Lightroom 2.0 and ACR 4.5 « Thread Started on Jul 29, 2008, 10:15pm »
Just thought I would pass on to those who use these products and to those who might want to, that Lightroom 2.0 and ACR 4.5 for CS3 are available to download from the Adobe site. I had been using LR 1.0 since it was a Beta and had downloaded 2.0 as a beta also and have found there are some neat things in LR 2.0. For Canon users you can also download picture styles for use in LR 2.0 (from the Adobe site) and ACR 4.5 has them included. I found that ACR 4.5 has added a bit of snap to images for some reason and this even shows on images from my wife's Canon SD870. Maybe it's just me again. I really got into LR through having Raw Shooter Pro. Adobe bought the little software company Pixmantic, and gave everyone who had RSP a free version of LR 1.0 if they wanted it. It takes a little time figuring all the LR features but it is well worth it. Best engine for printing, making pdf slide showsand web presentations I've seen. Plus a very good DAM for storing your images.

I've been using the Lightroom 2 beta since it came out. I'm loving the support for dual monitors! The fact that it does not honour custom white balance still annoys me greatly, but for regular images I can't fault it!

It's worth noting that with the release of these two that Adobe have also released a DNG Profile Editor. This allows you to create a custom camera profile which doesn't clip the custom WB.
Convert at least one IR image to DNG format with the free DNG converter, downloadable from: http://www.adobe.com/products/dng/ (or import into Lightroom as DNG).
When you've saved your new profile, close and restart Photoshop/Lightroom and select the new profile under the 'Camera Calibration' tab.
Unfortunately, at present there's no way to have Lightroom apply this profile automatically to your specific IR camera - it can only do it to all images, or none. I have saved a develop preset which applies the profile change at a click of the button, but this must be done every time you bring in new IR images.
It's also worth noting that you only need to convert one image to DNG - once the profile is created, it can be used on any RAW file, DNG or otherwise.
Hope this helps. Finally I can edit my IR images with the same workflow I use for my visible light stuff.

Just to show what I'm talking about a bit:
Here's a bit of the Lightroom display, showing the neutral colour balance of the image, with the WB set to 'As shot'. This was after the calibration profile was set to my custom built one:
The temperature and tint numbers are a bit extreme - I suppose the ideal would be for daylight-shot IR images to have the numbers somewhere in the middle. This can be done by fiddling around with the profile editor to find the best balance.

Peter I tried one using my mkIIn and its pretty nice. Will have to do the 20D and see if perhaps this may be a way to store differing WB for IR, it might well be but have to think more on that. Previous for my other cameras I had made a few Presets and made one for my Sigma DP1 converted tiff files since there is a hold up for ACR support on Sigma's end. This new method does allow for more fine tuning of the RAW files then making just a Preset.

Hi folks - Glad you found this useful. I have since discovered how to make the new profile the default for a specific camera:
In Lightroom, go to Preferences->Presets and check the 'Make defaults specific to camera serial number' option, then on an IR image, set the calibration profile to your custom one. Hold down alt, and the 'reset' button at the bottom of the screen will change to 'set defaut...'. Click that and Bob's your uncle. This will now be the default profile for both Lightroom and Camera Raw.
You can get to the same thing in Bridge by going to Camera Raw Preferences.
