Camera Quality and Noise

Often times on the message boards someone will ask the question 'Is my camera up to the task of capturing quality stock images?'. One of the many things to consider when buying any sort of camera equipment for use in shooting images for resale is, of course how the camera itself handles the issue of noise. Many think that purchasing a small fixed lens consumer point and shoot with 7 or more Mega-pixels of resolution ,rather than a digital SLR, is sufficient to produce quality images. But the number of megapixels is just one facet of a much larger issue when it comes to successfully avoiding noise; and in the case of smaller sensor sizes, can in fact end up contributing to the generation of more noise.

The following web article on noise discusses in very simple and clear terms what noise is, how it is generated and how your equipment quality and sensor size (as well as individual photo sensor size) is important in avoiding noise during initial capture.

I'm shooting with a Nikon D70 at ISO 200 and I rarely have noise issues. I notice that some of your images are with a fairly dark background. Maybe try with a white background.

I have had been rejected some photos, for noise on the images, I'm using a 24 Megapixels camera, even at ISO 100 images has noise on a sunny day when zooming to 100 %, as biger the image as more details it captures, it is like looking at the big street sign at closer distance, if you apply a noise reduction filter, all de details of the adge go away and this guy considerer it as out of focus image, Who understand this people? I got a message that say I need to look mi images at 100% before to send it, I do it, I have a 30 inches screen to no detail be ommited. So, we keep the natural noise of the image and be rejected for it, or apply a noise reduction filter and be rejected for blurred photo?

Yes, thank you for posting the link. Although I am always trying to shoot to avoid noise, it is nice to have more technical information explaining noise.

I think you get to know your own camera over time. A correctly exposed image seldom produces much noise, Ive had images taken in ISO 800 that have been accepted and even sold as an EL once or twice. If Im using a high ISO because of the situation that cant be helped, I generally overexpose the image by a half to one stop to reduce noise. My LCD is also set to bright on the camera so that if Im in a situation outside where I cannot see it properly, it wont be underexposed. this is crucial to me as I shoot everything in Manual mode :D
