CS4 - new and improved features for forensic examiners

You've been asking for the run-down on the new and improved features. Well, we'll take a look at what Adobe is saying and what it means for us.

What they say:
Industry-leading color correction
Enjoy dramatically enhanced color correction with reengineered Dodge, Burn, and Sponge tools that now intelligently preserve color and tone details. Make precise adjustments with Brightness/Contrast and Curves controls, the histogram, color channel lines, and a clipping preview.

What it means for us:
Looks like it's time to redo the lessons again. We used to have to create a gray layer to dodge and burn. We've used the sponge tool for local contrast control. I love what a Curves adjustment layer can do for images. The Histogram tells us a lot about our images.What will the new and improved tools do for us? We'll see in future posts.

What they say:
Improved Count tool
Easily and accurately tally objects or features in scientific images with the Count tool, which eliminates the need to perform manual calculations or rely on visual assessments of changes from image to image. Save even more time by performing multiple counts in a single image. Use separate colors for each count and save your counts in the file.

What it means for us.
Comparisons just got a whole lot easier! Start making plans to revisit Grant's comparison class in Indy.

What they say:
Quantitative data extraction
Easily calibrate or set the scale of an image, including setting measurements to the scale information in the header of DICOM files. Use selection tools to define and calculate distance, perimeter, area, and many other measurements. Record data points in a Measurement Log and then export the data, including histogram data, to a spreadsheet for further quantitative analysis.


What it means for us:
More measuring fun.

What they say:
Scale markers
Easily add scale markers to any image or series of images for presentations or publication.


What it means for us:
Presentations just got a whole lot easier.

What they say:
Edit tracking
Automatically track all editing steps within your files with the Edit History log. Export steps to a text file or save them as part of image metadata for easier documentation of your work, file audits, and more.


What it means for us:
For those of us that turn this feature on (and not everyone does), they've greatly improved the functionality and the relevance of the data that's collected. More good news.

What they say:
MATLAB support
Pass image data directly between Photoshop Extended and MATLAB with the ability to call Photoshop Extended directly from the MATLAB command line. Visualize results of MATLAB algorithms in the software, and combine MATLAB processing with Photoshop Extended image editing to render, test, and refine algorithms for image processing, analysis, and more.

What it means for us:
MATLAB support is huge! I know that we haven't really gone over the benefits of MATLAB here, but we will. How cool is creating your own custom filters and processing tools for those hard to fix images. That's one of the many benefits of MATLAB. In the future, we'll have some examples of custom filters and the code needed to do it yourself. Stay tuned for this one in the early part of next year.

So as you can see from this brief tour, there's a lot to the upgrade ... and this is just the new stuff in Photoshop. I simply can't wait to get my copy.
