Joe Marques Offline Buy and Sell: On Registered: Jan 22, 2004 Total Posts: 987 Country: United States RAW 4-way comparison This is my no means scientific. I simply processed a shot through 4 different RAW converters (WB tweaked by clicking on the shirt, levels tweaked, hilights tweaked where needed - all basic stuff done in less than 2 minutes). I purposely chose a 50 1.4 shot wide open in natural light (indoors with window light) at ISO 1600 since I was most curious about how each converted rendered noise (no noise reduction applied in converting) and WB. The software compare: Adobe Camera Raw 3.1 Canon Digital Photo Professional 1.6.1 Bibble 4.2.6 Raw Shooter Essential 1.1.2 Here's the 4-way comparison: Here's a 50% crop showing a noisy shadow area: Personally I like ACR the best although RSE is not far behind and has the best upside because it's browsing speed is the fastest and it's processing speed is second fastest (behind Bibble). HERE IS THE ORIGINAL SHOT PROCESSED STRAIGHT THROUGH ACR (NO TWEAKS) Edited by Ranger099 on May 17, 2005 at 12:19 AM GMT Edited by Ranger099 on May 17, 2005 at 10:04 PM GMT (Reason: added unprocessed shot) May 17, 2005 at 04:50 AM

My pleasure Tim. :) Note that I didn't use any noise reduction - I wanted to see how the converters RENDERED noise and ACR rendered the least color noise of the bunch. May 17, 2005 at 05:18 AM

Tim Wild Offline Image Upload: Off Registered: Nov 17, 2004 Total Posts: 1533 Country: New Zealand Re: RAW 4-way comparison I think the defaults of ACR do a little sharpening and noise reduction, but it depends how you have yours set up, or you could have turned it off. May 17, 2005 at 05:21 AM

I do turn off NR and sharpening in ACR - I like to control both aspects in PS. Thanks, Joe May 17, 2005 at 05:25 AM

Although I have not used RAW Shooter, I tend to agree that the ACR is the best unprocessed beyond where you left it, and I agree that the sharpening and other stuff is best done in PS/CS2. Thanks for posting this. May 17, 2005 at 06:20 AM

m3rocket Offline Image Upload: Off Registered: Feb 26, 2005 Total Posts: 347 Country: United States Re: RAW 4-way comparison Just keep in mind, that "as shot" mean different things to different converters. To DPP, it's the parameter settings on the camera. For RSE, camera settings are ignored, and the "default" is tweakable on a per camera, and per ISO basis. In looking at the "test," it seems fairly clear to me that ACR is doing some color noise reduction--turning off NR there probably simply turns off luminance noise reduction. May 17, 2005 at 09:39 AM

simonbaker Offline Image Upload: Off Registered: Jun 05, 2003 Total Posts: 17 Country: Germany Re: RAW 4-way comparison your tests demonstrate nicely the problem with skin shadows I have always been having with ACR. There always seems to be very little colour depth in these areas, everything resolves to 3 or 4 tones of browns or yellows. Your RSE example shows better shadow resolution, but overall the portrait is much flatter than the ACR example - something I've been seeing a lot of in my results. Otherwise I'm reasaonably impressed with the Pixmantic product. May 17, 2005 at 10:14 AM

jamesf99 Offline Buy and Sell: On Registered: Oct 09, 2004 Total Posts: 3806 Country: United States Re: RAW 4-way comparison Great test. When I first looked, the ACR was the brightest and appeared to be the "best". Now, I'm not so sure. The picture is flatter than the DPP rendering. Only you can tell us which skin/hair colors are closer to your subject's, but the skin tones of DPP look more real (albeit with somewhat of a gray cast that could be removed). Look at the right eye (on the left for those who don't know right from left :) ). There is clearly more depth in the DPP version. Jim May 17, 2005 at 01:35 PM

pchew Offline Buy and Sell: On Registered: Jun 16, 2003 Total Posts: 1249 Country: Canada Re: RAW 4-way comparison Would be interested to see a result from EVU. My own experience shows that EVU gives the best skin tone for RAW conversion. Perry May 17, 2005 at 02:03 PM

I will admit been palying around with the new Arc 3.1 and it is much better at workflow but still can use improvement there but the images are looking better The seem to have been working on colour since V1.0 (which was somewhat strange in other than flat mode).

BeeMan458 Offline Image Upload: On Registered: Mar 01, 2002 Total Posts: 7712 Country: United States Re: RAW 4-way comparison "...but what i find weird is the colors look better or more natural in RSE..." I think what you're seeing is the blue cast that has been added. Please forgive me if you find my following to be nutty thinking. Put some blue glasses on and go outside, high noon, blue skies with a few fluffy clouds in the sky. Where the glasses for a few minutes. Raise the glasses, lower the glasses and then raise them again. In my case, I became painfully aware of how much yellow/jaundice is in reflected sunlight as opposed to the blue cast we've all been taught that is natural daylight. It ain't the way we've been taught to see folks. Look at the clouds in the distance and you'll see the clouds, if the sun is out, have a bit of a yellowish/jaundice look to them as opposed to being white or grayish white as we've been taught to think of the coloration of clouds. We are clouding (no pun intended) our seeing with what we've been taught as opposed to seeing things as they really are. Please don't lock me up for what I wrote above. May 17, 2005 at 02:51 PM

The others are nice and warm. I agree they look nicer, but I think the Canon looks more realistic.?? May 17, 2005 at 03:03 PM

Sam Bennett Offline Buy and Sell: On Registered: Sep 26, 2004 Total Posts: 3593 Country: United States Re: RAW 4-way comparison For me it's all about workflow. I know that C1 and RSE can produce results close to DPP, but I've found that DPP gets me where I want to be much more quickly - basically I end up just spending a long time tweaking C1 and RSE to give me what DPP would give me by default. Bibble is a total no-go for me since it simply can't deal with super-saturated color channels in my concert photography work. May 17, 2005 at 04:28 PM

Steve Tinetti Offline Image Upload: On Registered: Jan 12, 2002 Total Posts: 867 Country: United States Re: RAW 4-way comparison I agree with Guy, a color chart would be a good idea. Perhaps even a custom white balance shot. Workflow is indeed important also. Since many images still need to some PS tweeking anyway, a converter that allows you the best combination of quality and speed might be best. With all due respect to the original poster, who specifically stated this was not scientific; this type of "test" should be conducted under more controlled conditions, to narrow the subjective to the objective, IMO. As it is, we're going back and forth based on our subjective opinions of a subjective test shot under subjective conditions. Without a known value anywhere in the shot, how can we agree on anything?

Steve Hi Steve, Thanks for the respect - this response is not a disagreement, it's just my rationale for posting. I actually chose my subject title well and called this a comparison. :) As a test it's fairly useless - as a comparison it has some value. I approach RAW conversion from a subjective perspective - I have a "look" I want to achieve based on how I saw the shot when captured and a "time value" relating to the effort it takes to achieve that look. I showed this comparison of my basic "quick conversion" using as many pre-sets as possible to get a good result. I subjectively find ACR the best output but RSE the easiest to achieve "close enough". I do like your idea of a controlled test and I will do so with a GM color chart because I too am curious how each converter handles WB by clicking a color patch. It will also provide objectivity for a entirely different evaluation of RAW converters. Thanks for posting. May 17, 2005 at 06:25 PM

Are you sure you weren't using the default settings in ACR, which is +25 for Color Noise? If this is a Canon CMOS sensor, I doubt that CNR wasn't on, looking at the ACR example...

My mistake. I ALWAYS turn off CNR but missed it on this shot (I just ran the file through ACR and it's clear that my comparison result had CNR +25). Sorry for any confusion. As I mentioned above - I'm actually going to re-do this as a more formal test with tight controls. :) May 17, 2005 at 07:21 PM

mateo_ Offline Image Upload: On Registered: Jan 28, 2004 Total Posts: 688 Country: United States Re: RAW 4-way comparison What curve did you use in Bibble? I find the default oversaturated look unuseable, but w/ the colorimetric curve it matches C1's and RSE's look, and becomes the best RAW converter for me to work with. May 17, 2005 at 09:11 PM

OK, dumb dumb question here :D +25 color noise means adding color noise by 25%? May 17, 2005 at 09:20 PM

Monito Offline Image Upload: Off Registered: Jan 28, 2005 Total Posts: 5429 Country: United States Re: RAW 4-way comparison Tight controls would not include "clicking on the shirt" to set the white balance. The shirt is patterned. Even if it were not, a pixel or two over will give you a different white balance. It is impossible to get consistency that way. May 18, 2005 at 12:19 AM
