Iso noise test

[Cutter]

The two pictures below are with an iso setting of 3200 and 1000 on my canon 50d.
I have asked Garry (cathus) if he would post two similar photos with the same iso on his 1d mk3 so I can judge how much noise difference there is. It may be of interest to others to see if or how much difference there is, The 50d is not good over 400 in my opinion.

Both photos were taken of a plain cream wall then cropped to 100% actual pixels with nothing done just exported from bridge. Not sure if you need the exact camera setting to compare

Iso 3200 Canon 50D


Iso 1000 canon 50D


They both look bad to me ;(

Are these jpegs with NR applied or conversions from raw with no NR?
Have they been sharpened? If so by how much?

I think you need to give some more settings, like what colour cream was it exactly?

Cheers, Sie

They were raw concerted to jpeg, just default settings from bridge. Hope that is enough info

By the way, these are cropped (so no re-sizing) RAW files, and saved as JPG quality 10. Nothing else.

Hope it helps.

Hi Mark,


I agree, the noise looks quite bad. I just took two shots of a plain wall with the D90 and compared the 4 shots side by side. Your 1000 iso looks worse than my 3200 iso


ISO 3200





ISO 1000

Interesting subject but you can't compare shots with different cameras at different locations. Cutters light may be different from Matt's. I've taken shots with the D3 at ISO 6,400 and while one looks great the other has noise, and in these cases the speed was the same but the Apteture was different. To do a real comparison the Shutter speed and Aperture must be the same, as well as the light.

A fair point, the amount of light will of course affect the noise that's visible. There's always this for a comparison of sorts...

As Oldboy says you just cannot compare such shots unless in the same setting / lighting conditions. You have to either trust other party reviews done in those conditions or find a mate locally wit other gear and se up the tests yourselves. The subject is key too in terms of how much shadow there is to exhibit the noise.

Thanks guys I thought it would not be easy to compare
