Thanks for the article. I am using this technique on copystand work where I need an even paper white despite small differences in lighting and incidental sensor marks. A blank sheet of paper of the same type as the art being captured is imaged first, then the art is captured. The two images are then blended using the technique you describe. Divide is a very nice addition to the blend toolkit and I appreciate your article pointing it out.

I am not so familiar with Capture One of Phocus, but if the raw processing software allows you to calibrate at the post-capture stage, that would be better than using Photoshop surely? By lens casts do you mean that certain lenses affect the overall white balance? I have seen this with other systems where different lenses can affect the colour. Surely, it is easy enough to use a white balance card to check the white point, or even carry out a fuller camera calibration which is really easy to do now with the Adobe DNG Profile editor.

I always take a second picture (+1 EVstop) with an opaque filter on the lens. You then have to calibrate everything in Capture One or Phocus (Hasselblad) software, but it would be nice if this was possible in PS.

Hopefully it’s not a ‘back-breaking’ stunt to master them!

Content-Aware is a powerful new feature, but as Chris pointed out, doesn’t necessarily apply well for automated tasks. I have come up with some scenarios where the Content-Aware fill feature could be used to automate cleaning up an image, but the examples I have thought of so far are rather image-specific. One could make a great tutorial based around this, but it wouldn’t truthfully be that applicable to everyday retouching jobs.

Dah! Of course CAF will not do the same. I think I got played out because of the simply blue background for the demo spots. I guess we call those a senior moment :>)

Thanks for the correction and sorry for the bother..

Best…Michael

Dividing by the white field brightens what was underneath, preserving the details.
And are you going to CAF out vignetting or large smudges?

While Martin showed small dirt, divide is useful for restoring any sort of darkening due to lens/sensor artifacts.

Thanks for the tip on this obscure feature. My question is…why not use content-aware fill to get rid of sensor marks? You could store the selection(s) of where the marks are and then apply CAFill which should take care of any photo shot with the same dirty sensor. Of course the vignette would have to be handled separately.

Best…

Michael

Now that Adobe have announced CS5 products, the actual release date of the program is not far off and all publishers should be allowed to start advertising their books. It usually takes a little while for Amazon and other on-line stores to get submitted books appearing on their sites, so I would suggest keep checking from time to time. All I can say is that my books are usually out within a week or two of the program release date and I don’t see this edition being any different.

Regards Photokit products, Pixel Genius have to make sure that their products are compatible with subsequent versions of Photoshop and latest operating systems. All I can say here is to look for an announcement around the time CS5 ships.

And it can correct for other defects that ACR and Lens Correction can’t do yet.
But mostly divide is a building block blend mode for calibrated imaging and compositing (and some people have come up with more creative uses already).

Amazon doesn’t yet project a shipping date. I’ll be making the jump from CS3 to CS5- any wisdom about making that leap?
And lastly, will my Photokit Sharpener (an absolutely essential plug-in) play nice with CS5?
Regards, and thanks for all your good work,
Jed
