After my disappointment at the way I failed to capture what I wanted for the "Team Sports" challenge with the Fuji. I took the chance to try again under the same conditions but this time with the 20D and the 70-200L F4 lens.
These shots are with the camera hand held at ISO 1600 which allowed me so much more scope than last time.Some shots did have a bit of motion blurring, but under the conditions, I was delighted with the results and provided you don`t oversharpen then there is little evidence of noise in the images.
I even managed to get one of the images used for the official website report on the game..if you`re interested click here
Roll on the next "Team sports" challenge.

At that ISO 1600, they are amazingly clear!!

Far better than I was expecting Terry,bearing in mind that the camera wasn`t on a tripod..makes me wonder what sort of shots I would get on a nice sunny day with the scope to be able to raise the shutter speed.

Ironically, I`ve had much less time for photography since getting the new kit Paul...mainly because I`ve had to be a good boy and get all my long overdue chores done as a payback for the pressie. :)

Tony, I`ll keep a look out for that..thanks.

I am Sooo jealous.
I'll have to wait a while before I can get one of those babies. Maybe the Rebel replacement might be worth waiting for.
Great shots!

Some great stuff there.

That is fantastic at ISO 1600.... I want one!!!!!!

10/20/2004 09:14:04 AM · #10
Thanks for the shots, Graham. Now I want a 20D even more than I already did!

I`m delighted with the quality rather than the technical aspects of the shots Bob. As my purpose last night was to test the equipment and little more, but there`s no doubt an ordinary image is improved immensely with this kit.

can you post a link to one of them full size (or close?) - feel free to put a watermark on top of it. i would just like to see what noise does come up on the full size as resizing down often hides a lot of flaws.

thanks for your time and nice shots!

I don`t have a website that I could link you to but I`m willing to send you a full size version via mail if you are able to handle that?

Gordon, maybe just chop out 640px by 640px from the original?

Will do..watch this space..............

Here`s a 640x640 of the original...had to get rid of some of my portfolio images to make room for it as I`m just about at the limit.
' . substr('//images.dpchallenge.com/images_portfolio/14603/thumb/114300.jpg', strrpos('//images.dpchallenge.com/images_portfolio/14603/thumb/114300.jpg', '/') + 1) . '' . substr('//images.dpchallenge.com/images_portfolio/14603/thumb/114301.jpg', strrpos('//images.dpchallenge.com/images_portfolio/14603/thumb/114301.jpg', '/') + 1) . '
I`ve added another 640x640 section from the other image which doesn`t suffer so much from camera shake and gives you a truer reflction of the noise.

Images now removed to make space on my portfolio

If you e-mail the full size ones to me, I can put them up on my //www.brownt.co.uk site??

Thanks for the offer Terry, I`ve posted a 640x640 section but would be happy to take you up on the offer should anybody want that.

Does the L glass have anything to do with reduced grain?

That`s a good question..not being an expert on this, I wouldn`t like to hazard a guess on on how much(if any)effect the quality of the lens has on reducing the noise in the image.
Perhaps someone better qualified to answer this might be able to explain ?
10/20/2004 01:46:07 PM · #21
Here's my estimation on lens affecting noise:

All the lens does is directs light onto the sensor. On a cheap lens this is done badly, on an expensive lens this is done well (with relation to sharpness and distortion). However the light is directed it still hits the sensor in an essentially uniform manner. Hence, L glass does not reduce noise.

Edit: Corrected typo.

No

surely you used something to clean up the noise...like neat image or noise ninja...right?

Not a thing...the 640x640 crops are from the original image.
The processed images were adjusted for contrast and sharpened but nothing else
