Welcome to Curvemeister!

Curvemeister is constantly adding new features. If you have not upgraded, it's free to owners of Curvemeister, so now is the time! The information here will be interesting if you are already familiar with Curvemeister. If you are just starting out, you may want to skip ahead to the Getting Started section.


v2.4.3

  • Fixed a bug that caused a crash if both histograms and the master curve were enable.

v2.4.2

v2.4.1

  • Added floating color pins. You may now"float" a Hue/Sat pin by dragging one of the curve control points.
  • Fixed a problem with sample palettes sometimes extending past the right edge of the image preview window. The palettes now re-locate themselves correctly.
  • Changed curve drag behavior to prevent removing a curve control point that was created by a pin. You must now delete the pin to remove its control points.

v2.4.0

  • Fixed a problem with pin grid distorting the lower left half of the curve when grid squares = 9.
  • Added an option to support soft proofing.
  • Improved the user interface of the saturation slider.
  • Removed the minimize and maximize buttons from the Curve Window.
  • Use Photoshop's checkerboard transparency display to display transparent areas.
  • Save the location of the sample palette windows.
  • Keep separate track of folders for saving and loading curve files, sample files, and pin files.
  • Fixed a problem with changing Pin mode from "hue/sat" to "neutral".
  • Added support for threshold highlighting when moving thresholds in wgCYMK and CMYK mode.
  • Add support for CurveGuard when using the arrow keys
  • Fixed a problem that prevented scrolling of certain images, such as panoramas, from being viewed and scrolled to in Curvemeister

v2.3.0b

  • This version fixes the version number of the installed plugin. v2.3 incorrectly had a version of 2.2 There are no other feature changes.

v2.3

  • Fixed a problem with new shadow and highlight values requiring a Curvemeister restart. Retain user name from previous install, instead of always using the name the very first install.

v2.2.0b

  • This version includes several installer changes. There are no functional changes to Curvemeister.
  • The installer is distributed as a .exe file instead of a .zip file. This change was made to simplify the installation procedure.
  • Some pin values have been replaced with more accurate values.
  • A problem that sometimes required re-entry of the user name during installation has been fixed.
  • Minor changes to the manual.

v2.2.0

v2.1.15

  • The installer correctly defaults to the latest version of Elements for systems with more than one version installed.
  • The installer correctly identifies the plugin folder for all non English systems.
  • Fixed a bug introduced in v2.1.13 that prevented dragging a curve control point all the way to the edge in some situations.

v2.1.14

  • Fixed a bug that prevented pasted text from being intrepreted correctly in situations where an external editor has added blanks to null lines.

v2.1.13

  • Arrow keys now move samples by one image pixel, arrow with shift moves 10 pixels.
  • Improved the prioritizing of pins. Clicking on a pin or a neutral gives it the highest priority. For example, in Lab mode, the last clicked neutral takes priority, instead of the first one created.
  • Changes to the curve interface, including reduced flickering during redraw, and the ability to reliably click on a point to select it without moving it.
  • Eyedropper commands are handled more consistently. A menu command will affect all of the currently selected eyedroppers, instead of the eyedropper being clicked on.
  • Compare mode includes image data from other layers.

v2.1.11

  • Altering a pinned sample using the picker now correctly updates the curve.
  • Further improved the rotation function for individual curves.

v2.1.9

  • Fixed a bug that prevented numeric entry of saturation slider slope value.

v2.1.8

  • More improvements to saturation slider, including a numeric readout and spinner.
  • Support rotation of individual curves via a click and drag that starts in the margin.

v2.1.7

  • Saturation slider. This is an experimental slider to control saturation in Lab mode. To activate it, press Shift while clicking in the Lab radio button.
  • Compositing during compare mode. Curvemeister correctly displays underlying layers in compare mode. Overlying layers are still not displayed.
  • Deleting curve points. The delete key deletes the currently selected curve control point.
  • Several improvements were made to the selection of sample points.

v2.1.6

  • Fixed a window centering problem that could cause bad initial locations for the curve file Load and Save dialogs under Windows 2000. Curvemeister now initially centers File dialogs on the desktop, and retains the user selected size and postion for the remainder of the Photoshop session.

v2.1.5

This is a fix release that affects all owners of the product. This version contains bug fixes, additional pins, improvements to the appearance of the threshold image, and more.

v2.1

We've added quite a number of new features to version 2.1. As always, these features are free if you own Curvemeister 2!

Note: If you are using version 2.0.21 or earlier, be sure to upgrade and see all the new stuff we've added. If you are using the demo, you may upgrade via the web, otherwise use the Start button to access the Curvemeister update command.

Here at the Curvemeister Institute, our designers and technicians have been busy adding new features to Curvemeister. These features are centered on adding functionality to pinning, and to the Hue Clock and the accompanying numeric displays.

If you're already up to speed on Curvemeister 2.0, here's a brief description of what has changed in the last release. Look for the links within each description. These will take you to the relevant manual page for more detail on a particular feature.

Commands for changing pins are accessed by right clicking on this window

  • Pin Tabs - groups of pins may be organized into sections, and accessed by clicking on the corresponding tab in the Pin Palette.
  • Pin Files - you may save individual sets of pins as separate files, and load them manually when needed
  • Pin Management - you may create new pin files, edit individual files, and organize them using menu items from the Pin Palette. To install a pin file, so that it loads by default, move it to the Swatches folder.
  • Experimental pins - various pin files are located in the Goodies folder. Use the Open Pin File command in the Pin File submenu, accessed by right-clicking on the pin palette window. This accesses the goodies folder containing the experimental pins.

Version 2.0

If you are just upgrading from Curvemeister 1, the big features for version 2.0 are Color Pinning, and the Hue Clock. Add to these major features a wide array of supporting features and enhancements and you have more leverage than ever to make good looking images, and to do so in absolutely the coolest way possible.

Let's get started with the introductions.

The Pin Palette

Pins provide a new and powerful technique to retain and apply knowledge about specific colors to your images. Getting a good flesh tone can be as simple as dragging a flesh colored pin onto your image, admiring the resulting curves, picking the color space that looks best, and clicking OK.

What do you do when the most important color in the image is a flesh tone, you've jumped through all the hoops you can find, and it somehow just doesn't look right? Enter color Pinning, a method for selecting a color from a library of target colors and applying it to your image.

Curvemeister provides you with an expandable and easy to use library of target colors. Just grab a pin from the Pin Palette, drag and drop it onto your image, and use the resulting curves for the remainder of your curving. Pins are organized as text files that you may edit in the usual way and easily share with others.

The Pin Palette also supports a number of advanced features for the professional, including configurable CMYK shadow and highlight values.

The Hue Clock


See how what your colors are doing as never before!

Until now, Photoshop folks have had two ways to determine the relationships between colors: looking at the image and looking at the numbers. Now there's a third:: the Hue Clock, which displays hue and saturation as a quick, easy to read clock dial. Using the Hue Clock, it's easy to determine, effortlessly, whether a flesh tone is reasonably accurate (12:30 on the Hue Clock), sweep the cursor over and image and get a good sense of color variation. The length of the hand indicates saturation.

Floating Neutrals, Copy and Paste, and More

Imagine in your minds eye, that you are moving the green point
up and down and the red and blue points are following right along.

Let's start with floating neutrals. This feature allows you to use a neutral as a "handle" to change all three of the RGB curves at the same time, while maintaining one or more neutrals. Set your neutrals (or pin a color), then move one of the RGB curves vertically to adjust overall brightness and maintain your desired hue and saturation values. This is a "floating neutral" and it provides an alternative to RGB or Lightness channels, because you can modify the overall brightness of the image with less chance of causing a color cast..

A similar operation works, with some additional care, for pinned colors as well, so you can pin a flesh tone, and move one curve vertically while keeping your pinned color where it belongs.


Is copied as:


wgCMYK: (0,0) (65,50) (100,100)
Cyan: (0,0) (25,39) (61,53) (100,100)
Magenta: (0,0) (100,100)
Yellow: (0,0) (100,100)
Black: (0,0) (100,100)

Copy and paste. Most of us would scream if copy and paste were removed from our favorite text editor. Likewise, we will breath a sigh of relief when copy and paste makes its arrival in the world of curves and colors. This feature saves you a lot of time if, for example, you've spent several minutes tuning up the perfect Lightness curve, and want to take it out for a spin on the RGB curve. This is easier than ever because there is no need to recreate all that effort - just copy and paste, and you're on the air with your curve in RGB instead of Lightness. Use this feature to quickly copy the same curve in multiple channels, or to use on multiple images.

Ever want to email someone a description of a color or a curve? Now you can copy and paste a curve in text form, suitable for pasting into a reference document, or emailing to a friend.
