Do you adjust levels twice?

When converting from RAW, do you adjust your levels in ACR and then with the Levels tool
in Photoshop, or do you only use ACR? I used to only use ACR but now I feel that I can get a
finer grain of control by using both -- just curious what others do.

It's an old person's underpants, really.....

Should be lots of info here:

If not, then perhaps you can post a thread there (it's the appropriate forum for such issues)

I'm moving this to "RAW, Post Processing and Printing".

To answer the question, I do, sorta', because I use the masks in Adjustment Layers to make changes to only part of an image:
A small tutorial - Adjustment Layer Masks

Generally I just make the adjustment in ACR....sometimes I may make another in PS if the photo requires more work.

There are good reasons for making the maximum use of your Raw files and Raw processors for substantial work with colors/tones -- this is really what Raw is "designed" to do!

That being said, a lot is up to the individual and your preferred workflow. A lot of us rarely go into the Photoshop editor at all, and then only for "special" tasks that a Raw converter can't touch, and even that has changed, with the local adjustment brushes and such that we find in ACR/Lightroom.

But others are practiced and happy with Photoshop being part of their ordinary workflow, and for their work, well, you choose what works for you!

100% ACR. ACR has the most data, and the best controls IMHO, do anything and everything you can in your raw converter.

You asked about ACR and my answer is about LR, but I will post it anyways because other LR users may find it useful. This is one of the few areas that LR differs ACR. The ACR histogram is predictive of the rendered RGB image in the output space selected but until now the LR histogram has portrayed a theoretical output that has no reality - a space with ProPhoto RGB primaries and the sRGB tone curve (roughly gamma 2.2 but not exactly, ProPhoto RGB has a gamma 1.8 curve). Because of the possibility of gamut clipping (clipping caused by going from a wide gamut to a narrow one) with critical work to be exported in sRGB from LR3, I leave a bit of headroom above the white point and tweak it after export. However, since the appearance of LR4 with soft-proofing I can see the histogram and the visual preview in any space and the additional adjustment is no longer needed.

So tzalman, I'm new to LR and downloaded the beta. I use sRGB color space in photoshop. It sounds like I should always have the softproofing turned on and select sRGB in LR4, at least if I plan on doing more editing in photoshop.

The truth is that the soft-proofing is still a little buggy and there may be some changes made, but the way it works a present is that if you turn it on and then move a slider it asks if you want to make a virtual proof copy and you can then edit that until your "sRGB version" looks the way you want it.

I use photoshop Elements, and that ACR engine does not have a Levels tab, so I an forced to do in Photoshop, hence, I only do it One Time
