The only times I've re-opened an image in ACR after initially processing the image in ACR is as a tiff on the rare occasion that I do an HDR image. Then, it's only been as an experiment to make sure the process I use works. Otherwise, it's a rarity that I ever need to use HDR.

The adjustment brush is absolutely amazing. Not only can you control the flow for cumulative adjustments, you can vary the adjustment parameters after the fact.

As ACR is in CS6, the answer must be none.

However, suppose you have a pale blue sky and want to increase its colour strength without affecting other parts of the image:

in CS6, you could burn the sky using a soft brush, you could select the sky and change the hue/saturation, you could colour select, make a new layer and work the magic that way. Probably half a dozen more ways to achieve the same thing.

My own preference is to pop into ACR, choose the brush, paint over the sky with the mask selected which prevents the clouds being painted, adjust exposure / saturation etc. then click done. Open or save image.

The brush in ACR is a very flexible tool, it can be "loaded" with 11 adjustments all at the same time including colour change. I would normally only load one or two adjustments at a time, but this is a flexible beast.

The brush is really easy to use to be rid of any artefacts created in the HDR process, a lot easier than cloning etc in the non ACR part of CS6.

I will not bore you by extolling the virtues and usefulness of the graduated and radial filters over those of the grad. filters outside of ACR, nor will I speak at length of the improvements made to those filters in ACR in CC, but it all boils down to how you like to work.

What's really weird for me is that I have it set up the way you described and the tiffs still open in CS6 and only occasionally will the tiffs open in Camera Raw!

Anyone know why?

Q: Are the tiffs that do not open in ACR - layered?

Davet Loc: Fort Myers, Florida

After I do the HDR thing and select it in a TIFF format I cannot open it in RAW. I want to for picture refinement.

Wendy2 Loc: California

I never really noticed but that may be the answer. I will experiment. I save the tiffs with layers just in case I need to go back and tweak them.

I just flattened a tiff image, re-saved it in tiff and it still opens in CS6 instead of ACR hmmmmmm......

Searcher Loc: Kent, England

Just double checking:

You have saved the Tiff to disc
You open CS and choose "Open As"
You navigate to the image, and select it
You Change the selector (for want of a better word) to Camera Raw
You choose OK or Open

I can't do a screen shot of CS6 but it probably looks much the same as CC. In this I am opening a jpg into ACR

Did that. Only opens my tiffs in ACR now and then, hit or miss. 99% of the time does not.

I am at a loss, I followed my own instructions with PSE9,11,12, CS2, PSCC and PSCC2014.

They all work properly except for CS2 which could not "Parse the file." The tiff image refused to open in any part of CS2, but did in all the other applications, both ACR and the main programs.

Thanks for trying to help solve this problem!! It is not a huge problem, but sometimes I want to open tiffs in ACR.

I use smart objects and as long as I don't flatten or merge the layers and don't make copies of the background I can open the tiffs and then click on the smart object and it will then open in ACR.

Thats a neat trick, hope the OP is still reading - it might work for him.
