit picky.

    Just pulled off the camera and resized. Didn't do a damn thing otherwise.

    40d, iso 1600

    The shots aren't anything special but it goes to show that if you get your exposure correct to begin with you can get some clean shots at higher ISO's. If in doubt expose to the right and bring it back down in post, exposing to the left and pushing just makes more noise.
     
  14. 1. I use Lightroom, and adjust the color to mask the noise on my Rebel XT.

    2. The IS doesn't really help when doing a longer exposure, so if you shoot ISO 100 and your exposure is 0"6, you might have some blur. But it depends on your F stop, I think the 28-135 is a 3.5-5.6, anything lower like a 2.8, 2.0, 1.8, 1.4 or 1.2 will allow you to shoot lower light much better (without having to use a higher ISO)

    3. The 50D has it's pro's and con's, the 12,800 ISO is just god awful, I can't imagine ever using it. ISO 3200 and 6400 are quite nice, but I think 3200 is a stopping point for me. The 50D's 12,800 ISO will most likely be fixed with the 60D.

    programs like noiseware huh? are they better than using high iso NR on the d90?

    He means pixel peeping is a practice you should give up and start realizing noise isn't a huge issue unless it detracts from the photo.

    Also that it's mostly unnoticeable unless you peep.

    I assume pixel peeping is blowing up the original image and zooming into the picture closer?

    Example of 1600 iso I shot with the kit lens. It's probably just my horrible exposure skills. What do you think? Is it just me?

    Actually, what I meant was that most people who complain about noisy shots don't usually understand exposure for shit. They'll constantly trust their meter and underexpose shots in the shadows then blame the camera when noise shows up after pushing the image a stop or more. Or, some people will have their LCD brightness all the way up, never look at the histogram and then, again, introduce noise in post. There are all kinds of ways to introduce noise that can be avoided. Sure older cameras can get noisy and most of the time it really does not matter, especially if you're printing them.
