Hi, here is a 100% screenshot of an image developed in HU and ACR. I have tried to get a similar look, and developed to native 12MP size. Afterwards the same slight amount of USM strength 100, radius 0,3.

I don't say (for now) which is which, however I was a bit surprised to see that the differences apparently have become quite small. Maybe you can guess which is which, I will tell you later.

Here is the overview - entry zone of the Berlin dome



These are the crops:

Although I think the image on the left has slightly more shadow detail, I'm going to guess that the image on the right is the HU image. The main difference I see is the magenta fringe, I guess it is, along the horizontal edges toward the top of the left-hand version.

My take is also the same

Based upon the very slightly warmer and very slightly softer rendition on the right, I am guessing that this is HU and the left is ACR.

You did very well with making the two have a similar look.

This is fun and all, but wouldn't the test be more instructive if you attempted to squeeze the best out of each conversion, rather than striving to make them look alike?

I have been experimenting with ACR conversions to the maximum 25 mega pixel interpolation size, sharpening there, then downsizing to the target resolution. I also no longer sharpen during raw conversion (I can tell from your settings that you don't either). The settings in the raw converter are too limited and coarse. In fact my latest conversions have not been getting any traditional sharpening at all, just "local contrast" boost in two stages, but my approach will vary with the subject and the effect I want.

I must say I did not really try much to make them look alike, just a little bit contrast tweaking because HU looked more contrasty in the first place. That was my point actually that I was amazed how similar ACR has become to HU. I can no longer discover a meaningful advantage of fine detail in HU, even noise difference is not huge, only a slight trace.

Yes the main difference I have seen is CA which strange enough was not there in HU (no removal) while it was there in ACR.

So the solution is.....

(nex posting for all)
 
The first who tried were all right, HU on the right, ACR on the left. Thank you for trying...

Slight traces of CA apart, for workflow reasons I would, in the future, more easily choose ACR for a much faster workflow. HU is a pain to adjust, to wait for etc. Changeing any parameter by one click starts a new preview rendering cycle which take 3 times longer than I would like.

Anyway, there was a sort of review about ACR's new version earlier that year and I now agree that the demosaicing has been made better quite a bit. Should they manage to reduce the noise further that is created during the conversion ACR could step up at the level of the best RAW converters. As far as I remember it's procesing is identical to LR....

regards, Bernie
 
Bernie,

My workflow is Convert in HU, Import TIFF into Lightroom for tweaking and file management and, then, Photoshop CS2 for anything else needed that Lightroom can't handle(masking and compositing, art effects, etc.).

I have observed some difference in yellow/orange color rendering and tonal graduation. The following image is the comparison with HU on the right. HU conversion was not tweaked in Lightroom or CS2.



There is even a more noticeable difference in prints out of Lightroom, or any other image print software.

Interesting
 
Color, depth of tones, highlight and shadow detail, the things that matter? Honestly what difference in the real world this little amount of sharpness is going to make without the rest? Printing from either one of these samples isn't going to yield anything good. IMO you're missing the point why we choose to use HU over other processors if your only concern is a minor amount of sharpness.

You're being very general and vague. It has been pointed out several times that even older versions of ACR pull more DR out of the files than HU. - Anyway as far as I remember I set the tone curve to ORG or "medium soft" most of the time. So what? The purpose of my posting is exactly to show that sharpness or detail is not a valuable reason anymore to use one over the other.

If you don't explain what you mean, it is uninteresting. You somehow suggest that converting through HU required some magic know- how which only you know.

You generalize again: Who is "we" and do you know how many really use HU as their primary converter? I remember dozens of threads in this forum that talk about the real resolution in the S3/5 and how it is best pulled out of the files.

I wasn't trying to be vague, I didn't realize that your test was limited to only sharpness, your title "HU versus ACR (Photoshop) - S5 pic comparision" seems more general and encompassing as does your conclusion,

"for workflow reasons I would, in the future, more easily choose ACR for a much faster workflow. HU is a pain to adjust, to wait for etc. Changeing any parameter by one click starts a new preview rendering cycle which take 3 times longer than I would like.."

I'm sorry if I was unclear, I posed a question to you wether other qualities besides sharpness should be also considered before settling on a processor.

I'll try to clarify, I wasn't speaking about any special know how, my comment was regarding the crops. My point is that you're not going get good/different results printing a crop this size irrespective of processor.

I'm not generalizing, "we" are the people who use HU as part of their workflow, I don't how many there are but its definitely more than one...

Now I can Delete HU for good! I see no reason to keep that clutter-ware on my drive.

I had to look .. this is CS3 .. NOT CS2 so it is a different Raw converter ... it is the same one used in LR so bub by HU ;)

This is an interesting test, though, as others have pointed out, it addresses only one aspect of the image.

The image is almost entirely beige so it is impossible to compare colour rendition. Have you made any tests to compare the converters when given a file containing rich greens, yellows and reds, in various hues?

A nice test might be a bouquet of flowers, containing red and green petals and several kinds of green foliage.

Short comparison of LR and HU based for yellow and green colors. I will also prepare a pciture with yellow, green and red.

LR conversion is the upper image.

As I am not sure whether the JPG link will properly work I also added an additional link.
