LR is just further ahead in the development curve. ACR will catch up, and to be fair to Adobe they are generally ahead of the game compared with other 3rd party developers.

Just a temporary work-around.- EdM.Ed dont get me wrong when I state the case below. DNG has uses but only as you say a temporary stop gap not as an alternative to keeping RAW files. DNG is a horrible hook, no wonder Adobe gives it away free. They market it as a one size fits all concept and the fact that it is free. But a DNG is really just a RAW file converter that makes a DNG (just like ACR can make another format from a RAW image). A DNG is actually a type of TIFF, called a DNG. The concept of something for nothing is there. We all know in this life there are no free lunches. The Case for DNG. 1. If you have a DNG then you can use Adobe DNG processor to produce a JPG or TIFF. 2. The same DNG processing software is used for all DNGs. 3. DNGs are smaller than RAW so are easier to store. The Case against DNG. 1. The making of a DNG requires each RAW file format to be a known entity so it is as complex to make a good RAW==>DNG converter as making a RAW file converter. 2. Adobe say the process is lossless. If it is lossless what are they throwing away to make the file smaller ? Dont trust them to make these decisions about your images. Basic principles apply, you cant make something smaller without losing something. (JPG is lossless if you dont count the stuff you lose in compressing it). 3. If the DNG converter doesnt know about your RAW file it cant make a DNG. The DNG processor is used to make a TIFF or JPG only. You still edit in other software. 4. If it is so good then why are they giving it away ?  Cant believe that Adobe are now a not-for-profit organisation.5. If you throw away the gold standard (e.g. RAW file) then you just have paper promissory notes (like now!!) (e.g. DNG file) and look at the economic mess we are in because not all bankers are trustworthy. 6. The current DNG processor runs on Intel technology. It we suddenly move to HiLo processors (a fictional name) then there is no guarantee that the old DNG executable will run or that Adobe will recreate the DNG processor to support all the legacy cameras and their DNG formats in the new version that runs on these new processors. I think that there is a case for stop gap measures but I'd really be extremely reluctant to not try and stop someone converting their RAW files to DNG and throwing away the RAW files. And Yes I have heard people of doing this as they sincerely believed the Adobe DNG speak!

I don't use it either JK, but in a pinch situation it is a fall-back alternative. If I had a D4, took a series of shots that I needed to process for a client (which I also don't have) and couldn't get PSCS 5 to decode the NEF's, but could do it in LR4, I'd strive to get the job done first, then worry about an ACR update later. Of course I would keep the raw NEF's on my CF cards, or whatever, or transfer them to a hard drive with a simple program like 'Nikon Transfer.' I honestly didn't mean to start a discussion over the merits of NEF vs DNG, which I believe has been argued at lenght in the old forum. - EdM P.S., If PSCS 6 is released prior to the ACR update, those of us with PSCS 5 may still not get ACR for either the D4 or a new D400, if Adobe does what it did in the past and stop updates for its older versions.

I certainly hope that Adobe release ACR 6.7 soon as I dont want to have to rely on upgrading to CS6 to get something to process D800 NEFs In fact I wouldnt anyway as I have D4 and D800 support in AfterShot Pro.

You don't need to convert the image to DNG in Lightroom to use it's ACR engine on a Nef. Just select the image and right or control click and choose edit in Photoshop. It will then tell you that the photoshop ACR is an older version and give you the option to render in Lightroom. As I alway browse my photos in Lightroom and then open into Photoshop from here for me this is no extra work at all, and you don't need to go near DNG to do it.

Havent done that Rich. Looks like I need to test that out. Might be good to do a mini-tutorial and post it into the subforum that is still empty waiting for these sorts of items.

Will do, I'm off work still as contagious, so I'll give it a go tomorrow. Downloaded CS6 as well, so I'll do a quick write up on that.

If you have Lightroom (and use it fully to import and do the basic editing) I don't know why you'd ever bother to pass through ACR on the way to photoshop since you can't save a raw after you reach photoshop anyway Btw. Lightroom rather nicely allows you to roundtrip any images that you open and save in photoshop (or other software)
