7Dii "Noise" - Imaging Resource raw files

I downloaded the "House" image CR2 files from 100 to 12,800 ISO; & checked them in 3 raw Converters; Photoshop CS-6/ACR, Photo Ninja, & DPP-3.14.15.

All 3 programs had all/any NR, & Sharpening "shut off".

With ACR, there was a "fair" amount of noise at 1600, & at 3200 it was in the "barely acceptable" range. while I didn't expect results equal to my 6D, though the noise was manageable, I was somewhat disappointed.

In DPP-3, however, there was a "night & day" difference, with much cleaner results, to the degree that ISO 3200 files looked nearly as clean as 800 ISO files in ACR?

I'm not sure what's making the difference, but the files in ACR opened with some "strong" black clipping that needed correcting; whereas in DPP-3 there was no apparent clipping.

Going by the DPP results, it appears that the 7Dii can do quite well at ISO 3200!

I wondered what results others are finding?

IMO - you'll get a better idea about the images once the RAW converters are updated with the New Camera profiles. Until then - why bother

^This.

Why play with raw files before the camera's profile is in the raw converter??

Since he wanted to look at the amount of noise, and had NR and sharpening set to off, why should the camera profile be useful then?

Significantly improved "High" ISO noise performance over my 7D's is my primary consideration for upgrading.

There's no reason why a basic evaluation of noise performance shouldn't be performed using the "Standard" profile/s.

In this case, the ISO 3200 shot, in DPP-3 was quite promising-----. I would think, if anything, the actual 7Dii profile may improve it further-----Certainly not make it worse.

Because raw formats change, there have been probably 3-4 different raw formats from Canon alone in the past several years. The 3rd party tools need their developers to reverse engineer the raw data and make changes to their versions of raw converter routines. Canon does this automatically with DPP updates.

Here is a direct out of DPP from raw JPG at 3200 on a 7D in low light. How does the noise characteristics with what you did compare to this?

Here is 6400

To show copy variation, here is another 6400 untouched once out of DPP, but from a different body.

The only way to acquire valid noise comparisons between two different camera bodies would be to shoot the exact same scene, with the exact same settings.

The difference is not what either body can do with "bright", evenly lit scenes; but what it can do with "dimly" lit scenes with "harsh" shadows.

I know that intimately, that is why I supplied VERY low light samples (f2.8, ISO 3200, 1/80th). I assume the samples you pulled for the 7D2 wasn't in low light then. One can compare the noise characteristics between 2 different scenes however, just not the quantity of noise.

In most cases until the raw converters are updated they are just displaying the embedded jpg.

If you are using raw therapee you can pick an appropriate profile. It will look pretty close to correct--we'll have to see how diff the color filters are vs the 70d and such.

It surely must be a terrible product then. ...Based on an image review of a camera that is not available yet, nor conversion profiles. And the moon is made of cheese.

Probably user error, but I couldn't find the "house" image in the 7DII Imaging Resource samples available as of 8:00 p.m. EDT September 18, and DPP 3.14.15 wouldn't open the .CR2 file I downloaded from their standard test image samples. Any thoughts on what I'm missing here?

EDIT: A little Google helped me find DPP 4, which apparently is needed to open 7DII RAW files. I haven't been able to download it; as best I can tell, it's only available from non-US Canon sites and is tied to specific camera models, requiring a serial number from one of those models to download. Unfortunately for me, the 7D I have is not one of those types.

Use any serial number you find in google images of a 5D3....

Excellent - thanks!
