New tools in ACR 4.1 - DPChallenge Forums

I thought this made for a very good read of the new tools found in Adobe Camera Raw 4.1 (ACR).

For those of you sitting on the fence, it's all the more reason to switch to shooting raw! (note: the same update in tools found in ACR will be in the next update for Lightoom, so you can start playing with and getting used to the tools now)

Sharpening halo removal. DPC images all just went +1!

Yeah. Funny thing is it's not hard to remove at all with the clone tool. Just set it to darken blending to remove white halos and lighten blending to remove dark halos.

Btw, I would assume using the sharpen halo removal feature in ACR would be illegal in basic.

The writeup makes it sound as if the actualy sharpening process removes the halos, or prevents them, as it goes. Challenges aside, can't wait to check it out.

I'm not sure how that will be detected and enforced ... unless the .XMP file is now required for submission as part of the proof.

With so many advancements coming in the raw conversion tools, the world of basic vs advanced editing could get really complicated.

ok, just installed and played with it a bit, and it definately adds to ACR and gives even more ability to edit the raw before going into PS. Now they just need to update LR so I we can batch edit needed files.

Why wouldn't it be enforcable? The photographer is suppose to list their editing steps. Even if they omitted that step I'd imagine the SCs could still DQ it if they can't replicate the sharpening without the halos forming.

On the other hand, why should halo-less sharpening be against basic rules?

If you're thinking it's because it's doing under-the-covers masking, well, then what about the Shadow/Highlights adjustment? It also does masking under the covers.

Well apparently there is no under the covers masking with this sharpening tool it even has a slider called masking. Looks like you can select just the edges with that which seems very much against the rules. Maybe everything up to that point would be fine since it just effects the luminosity and not a specific section of the photo. That's similar to how the shadow/Highlights Adjustment works that is it effects the entire image's tonal range and not a specific area of the photo. Tonal and color changes are always fine it's when it's applied selectively that runs into a problem in basic. Anyway, this is just my interpretation of the rules. For all I know the SCs will all welcome this tool with open arms. :P

Btw, will this update only work if you have Photoshop CS3? Would I be able to upgrade my ACR that came with CS2?

From what I understand, no... Which is an interesting concept. That means that if you purchased a new camera which wasn't supported by the previous ACR, then your only recourse is to upgrade to CS3 first, before you can upgrade to the latest ACR. Kinda sucks if you hadn't planned on spending the $$$ to upgrade to CS3. However, CS3 really is a nice upgrade from CS2 (much mores than CS2 was from CS).

Yep, crap:

The Camera Raw 4.1 plug-in is not compatible with versions of Photoshop earlier than Photoshop CS3

I like the new b/w conversion (maybe it was there in ACR 4.0?) is it basic legal?

I never liked ACR 4.0 (and still prefer Lightroom over Bridge+ACR4.1), so I don't know the answer. But I do know that LR has the b&w conversion you are seeing and I agree, it is sweet! I'm not even a big b&w fan, but this feature in LR (and now ACR 4.1) makes it easy to get great results!

I'd imagine it would be legal in basic as it's not much different than from using some of the other controls in PhotoShop. The main difference I see is in the finer-grained control over which hues are being adjusted.

Here's something I popped today. Was thru glass at the Camden Aquarium so thats why light is so bad in original.

All adjustments in ACR4.1 - Didn't even use the sharpeness features. Even the older controls seemed to work better.
