If you upgraded to Lightroom 4 and imported some new images, you might be a bit perplexed with the Develop module’s Basic controls. Fill Light, Recovery, and the Brightness sliders are gone.
Here is an explanation in the Lightroom Journal: http://adobe.ly/wMpLrU

The Lightroom Queen, Victoria Bampton, provides a quick insight in how to think about these new controls:

By the way, if your question is: Where are these new controls? They are right there in the Basic panel, but you need to convert your image to Process Version 2012. Click the ! icon in the lower right of the image area. Julieanne discuss this in her video.

A better question is: “Where did manual Chromatic Aberration correction go?”
Using the automated profiles for this don’t really work correctly in all conditions, such as when certain filters are attached to a lens (these can add or change the degree of aberration too)
Good question. The manual sliders are gone and chromatic aberration correction was removed from the automated profiles. To manually apply correction, click the Remove Chromatic Aberration checkbox on the Lens Correction’s Profile tab. It may seem like you have less control with the old manual slider gone, but you should see better results.
