Abstract

Accurate Color Reproduction is very important for Cultural Heritage purposes, mainly for documentation. Normally the digital images are more saturated and contrasted than the human eye can see it and became necessary to recover the right color information. This research will present the color difference, in terms of CIELAB ΔEab* , by four different smartphones with Auto Settings, with and without neutral color on the image provided by color targets (Colorchecker passport and Kodak Q-13 grayscale). To verify the color accuracy, some color samples were produced by a professional print and fineart paper. The colors printed were: Red, Green, Blue, Cyan, Magenta and Yellow. To perform the color analysis and color correction were used four methods: image without color target, with color target, linearization by Colorchecker (greyscale patches) and Color Profile. The result shows the accuracy in terms of color reproduction, the best, the worst and the average for each smartphone for all six printed color, as well as the best methodology for each smartphone.
