Re: Equalize to recover a sky

Thank you for the reminder and quote. Sometimes Equalize brings out detail, as in the example of the clouds. Sometimes Equalize brightens most of the image without bringing out a noticeable amount of detail. I'm trying to relate the histogram-leveling Equalize operation and the change it produces to...

Equalize to recover a sky

The top image came out of a raw converter. I reduced exposure in the converter to avoid blowing much of the sky, but it has a dull uniform overcast. Stumbled on the idea of applying Special Effects | EqualizeHSV through a mask of the sky. The bottom image is the result - amazing recovery of clouds. ...

Soft light with itself

A start that solves the bulk of the problem is: Composite | Soft light using the original image as the overlay image, too.

Re: Soft Light blend mode

Perhaps this recipe does something like to goal of the original post:
  • FullRange-HSL (might leave image badly desaturated; don't worry)
  • make a mask by brightness, inverse diagonal
  • Composite | Soft light through mask, amount to taste around 50%
  • compensating contrast with a Brightness-RGB S-curve

Re: What does No WB mean in the Raw dialog?

Thank you, Kiril. Yes, the occasions to select No WB are rare. (Odd reversal here concerning who deprecates a PWP option.) Occasionally, No WB is the easiest start when you want to keep a desired color cast, like a late afternoon "golden hour." Also, when you have a shot of a scene and ano...

What does No WB mean in the Raw dialog?

One of the options in the Color tab of the Raw dialog of Picture Window Pro is No White Balance. Is that literally true? Or does it mean a kind of standard white balance, applying a fixed triple of ratios to the (R, G, B) values or a standard temp and tint like 6500K and 1.0? The answer will presuma...

Re: Rotating A Picture In Three Dimensions

The sample image shows a fairly flat scene, so it minimizes the problem with 3-D rotation: such rotation brings new things into view, but the camera did not capture pixels for them. Imagine a photo showing the earth from a camera in a fairly low orbit satellite over Chicago, Illinois. Now rotate so ...

Another method using Equalize

Another method: Look at Special Effects | Equalize, examining both HSV and HSL and make a choice. Sometimes the amount slider will find a suitable result. When it does not, Composite | Soft Light the original as the base image and the equalized image as the overlay, adjusting the amount slider of th...

Printing and the HSV versus HSL histograms

This problem image has a dramatic disparity between its HSV and HSL range of values. It printed with much weaker colors than seen on the monitor. http://www.flickr.com/photos/41790885@N08/5858286412/sizes/l/in/photostream/ For comparison this image printed close to what is seen on the monitor. Same ...
