CR2 to JPEG: DPP vs ACR (adobe) - UGLY!

[cyber3d]

I just noticed something weird. May be someone can shed some light on this problem.

Created a JPG from a CR2 image (Canon 60D) using the latest versions of DPP and Photoshop CS5 (ACR). But on close inspection the DPP image has these really ugly artifacts. On the other hand when processed in Photoshop there are no artifacts.

CR2 > JPG via Digital photo Professional


CR2 > JPG via Adobe Camera Raw plug in

Made sure they were both set to the same jpg quality? (Sometimes it's the simplest of things that get overlooked and ya wanna smack yerself upside the head with a sledgehammer when ya ask yerself "Why didn't I SEE that?" Maybe that's not the case here but if it WAS something that simple, don't feel bad; it happens to us all.)

Are you saying you went from cr2>Jpg, then opened and worked on the jpg in PS, then saved the jpg again.?
Why not open the cr2 in DPP, then click send to Photoshop, work on the tiff, then save jpg when it's done. The more you open, manipulate, and save jpgs, the worse they get.

No, actually. I didn't reprocess the JPG image. "And don't try that at home kids!"

The original CR2 (straight from the Canon) was brought into DPP converted to monochrome and saved as JPG (Exif-JPEG (the only jpeg option), image quality 10 (max), 350 dpi, no resize) and saved as a the JPG you see.

The same original CR2 (straight from the Canon) was brought into PSD, desaturated into monochrome via ACR 6.4.1 and saved as JPG image quality 10 (max), no resize.

I've tried this on several images and it is pretty consistent. DPP's JPG conversion pretty much sucks.

Can anyone try this?

In camera raw it only gives you the option of saving jpg quality 10 but if you type in 12 it will save as quality 12 which is available in 'save for web' just a thought

On a side note the software that came with my Canon crashed two computers and left me 'up a creek' I love my Canon but will never try any of their software EVER again

Sorry I don't have an answer to your question, but why are you going from CR2 to jpeg? You would be better off going to TIFF or PSD and only converting to jpeg when uploading to the web.

I would also recommend sticking with ACR if you do have it.

download a trial of lightroom and run it through the noise reduction slider. Get rid of the noise in the RAW file, do your contrast, and BW conversion in LR, then do the rest as a TIFF file.

Just a thought. You have a tight crop on what likes like a obscure corner stage rig. Are you being relistic in trying to get everything perfect.

Don't know about being realistic. But, the observation startled me. IMO, artifacts are artifacts and are on some level perceptible to the eye - even with a full size image. I would think it is an issue for some photographers. For those who don't use a medium format camera and have to eek out as much quality as possible from a little ASP-C sensor to be competitive. (I am not a Pro, BTW).

I did not think to manually change the DPP Jpeg value from 10 to 12 - I'll try that. Personally, I liked DPP for all it's features. But, that engine made me think twice. I've had PSD since the original version (and now CS5 with the latest ACR) and know it well. However, for my workflow process, DPP could become my mainstay program (if this issue can be resolved).

Thanks guys.

What a shame. DPP does not allow you to choose the level of compression when saving as a jpeg. 10 is the max.

I'm using the lastest upgrade of DPP - version 3.10.20

So, the rule is: "never save as a jpeg in DPP"
