Atrise Lutcurve 4

Monitor Calibration Software for Photographers, Videographers and Designers
Lutcurve Screenshot

This program will help you to calibrate your monitor without a hardware calibrator device. High accuracy calibration is achieved by the high sensitivity of the human eye to neutral-color shades. The generated test patterns are based on an scientific article “Measurement of display transfer characteristic (gamma)” by A. Roberts and new extended method for non-linear curves: sRGB, Rec.709 and BT.1886.

As compared to other programs in this class, Lutcurve has high accuracy and flexibility in configuring virtually any monitor. This allows you to get great results even in low-quality TFT LCD displays based on TN-matrix. Best results are on IPS, PVA or OLED. Multiple display configurations or notebook displays are supported.

Users Who Should Use Calibrated Displays

Photo Camera Owner
  • Users working with videos and photos.
  • Designers and artists who work with drawings.
  • Professional photographers and videographers.
  • Software developers and web designers.
  • Just web surfers who love the image quality.

Disadvantages of Non-calibrated Displays

Natural Color
  • Inaccurate reproduction of colors and shades.
  • The loss of image detail in dark and light areas.
  • Incorrect image brightness and gamma.
  • Ugly and unkempt appearance of web pages.
  • Eye strain when working at a computer.

The new version of the program has been significantly redesigned. Most of the code has been rewritten from scratch.
As a result, we got:

Improved Calibration Quality

Lutcurve 4 now supports new calibration standards for photographers, videographers, and colorists.

You can more accurately make color correction and color grading your videos and photos, using the hardware settings of the monitor as much as possible.

The calibration curve is now more accurate by monitoring the area of shadows, lights and smoothness of gradients.

Test images have been improved. The experience of visual calibration using older versions of the program is taken into account.

Modern Calibration Standards

It was possible to expand the visual calibration technique to use non-linear curves used in the new standards.

Now supported:

  • Photo and Internet: Gamma 2.2 and sRGB.
  • Video production: Gamma 2.4, BT.1886 and Rec.709.
  • Support for OLED and high contrast displays.

Settings are now independent for multiple monitors. And accuracy is enhanced by improving calibration images and revised user instructions.

Here is a simple and quick calibration test for most monitors:

your monitor might need to be calibrated!

Note: this simple online test is correct only if you have 100% display DPI settings and no additional browser zoom.
It is safer to check the calibration in the program.

Calibration of Any Display

Atrise Lutcurve lets you correct nonlinearity of displays, especially noticeable on LCD monitors. The count of calibration points is not limited, which means you can calibrate even an aging display.

Calibration Points

The quality of the calibration depends on your carefulness and may be very approximate to hardware calibration results and better.

Ideal Calibration

Multiple Display Support

A multi-display PC installation is also supported on all supported OS including Windows XP.

Two Monitor Support

It is possible to match two display colors.

Multiple Calibration Controls

All values are adjusted by numerical values using the Up / Down button controls. The whole process takes about 15 minutes to complete.

Once the display is calibrated, it takes a bit of time to get over the gee whiz factor that comes from seeing that the images on your display closely match reality.

Technical Specifications for LUT

  • Calibration points: up to 256 (full range).
  • LUT precision: 16 bit (full range).
  • Curve interpolation: smooth spline.

Calibration Specifications

  • Gamma curves and non-linear calibration curves.
  • Recommended gamma value: 2.2. Or use sRGB or BT.1886.
  • White Point: around 6500K.
  • Luminance Level: monitor settings, usually 80 cd/m².
  • Dark Room environment is recommended.
  • Color Space: monitor settings, usually sRGB.

Display Type Compatibility

  • Any CRT or LCD display (TN, *VA or *IPS) is supported.
  • Multiple monitor connected is supported.
  • Windows XP requires separate video cards per monitors.
