350D high ISO samples... Real world use

Its been more than 2 years since I have had my 350D or the Rebel XT as its known in many parts of the world

I am posting some shots taken at ISO 1600, and many of them are with nifty fifty at 1.8
Owl ISO 1600 1/30 F1.8



Another owl ISO 1600 1/100 F1.8



Animal show ISO 1600 F1.8 1/20s



Leopard eating Meat ISO1600 F1.8 1/80



Rhino ISO1600 F1.8 1/250



Now a couple of ISO 800 shots with 75-300 USM III lens
Dolphin - ISO800 F5.6 155mm



Dolphin F4.5 ISO800 75mm



ISO 1600 shot Blue and red with kit lens F4.5 at 35mm



The 350D 8MP is one gem of a sensor. Infact I am afraid to upgrade. Will any other sensor(even from canon) allow me to crank up ISO at will?

I don't own any photoshop etc., and use GIMP mostly nowadays. Only noise reduction is DPP built in, and I have found it useful for removing hot pixels.

No other sensor, only the full size Canon CMOS.
Nice pict, are you the marketing person for Canon?

Great photos. Great camera and sensor. I think you will find the XS/XSi also do a great job at high ISO, possibly a touch better.

Glad you are enjoying your camera

Infact, if canon tries to shove a 15MP APS-C down my throat in the 500D, I may jump ship to some other manufacturer

Better examples than what I have experienced with my XT. Of course, I would love to see some large high resolution examples straight from the camera as well.

I have never been a fan of 1600 ISO on the XT and is personally my 2nd biggest reason for wanting to "upgrade"

I have never tried anything beyond ISO 400 with my XT but till that point it has given some decent results. But it has been a great camera for me. I would love to upgrade to the 5D MkII but I will wait for a few months while it is tried and tested and hopefully some price corrections happen.

Here is a sample at ISO 400.

I've shot 1600 iso with the 350D on many occasion and use it whenever it's needed without hesitation. If you properly expose it and shoot raw, use a noise reduction app it can give very usable results.

Here's one full resolution processed raw shot at 1600 iso and 85mm f/1.8 at f/2.8:

Here's the raw file, you can use your favorite workflow to compare:

I have many more examples with a variety of shooting conditions with similar results. If you print up to 20x30cm (8x10") you won't notice any noise. I've printed a 800 iso shot at 75x50 and it looked very good, very little noise was noticeable.

On screen viewing is different matter though, screens have much higher contrast than print so it will show it much more readily. But with careful processing it can be kept to a minimum. Process your image as usual, turn off any sharpening and noise reduction. Use neat image (default gives acceptable results) then resize to your screen pixel size, then sharpen using usm 300, 0.3, 0. It should look very good. You can enhance it even more by masking out any detailless areas like bokeh, smooth surfaces etc.

My XT is still going strong.

I barely look at this forum anymore for that matter. There are so many newer models of the 350D already, and crazy opinions, whats the point.

I did get a 40D a while back and it's okay. I got it during an Amazon $899 & free shipping sale. At first the speed and better viewfinder wowed me immensely. Now that the new is worn off, it's just another DSLR. The pictures are no better than the 350D, just a little faster & easier focus.

I wouldn't buy any Canon DSLR at this point. There is nothing available for a decent price that is really going to be any upgrade. When the 50D replacement has movie mode, or the 5DII comes way down it cost, I would like to have that feature.

I've never hesitated to use it if that is what I need to get the picture.

We will not have a problems about those noise at ISO 1600, anyway we have noise ninja (software for noise elimination).

You're right, it's really good at ISO1600 - so is my old 20D. I won't be upgrading either of these cameras unless I'm sure I'm going to get even better noise performance.

Here's one with the 350D. Taken in RAW using 35 f/2 @ f/2.2, no noise reduction, selective sharpening. ISO1600, 1/25 second.

Wow, that sample you included is much cleaner than anything I have ever seen from my XT. That is probably cleaner than anything I get at 800 ISO as well.

What kind of noise reduction application do you suggest? I hear a lot of people suggest noise ninja, and I downloaded the trial version one time but was very unsatisfied with how much softer my images were after running it, much less noise but they were softer. Of course I could have been doing something wrong in the first place.

Thanks Joey, I mainly use Neat Image. I've used Noise Ninja in the past but it could sometimes not be 'convinced' to take out certain patches of noise. The good thing about noise ninja is that you can use small parts to build up a profile which can be handy when no large continuous patch is available. Neat Image works from only one large sample and can take out low frequency noise as well as patterns.

I turn down noise removal on luminance to about 35 for iso 100-400, 50 for 800 and about 60 for 1600. I also decrease chroma noise a little.

I've manually selected the largest patch I could make here and then hit auto profile:



In the next tab (noise filter settings) select a part to test the noise reduction, zoom in to 200-400%. you can activate the component viewer (4 colored disks icon) to check how it's affecting the image per channel. Left click to see the original vs the reduced one. Adjust the sliders on the right in advanced mode. Noise levels will make the effect stronger or less so while noise reduction amounts will mix the original and the reduced version. 100% luninance removal looks platic, 60% about the highest you can get away with. I don't mind a little noise so I tend to set it lower. But increase it if you intend to use a lot of sharpening (which increases noise).



On this image I think I've done it too quick as there's still a lot of residue noise that can be filtered more effectively if I had more time. With the settings above and some selective (using masks) sharpening I'd be able to print at 75x50cm (30x20") without seeing noise.

Shooting in natural daylight greatly improves noise as does shooting to the right of the histogram. In this shot it really helped that the subject was bright (no dark skin or black hair).

But I've also shot in less than ideal light and had acceptable results. This one for example. Processed in raw image task in zoombrowser, no sharpening or noise reduction (no option for that for 350D in RIT). It printed at 30x20 (8x12") with no discernible noise and looked great.

Both noise ninja and neat image improve constantly. If it's been a while I'd try both latest versions and see what it does for you. Noise ware is also a good one I hear but I never tried it. It keeps popping up in the retouch forum so it must be good

I seldom use ISO 1600 with my 350D, but it is reassuring to know that I can if needed. Since I mostly shoot landscapes, I use a tripod when light conditions are not good. Here is an exception that I took at ISO 800.
