Hi guys

Just wondered if any of you struggle with the noise levels on this camera. I wouldn't risk using it for something important over ISO 800, for examples :thumbsdown:

Kind regards

All advice gratefully received

Well this one was at ISO 1000 and I have no problem with noise One point have you Turned OFF teh two setting on teh 50D high iso speed noise reduct'n and auto light optimizer i al turn off long exp noise reduction

Sorry, didn't get that; what do I turn off and how do I do it?

Thanks
 
I regularly work with my 50D at ISO 1600 all the way up to 3200. May look less than perfect when pixel peeing at 100% but reduced to 7x5 prints are perfectly OK and they respond to noise reduction during PP.

Maybe thats my problem then - I do tend to zoom in and judge it. :bang:
 
Guys, I couldn't understand Chaz's earlier recommendation. How do I achieve what I think he's suggesting?

Thanks again.
 
They are in the menu on the second from last tab. Scroll across to find high iso and illumination and disabled both. Hope this makes sense

Thanks. A combination of your's and Chaz's directions got me there in the end! I'd be interested to see what difference this makes.

How come turning OFF the noise reduction settings actually reduces the noise??? Or are these particular custom functions about as useful as an in-camera red-eye removal tool (and we all know how efficient they can be)? ;)
 
Still don't get the point of shooting in high ISO and then looking at the image at 100%- its never going to be perfect.

Last year at ‘Focus on Imaging’ Canon guy doing the 50D talk told us about it.

Not exactly struggle Sarah, but yeh if you are on a high ISO you will get noise, but from the few shots I have taken on higher settings it does not put me off. The weather and conditions determine how you set the camera up, and force you down that route, but in saying that I suppose if one was taking shots of something that important, then you would have all the lighting gear at your disposal and not have to worry about using such high ISO speeds :shrug:
 
Well its with wildlife, and I havent got the longest lens in the world, so my images require cropping quite often, and I guess thats where it notices.

Don't quite fancy setting up lighting for wildlife though :lol:;)
 
Can I confirm that switching off the settings we're discussing applies to RAW only, or would it be good to customise the custom functions as above for both jpeg and RAW shooting? I shoot with both. Just trying to understand how the C functions work; am kinda new to this level of camera! :thinking: :naughty:

Hi Sarah,

I read in a photographic magazine review on the 40d and 50d and it said that up to 1600 ISO they were about level, but any higher and the 40d performed better than the 50d.

For that reason I have held out so far as to which camera to buy.

Regards,

john

The reason I think is because the default setting are on and to get best they need to be OFF this was not known very much to start with. So Test might have not turned them off.

:lol::lol: you and me both girl :D 70-200 with a 1.4 TC is my arsenal at the moment, ok there are obviously some shots you are not going to get, but then again that is where I think the enjoyment of fieldcraft comes in. The way I see it is like this, I am stuck with what I have at the moment and for the foreseeable future. My intentions are like many I suspect and that is to tick off as many different species that I can, and to date that is very few, about a dozen at a wild guess. So instead of aiming for birds that I know I could not photograph without the right equipment ie: Species that live on the other side of the island in a lake, I try and concentrate on those nearer to home. That way I still have something to aim for. Spotted some Redwings yesterday picking the berries of the trees, it was in someones garden, but when I knock on their door and explain my hobby and ask for permission to sit up one day in the garden, the majority of people are quite obliging.
 
That's good to know. However...

Is the issue we're discussing regarding RAW shooting only, i.e. the NR settings, ALO, HTP etc are specifically for the enhancement of jpeg shooting??

Thanks :thumbs:

Not sure i believe this. (not suggesting your talking rubbish, but whoever said that)

Ive just got a 50d as a second body, and the iso performance is worlds ahead than the 40d (my other body)

I have used my 50d for about 1 week (albeit ive been borrowing one for a few months) and i can say there is a massive difference. Otherwise i wouldnt have bothered and bought a 2nd 40d and saved £200.

Maybe im just seeing things, But i would swear this is the case.

However there is still certainly room for improvement over the 50d.
 
Noise is the least oif my worries with either the 50D or the 7D. I habitually shoot at 800 ISO, quite regularly at 1600 ISO and wouldn't think twice about going to 3200 ISO if I needed to with either camera. The nice thing about these high pixel density cameras is that any noise tends to be in oof or plain areas of the bg, with the feather detail retainng sufficient detail that noise is either invisible or negilible..

Couple of shots from today....

Dunnock Full Frame at 800 ISO

4095634152_846f9cc73b_o.jpg


And a mahoosive crop by any standards. I've run NR just on the BG in this shot but it really wasn't objectionable anyway even at that large a crop. OK it's not brilliant but it's plenty good enough for web use.

Rubin shot Full Frame at 1600 ISO

4095634364_7c7ca7e644_o.jpg


A fairly substantial crop with no NR at all on this one.

Very good results. :thumbs:
 
Robin shot's lovely Cedric :)

Is your NR process, run it in in NoiseNinja then rub back the bits you don't want NR run on? cheers

No - but thinking about it - that would work as long as you applied the NR on a layer. It would involve some fairly careful fiddly rubbing out though Drew.

What I do is select the bg with the magic wand .Hold down Shift on the keyboard and just keep clicking on the bg until you have a tight mask around the bird witht he whole BG selected. Then apply NR just within the mask. Once you've done that you can invert the mask and sharpen the bird selectively.

I use Paint Shop Pro which has it's own NR filters.

That's correct - having either setting enabled in RAW aggravates noise.

gotcha, thanks - i use photoshop everyday (3d artist) so am used to brushing/painting things with the mouse, always nice to see how others' do it though :thumbs:

cheers

Well the magic wand method is a lot quicker than you might think. With practice a lot of even quite busy bg's can be selected in a couple of minutes. As long as you keep shift depressed you can swap to any other mask tool you like and select very tricky busy bits with the lasso tool or any freehand mask tool. Once you have a complete mask don't feather it - it will look weird.
