Little Argyll GUI vs QuickGamma

Little Argyll GUI is an open-source graphical front end for the ArgyllCMS color-management system. Its controls help create and use ArgyllCMS commands for display and printer calibration and profiling, as well as camera and scanner profiling. Saved parameter sets support repeated work. The program can create daylight-series spectrum files with selectable ultraviolet filtering and custom patch sets for grays, near-grays, or tones such as sepia; printer patch sets can include those additions. Documentation links appear throughout the interface. Version 1.0.1 is a Python 3 script with a GTK 3 interface built using PyGObject, and updates Argyll 3.0.0; some parameters are absent in older Argyll versions. Linux, macOS, and Windows instructions are provided. Windows setup uses MSYS2, while macOS setup uses Homebrew. On the maker’s Windows 10 MinGW-w64 system, the background selector does not work. Use requires a color measurement device, such as an i1 Pro 3 or ColorChecker Studio. The listed price is $5 as a one-time purchase payment.

QuickGamma is a Windows utility for adjusting monitor gamma without expensive calibration hardware. It can correct gamma to 2.2 and create an ICC profile with a VCGT tag containing data used to load a graphics card’s lookup table (LUT). QuickProfileLoader is installed automatically with the utility and can load a monitor’s LUT from that profile data. The listed capabilities also include LUT calibration, ICC profile export and multi-monitor calibration. Version 4.1.0.0 requires Windows 10 or higher; its installation file includes 32-bit and 64-bit versions, help files and no runtime libraries. QuickGamma is free for personal use, while commercial use requires written consent from the author. Private users may distribute the complete, unaltered installer, but not individual components. The author offers no express or implied warranties and invites donations. A SHA-512 checksum is published for checking downloaded file integrity. The maker also lists utilities for reading LUT and VCGT data and creating monitor ICC profiles.
