Canon 7D noise

I am using 5.6 "release candidate" on CS4 for my Canon 7D. It works okay, but my photos seem a bit "noisy" for the low 200 ASA. Anyone with similar problems?

1. Was Highlight Tone Priority turned on?
2. Have you applied some sharpening without noise reduction? Try it with color NR=25.
The 7D's noise on pixel level with lower ISOs is quite higher than the 40D and a bit higher than the 50D, but it should not be striking with proper processing, and the higher pixel count should make up for that.

Lightroom, Canon 7D, Noise

I notice that there is a lot of noise in my images shot at 200iso. It seems to be more noticeable in Lightroom than in Photoshop CS5. I just got the 7D 2 weeks ago. Has anyone else noticed this?? or is there a problem with the 7D processor?

Thanks, Lee Jay. Does that mean that I need to be in the develop module and move the slider up for color noise reduction? or is there something else I have to do to turn on the noise reduction??
Thank you for any info

How do you guys reduce noise in Canon 5d mark II video?

I am really interested to know if anybody could give me leads on how to reduce noise in 5d mark II videos. First off - Canon 5d mark II stock HD bitrate is not really nice. Even shooting in day time I have color noise and a lot of noise in shadow areas. Its only after I played with ML 2.3 and tried to shoot 1080p vid on CBR 1.4x mode (thats the maximum bitrate supported by my present CF card but planning to buy a new one).
How do you guys deal with it?

Tests have been done that show ISO settings in multiples of 160 produce the least amount of noise on video. Starting at 160 the 5Dmkii produces less noise than even at lower ISO settings of even 100 ISO. 160, 320, 480(500), 640 and so on. If you need ISO settings of a lot higher and the noise becomes obvious there is video noise reduction software that could help.

Poor quality noise reduction for Canon G10

I recently bought a Canon G10, and I am disappointed at the quality of RAW conversions done by ACR/LR at anything approaching a high ISO. The out-of-camera JPEGs show much superior noise reduction to what I can get from RAW files, no matter how I tweak the noise reduction settings.
At ISO 80-100 both look essentially identical.
At ISO200 JPEGs show less and tighter grain than I can manage with RAW (unless I nuke the details with luminance reduction), but both are still very good.
At ISO400 ACR/LR's RAW conversion starts to fall apart. Chroma NR in RAW is still handled well, the grain size in RAW is much larger than the camera's JPEGs. I need to apply a lot of luminance NR to reduce the RAW grain to match the JPEGs, and when I do that I lose a lot of detail. And even then, the larger grain isn't as attractive as the JPEG.
At ISO800 this problem is even worse. Big ugly blobs abound in the RAW conversion. The JPEGs don't look great, but they're very usable, especially if you're willing to dip the shadows a bit to hide the worst of the noise.
ISO1600 is interesting. The JPEGs don't look great; there's a healthy amount of noise, and NR kills a lot of fine details. But the image is usable for 4x6's or sometimes even an 8x10. But the RAW files are awful! Even cranking chroma NR to 100, there's color noise to be seen. And even with very careful use of luminance NR and sharpening I can't results that are anywhere close to JPEG's level of detail and noise.
I understand that P&S cameras like the G10 are very noisy by DSLR standards and so this might not be a focal point of ACR/LR development, but I'm surprised and disappointed that the JPEG engine in the G10 can do a better job handling noise than ACR/LR. I guess my hope is that ACR/LR will at some point offer improved NR so I can create photos using RAW that look as good as JPEGs straight out of the camera. As it is right now I'm in the unfortunate position of shooting JPEG at high ISO to get usable noise performance. My dilemma is whether to even bother shooting RAW+JPEG when this IQ might be the best I ever get from ACR/LR for the G10.
I suppose my favored solution would be to either implement or license NR technology that matches NeatImage/NoiseNinja/NoiseWare. That feature alone would be worthy of justifying a 3.0 version for me. :)

Jeff, I won't debate that the output from the G10 at ISO800+ is poor. It most certainly is! And I know that simply eliminating the scads of noise in a G10 high ISO shot won't restore the detail the noise killed in the first place. But with every other camera I've used with ACR and LR, the color noise slider eliminates all color noise at or before the "100" setting. So I was surprised when that wasn't possible with the G10.
I don't currently own a camera that puts out an image quite as noisy as the G10 at ISO1600, but what about the A900 at ISO6400?
http://www.imaging-resource.com/PRODS/AA900/AA900hLL6407XNR.HTM
Or the 50D at ISO12800?
http://www.imaging-resource.com/PRODS/E50D/E50DLL12807XNR.HTM
Both of those are horrifically noisy. Worse than the G10 at ISO1600, I'd say. But those cameras certainly aren't crap. They just offer ISO settings higher than some consider acceptable. But then again, some people consider anything higher than ISO200 on a 5D unacceptable, so it's obviously all relative. Point being, I would expect ACR to do the best job it could for any camera it supports, not just the best job it can do for only some of the cameras it supports.
In any case, I want ACR to be able to remove the color noise from my G10's images, just like it can with my other cameras. I know the images are sub-standard when measured against a DSLR, but at least to my eyes, even very noisy images can look decent in small prints so long as there aren't big color blobs all over the place.
As for the luminance noise, I'm happier to live with that. I'd be happy to eventually pay for a LR upgrade that gives me NR similar to what the high-end third-party apps do, because that feature would make each of my cameras geniunely more useful--and retroactively! But a simpler request it seems is to recalibrate what "100" means for the G10. At least then I could dispense with the JPEGs and still make an 8x10.

How to fix noise problem with Canon sx50 HS

I'm wondering why are all of my videos I record with my Canon sx50 HS so noisy as in fuzzy not sound. No matter how I change my Aperture, Iso, Shutter speed, it still doesn't make much of a difference. I still see noise throughout my videos. I have a room where my lights are good, 75 volts and I still can't get rid of it. Can anyone personally help with this issue?

For starters, I don't know how good of video is possible with the sx50. It's a compact camera, so there will be limits.
As to the noise and/or fuzziness. Depends on if it's noise, or fuzziness, but I suspect both would be caused by the same thing - lack of light. Photography/videography takes a surprising amount of light. When you're indoors you need a surprising amount of bright lights for good picture. I'm not sure what you mean by 75 volts, but a 75 watt light isn't bright at all, not for a camera. How does the video look if you shoot outdoor?
If a camera doesn't get enough light it's going to do three things - open up the aperture, raise the ISO, and increase the shutter speed. Raising ISO adds noise, plain and simple. Opening the aperture can reduce the amount of the photo that will be in focus, making things look fuzzy. And increasing the shutter speed can allow movement to show, also making things fuzzy. Without seeing your video it's hard to speculate which it is.

Canon 5D2 ACR chroma/luminance noise reduction

Admitting to being somewhat lazy w/respect to experimentation, can anyone recommend chroma/luminance noise reduction settings in ACR for the 5D2, as a function of ISO?

Well, if we deal with the subject here at this level of details, then I need to add some points:
1. For the advanced digital photographer: if a lower ISO is enough for a correct exposure, but one is aiming at achieving "exposure to the right", then it is useful to turn up the ISO
i without reducing the exposure
in order to "get to the right edge".
2. Mitigating the above: the vast majority of cameras do not have true 1/3 stop ISO steps, i.e. there is no analog gain associated with the 1/3 steps; they are achieved by numeric manipulation of the nearest (lower or higher) full stop ISO result. For example from the Canons, only the 1Dxxx models support real 1/3 step ISOs.
There is no point of using these ISO steps with raw data.
3. Almost all cameras offer high ISOs, which are fake, i.e. numerical derivations of lower ISOs; in some cases they are
b not only
those characterized as "High", "Extention", etc. For example ISO 12800 and 25600 are marked as "high" with the Canon 5DMkII, but in reality already 6400 is fake.
There is no point of using these ISO steps with raw data (yes, I wrote this already).
4. The top
b useful
ISO is usually even lower. For example the graphs in http://www.panopeeper.com/Demo/Canon5DMkII_Noise.GIF show, that the loss from 1600 to 3200 with the 5DMkII is precisely one stop, i.e. there is no point to use ISO 3200 with raw data. Some other cameras can not utilize even lower ISO settings in raw (the usefulness of those settings is when recording JPEG in-camera).
Using those ineffective ISO steps causes cutting off the one stop of the dynamic range with each ISO stop.
This is an ACR forum, thus these issues are off-topic, but so much can be perhaps tolerated.

Canon XA10 and XA20 audio noise

Hello,
I work with a Canon XA10 and Canon XA20. Both seem to pick up a fair amount of audio noise (like a static shhhhhh), even before I connect wireless microphones. The wireless microphones just intensify it. Is it normal for Canon camcorders to pick up some audio noise? Are there settings to work with to fix this, or should I just plan to continue eliminating the noise in Adobe Audtion, or any other program you would recommend? I greatly appreciate any help you can provide.

Hello Clare27,
With regards to the camcorder picking up audio noise, the answer would be two fold: yes- as it could potentially record any noise which is present near the microphones when recording, and no- as the camcorder should not actively add static or other 'generated' type noise, such as interference. That can result from things like connections not being plugged in all the way, crossed cables, receivers and transmitters if anything like that is present.
The camcorder should be set to utilize your external microphone/s only and disabling the onboard microphone. Having the onboard microphone disabled will cut down on the chances of ambient noise being recorded. Other than that, simply having your microphones themselves set up and used properly should produce a clean signal which is recorded by the camcorder.

De-noise on iPhoto not working with Canon camera pictures

When I try to use the de-noise option in iPhoto on some pictures taken with a professional camera (Canon), it does not de-noise the picture.
I tried diffrent stuff to see what works and what does not:
- If I use a picture taken from iPhone / iPad, in iPhoto de-noise works
- If I take a professional picture, send it to my iPhone and resend it on my Mac, the de-noise will work
- If I use a professional picture on my Mac desktop, de-noise works as well.
Just not in that initial circumstance ... Strange !! Help ?!

How does this
When I try to use the de-noise option in iPhoto on some pictures taken with a professional camera (Canon), it does not de-noise the picture
differ from this?
- If I use a professional picture on my Mac desktop, de-noise works as well.

A2500 canon video recording and noise

hello I get new a2500 canon it is very good picture.but when i recording hd video a very low noise is hearing .is it normal?or not?
thank

It has nothing to do with low light at least not in my case. I'm returning it to Apple, I think it's a bad speaker as I ran the memo app in a quiet room (Didn't say anything) and on playback it still made the sound (A shhhhhhhh sound)
Guess I got a bad one

My Canon MX860 stop to copy,fax or anything. It make a noise like stripping gears. Please help!!!

Canon 6d needs lots of luminance noise reduction at all ISO settings

Hi all,
I've been trying out LR 5.4 with a new Canon 6d. I've noticed a lot of what appears to be luminance noise even with photos taken at ISO 100, this requires the "Luminance" slider in the "Noise Reduction" develop setting to be at around 80 to remove. This seems extremely high for ISO 100 photos with shutter at 1/1000 and obviously good light, I wouldn't expect to have to use any NR in this situation. Oddly, pretty much the same level of luminance NR will also clean up high ISO photos, I'd have expected to need a lot more NR on high ISO photos. Some sharpening is then required as usual.
The luminance setting of around 80 gives the photos a similar look to those from the out of camera jpeg, or the cr2 file processed in DPP.
Has anyone else observed this when processing raw file from a Canon 6d in LR? Or maybe there's a setting somewhere that I've missed?
Thanks in advance

Hi,
Thank you for replying. Hopefully there are some images attached to this post, it's the first time I've posted here...
The shots are of an area of very clear sky with the stalk of a plant in the foreground.. There is a 1:1 compare of the LR default import (right) compared to my luminance and sharpening adjustments (left). There's also a 2:1 compare to show the noise a little better. I've added a shot of the detail panel with my adjustments.
Thanks,
Paul

Aperture RAW conversion colour noise with Canon 1D Mark II

I'm using Aperture 2.1 and am wondering if anyone here is having this problem - basically highlights end up with false colour with this camera/RAW conversion combination. The problems appears to have been introduced with the 1.1 RAW converter as 1.0 conversions don't seem to have the problem. I'm not sure if this is camera specific, or whether there is some tuning which can be done to the RAW converter to minimise the effect - attempts have so far failed with this approach.
The best subject to produce the effect is strong reflections from water - i've attached a crop of an image which shows this problem, and I can supply a RAW with this problem.
Conversion using RAW 1.0 (less or no colour pixelation):
http://www.loftsoft.co.uk/pictures/KC7U5116%20-%20RAW%201.0.jpg
Conversion using RAW 2.0 (colour pixelation):
http://www.loftsoft.co.uk/pictures/KC7U5116%20-%20RAW%202.0.jpg
Any suggestions as to what to do? Is this simply a RAW conversion problem which can be addressed or am I using the tool wrong?
Many thanks,
Cesare

Hmm. I can see some color effects in the 1.0 conversion as well.
Those are some touch photos... you have lots of specular highlights with the sun reflecting off the water and the railing.
Aperture 2.x and 1.x handle the RAW conversion differently. I would suggest you try playing with the RAW Fine Tuning brick, specifically with the Moire and Radius sliders, and try fiddling with the Auto Noise Compensation checkbox.
I don't know whether you'll be able to make the problem go away completely or not.
With my ~30,000 1D Mark II files I've seen something similar to this (though much less extreme) on a couple of them. Always with specular highlights though -- off water or metal objects.
Still, you may wish to submit Aperture feedback and include the RAW file.

I have the Canon T5i and when I shoot videoat night with a good deal of light I get a lot of noise.

I shoot at night with a lot of source light, I get a lot of noise in the video. I have all the settings on automatic. What should I do to get rid of all the video image noise?

Hi mrmyth!
Thanks for posting.
When you shoot in lower light, even at night with artificial light sources, the camera may need to use a higher ISO speed. Higher ISO speeds help with exposure, but they can produce higher noise levels. Do you know what ISO speed your camera was using?
