Adobe Camera RAW

ACR screen capture 1

Start Adobe Camera RAW and the main Photoshop screen is forced into the background until you close ACR again.

Adobe’s RAW file convertor - supplied with both Photoshop and Photoshop Elements has been updated several times since this review was originally written. However, most of the changes with each new version are to add support for new cameras - The version tested here was 3.4.

When it was first released the interface of ACR was a breath of fresh air, compared to the very clunky manufacturers own products available at the time. However, things have moved on, and although ACR is still very good, it’s interface isn’t the best around any more.

In particular batch processing is awkward and slow compared to either Capture One, RAWshooter or Bibble. ACR floats on top of the main Photoshop screen which is grayed out while ACR is in use. The tabs on the right are well arranged and offer lots of extra functions for noise reduction, correction for vignetting, lens aberrations and colour. By default all the sliders on the main screen are set to auto which I find less than useful - It just never seems to get it right. So I turn them off, but keeping them switched off isn’t as easy as it should be. Next time you load an image they’ll all be back to auto. The trick is to load a raw image then clear all the auto boxes, set the sliders to their mid points then click on the small arrow to the right of top drop down image settings menu, then select save new camera RAW defaults. Once you’ve done that you see the pictures you actually took, not the auto level version. Incidentally this camera raw default setting also determines how the previews are displayed in Adobe Bridge. So if you find, as I do, that your images look nothing like the consistent carefully exposed frames you thought you took, that’s probably why.

Results from ACR with Nikon and Fuji files are excellent but tests I’ve made with Canon CR2 files from the 20D and 5D haven’t been so good. In fact I’ve been surprised at how far behind the results from other software packages Adobe are here. ACR does have some great features though - especially the ease of upsizing images as part of RAW processing. I’ve used this technique a great deal with my Nikon D70 and the results are excellent. ACR also has noise reduction built in but to be honest it’s not nearly as good as that in most other packages. ACDSee’s noise reduction is far better.

It’s hard to criticise anything that’s part of Photoshop but ACR isn’t perfect - especially if you’re a Canon user.
