40D High ISO Noise Example (With Crops)

I have been reading these forums for a while, and I have noticed alot of 40D noise examples around purporting to be in "low light" at High ISO.

Unfortunately I don't believe you are testing the noise ability (or inability) of a cameras sensor if you are shooting faster than 1/100 s. So here are a couple of examples. All of these were processed with Lightroom, and nothing more.

The following two examples were shot with the Canon 50mm 1.4, beware it goes down for a bit.

1/100 s 1.4 ISO 1600

it is a shame you did not shoot the same subject at different shutter speeds to prove the point you are trying to make.

But I agree if you get the settings right on the 40D i think the noise is slightly better than 30D, but if you get it slightly wrong it is worse than the 30D slightly wrong.

I guess I wasn't trying to prove the point that higher shutter speeds give more noise. I was under the impression that it was common knowledge.

But that is a good idea! I'll do it sometime shortly.

Thanks for this, Agent.

Prof, a higher shutter speed simply means (all other things being equal) that there's more light available to the camera - a sub 1/100 shutter speed implies proper low light shooting.

Indeed it does - an ISO3200 shot with a shutter speed of 1/1000s make me ask why you'd use 3200 in that situation? More light being available means choosing a more appropriate ISO setting. It also means less shadows are likely and that's where you're more likely to see real noise.

I saw a D3 shot taken at ISO6400 with a shutter speed of 1/2500s - it proves little.

agent.media,
You didn't look to hard then.
I had posted a test comparing the 40D to the 5D with long exposures from 1 second all the way to 1/8000th a second, high ISO 1600 with large aperture test here
However I do agree with you, as I love my 40D too

To me it looks like you still had the Lightroom noise reduction turned on, the distinctive grain kinda gives it away.

You might be right, As I never checked it.

And to boot, I had the internal camera noise reduction on.

That noise appears manageable.

A quick run through Noisware and it will be very manageable...

As a related comment.....
Create a preset in Lightroom with no sharpening or noise reduction and make that the default preset on Import. Then you don't have to think about those parameters and you always start from 0.

Awesome suggestion! Thanks!

So then what would the sports shooter do? I routinely shoot at very high ISO and shutter speeds much higher than 1/100 to stop action. It seems to me that you pick the aperture and shutter speed you need for the effect you want, and then the availability of clean higher ISOs allows you to not have to make as many sacrifices.

Agree, since I found Noisware - I'm back in love again with my 20D...
And 40D frames after Noisware - couldn't be better!

Looks like it to me too. If you've never played with the default settings, LR should be set to Luminance 0/Color 25 (I think).

Are you all saying that higher shutter speed produces more noise?
