Is that amount of "snow-like" noise normal for 7D? Sample images inside

[SelNZ]

Just clean black boxes here.

I honestly do not understand what it is about some people - quite a few in this thread - which makes them want to stand up and declare that because they can't see something, it isn't there. Like some weird parallel with Schrodinger, if you can't see it then it hasn't happened.

whew, what side of the bed did you fall out of today. I never said it wasn't there. What I said was "I" couldn't see it. In fact if you printed it in a large format I doubt if you could see it. For normal viewing on the internet I doubt you would see it.

Maybe it's me, but yes I have had a few stupid people to deal with today, not all of them online. Doesn't really change what can clearly be seen in those images though.

What I said was "I" couldn't see it. In fact if you printed it in a large format I doubt if you could see it. For normal viewing on the internet I doubt you would see it.

Let's not forget where we started - a guy innocently posts a question asking whether this type/amount of noise was normal for his new camera, and I replied with yes, it's normal, and an image to show him that mine's the same. It could quite easily have ended there.

Then the forum idiots started posting that what he and I could plainly see, wasn't there. So I have to post again to demonstrate that what I said was correct - and I start to look like I'm being obsessive about some faint noise in black frames at ISO 3200. I'm not, I'm saying it's normal, while also having to deal with the idiots who say it's not there.

You said, and I quote, "You must have your monitor set abnormally bright" and "Just clean black boxes here" - yet another accusation that those of us who can see an 18% grey pixel on a jet black background are the ones at fault. So take your seat over there with the rest of them.

Methinks you are reading things into what people say. Not a good way to make friends. Maybe some anger or paranoia management therapy might help.

"You must have your monitor set abnormally bright" is plain English, not really open to "reading things into". I can see an 18% grey pixel on my calibrated monitor, and you can't see an 18% grey pixel on yours. Yep, clearly it's me that needs help.

When you've calibrated your monitor and invested in a pair of reading glasses (which I wear - maybe that's the difference?) then I'll be happy to accept your apology, even after the patronising remarks.

Yes, the specs are quite apparent in the darker areas of real-world pictures, like those from the xmas market I made.

OMG! The sensor of the Hubble space telescope (I presume) has some horrible high ISO performance!

This started out with me offering constructive help to a fellow poster who I am pleased to be able to say has benefited from it. But ignorant people like you make me wonder whether it is worth the grief.

I tend to like my monitor's brightness setting on the conservative side....not bright... and I can see the spots as well. What they mean, I don't know.

I know you mean well but please do not embed my images into the forum. Thanks for respecting that.

I can't give you a highly technical answer to that, but they are basically electrical noise.

 

[PC Wheeler]

I would like to have your input on whether this amount of white specs is normal for this camera model or not. If other 7D owners could post pictures created with the same test setup (i.e. ISO 1600 and 3200,

Those look great to me, very clean.

That is why they want to sink it into the Pacific.

I do not recommend doing the same with your 7D however, unless US governemnt would buy you a brand new 1DMk4 or at least a 5DMk2.

So why did you pick on me? You don't know me or anything about me. All I did was offer an opinion that happened not to agree with yours. The OP could take it anyway they like.

I tell you what Steve. Since it seems to mean so much to you and I don't care two hoots what you think of me. You win

I would crush that defective body with a hammer immediately.

No no no, we already determined it's got to be faulty monitors, so everyone that had a hard time seeing it.... nuke your monitor! Be sure to use a BFH, big ((insert curse word)) hammer.

 

[jm67]

Yeah, Steve, I hear ya. I did the same thing myself. I opened the "pic" in photoshop and started wiggling around the cursor with the info tab open and lo and behold there were spots of significant brightness. I thought I was seeing red spots but lo and behold photoshop told me they really existed.

I was considering a post like the one you did but gave it up as commenting on people's monitor calibration/brightness/darkness is like commenting on the performance of certain body parts. So some of us can see it, some can't, some think my monitor's "off". Oh well.

Just wanted to let you know I too see 18% spots. Now if I start seeing ghosts...then I'll be concerned.

I have no problems seeing them on a 12" laptop monitor.

(Hey, this is photography at its best, don't you think? ;-))

It is pixel peeping ats its best and has imho nothing to do with photography.

While I admittedly sometimes have a nasty pixel peeping tendency, in this case I would not speak of pixel peeping, as this noise is visible when viewing images full-screen (i.e., not zoomed in) on a (properly set-up) 24" monitor.

 

[Greg Pavlov]

You can see it in dark areas in full-size photos posted on on various sites, such as the candelabra image in the 7D test set here on DPR.

Do you see this noise when you photograph something outside at night? Or in a dim room?

 

[jeansebc]

I calibrate my monitor every week with MonacoOptix xr for years and can see crearly the small white noise and bigger red one that is not uniform. the iso 3200 shot look to me like like a very busy red constellation. Lot of noise but it is randomly spread more like a film type grain. I don't see no banding pattern, so I think your camera is ok. some camera of the same series can show more or less noise.

 

[Jay S.]

All,

I'm sorry if there are more posts about this elsewhere, but I've even fed the images to Canon. JPEG Images starting at about 800 ISO show a high level of "white" dots with any increase in sharpening.

Not my monitor, tried multiple lens', etc. Canon even reviewed and said it wasn't correct, so apparently there is something to this snowiness. I'm within my two weeks of return or exchange.

Canon had me do a manual sensor cleaning and it seemed to help some (don't know why), but they are absolutely still there. Will try to post an image later..

I welcome any thoughts in the meantime though.
