The default Lightroom Develop panel settings don’t include an invert tone curve for converting a negative image into a positive, but it is possible to create one of your own. There are several ways you can do this and the method illustrated here in this movie is the simplest you can use to create a custom invert setting.

This tutorial came about in response to a photographer who wanted to photograph negatives with his digital SLR and process them directly in Lightroom. This is the solution I suggested, but as you will see, you do end up in a situation where all your major tone edit controls work in reverse, so you have to use the Blacks slider to control the highlight clipping point and the Exposure slider to set the black clipping point. However, the ability to create this type of setting for use in Lightroom does extend the range of Develop settings and what you can do creatively in Lightroom by applying invert tone curves to produce creative effects such as the Smoke presets creates by Sean McCormack.

A little while back we posted a story linking to an article on the Luminous Landscape website (Do curves throw you a curve?) in which author Mark Segal offered some interesting perspectives on the nature of curve adjustments in Camera Raw and how these compared with traditional RGB composite curve adjustments made in photoshop. In this feature article for Lightroom-News I have concentrated on analyzing the difference between Tone Curve adjustments made in Lightroom and Photoshop curves. I show you here a method for testing curve comparisons between the two programs and some observations on how and why they differ.

The Luminous Landscape website has posted an essay by Mark Segal, who is a member of the Applied Color Theory List (ACTL), on the subject of Adobe Camera Raw (ACR) tone curves. This essay offers a detailed analysis of how the tone curve adjustments that you can apply in Camera Raw or Lightroom compare to the traditional approach of using RGB composite curve adjustments in Photoshop. Over on the ACTL list, Dan Margulis has suggested that it is better to use Camera Raw adjustments to make minor corrections only and use Photoshop Curve adjustments to make the major tone edits. Dan has also argued that in some cases ‘opening the range in Camera Raw actually damaged the image to the point where it was no longer possible to get a good result without excessive effort…’ In response to this claim, Mark has tested his own hypothesis, which is that Camera Raw adjustments applied to a raw capture in Photoshop ACR or Lightroom are not any more destructive than Photoshop and if anything, tone and color edits are easier to make in ACR, but Photoshop edits are still very useful for minor tone and color edits on a rendered raw image.

With the release of Adobe Photoshop Lightroom Beta 4, Adobe has posted a web page for the Lightroom Beta 4 Release Notes. Anybody downloading and using B4 should read the release notes to find out more about new features as well as the known issues.

Adobe has released Adobe Lightroom Beta 4 for Macintosh and Windows, and is available for download at: Labs.Adobe.com. Windows users can now access more of the module features that were previously unavailable in the PC version of public Beta 3. But the main changes in Beta 4 have all taken place in the Library and Develop modules.

In this first part review we are going to concentrate on what’s new in the Develop module. This is the first chance to see how the Raw Shooter raw processing technology has been incorporated into Beta 4, and how Adobe has added more versatility to the tone and color edit controls. Some of the key new features are that you can drag-edit the histogram and have the ability to directly edit the tone curve plus make on-image tone curve edits. Read the rest of this story for an in-depth look at the Beta 4 Develop module.

Photoshop World was last week and it was both a lot of fun and educational for those who attended. This is my report of the first day of my first Photoshop World. I only shot stuff on this first day (I was speaking the other days) so this is the only posting I’ll be doing.

News photographers routinely process images using Adobe Photoshop software. But there has been a basic premise in the world of photojournalism that what was allowed in making prints in the pre-digital days of darkrooms is all that is acceptable today.

George Jardine, Pro Photography Evangelist of Adobe has posted a new iTunes Podcast about Adobe Lightroom with Mark Hamburg (Lightroom founding engineer), Bruce Fraser, Zalman Stern (Camera Raw engineer), and Thomas Knoll, Photoshop co-author and Camera Raw primary engineer.
