Therein lies the explanation as to why your brand new sliders sometimes disappear and the older Lightroom 3 ones reappear – quite simply they do so when you are working on an image processed with an older process version. In short, the Basic panel adjustments in Lightroom 4 so significantly differ to those in Lightroom 3 that they aren’t interchangeable. The sliders in that panel are now called by different names, they have different starting settings and they do different things to those in the earlier Lightroom versions. When Lightroom 4 was released the Develop module’s Basic panel was altered significantly. In most cases, most users will choose to update the process version to the most current one. The options are Process 2003, Process 2010 and Process 2012 (Current).

Here you simply select the desired process version from the Process list.

It’s also possible to update images from the Develop module’s Camera Calibration panel. You can preview the changes before they are applied if desired.

If you want to update an image, click the icon and select to update the image or select to update all the filmstrip photos. If you see an exclamation mark icon in the Develop module to the right of an image this indicates that it has applied to it a process version that isn’t the current version for the version of Lightroom you are using. Images newly imported into Lightroom are processed with Process 2012, and those which were processed in an earlier version of Lightroom remain unchanged.

There is a new process version called Process 2012 in Lightroom 4. Images newly imported into Lightroom 3 were processed using Process 2010.įast forward to Lightroom 4 and the situation is repeated. To have done so might have produced unwanted changes to images which had been already processed so it was left to each user’s discretion to apply the changes or not. This process version had better rendering of the raw image and that meant better detail rendering, better noise reduction and better sharpening.īecause this new Process 2010 was so significantly improved, Adobe didn’t apply it by default to images in Lightroom 3 which had been processed using the older Process 2003. When Lightroom 3 was released it had a new process version called Process 2010.
