![]() Having said that, there are many similarly priced models made by Kodak, Canon, and Fuji that produce far more accurate tones with increased vibrancy and aesthetic appeal. Those looking to attain a "realistic" reproduction of the scene, the way it appears to the human eye, will be greatly disappointed however, snapshooters interested in the EX-Z57 as an instrument to merely capture moments in time should not be overly disturbed. While the EX-Z57’s color performance was certainly substandard, the lack of tonal accuracy will not be detrimental to all users. Many of the cooler tones lacked vibrancy, while orange and yellows hues were shifted, resulting in the camera’s 5.83 overall accuracy score. This is particularly noticeable in the under-saturated blue and green channels. Analyzed images were 7.5% over-saturated, which is minimal, but nearly all of the individual hues strayed to some extent from the ideal. The Casio Exilim EX-Z57 scored low on our color tests, earning just a 5.83 overall color score. The greater the distance between the two shapes, the less accurate the camera’s reproduction of that tone. The squares represent the tonal ideal, while the corresponding circles display the camera’s rendering of that particular color. The inner square is camera’s reproduced tone, corrected for luminance.īelow is a more quantitative graph depicting the EX-Z57’s color performance. These tests are designed to indicate the camera’s ability to render accurate tones, as they originally appeared in the scene the score is not a measure of tonal brilliance or vibrancy.īelow is a copy of the color chart modified by Imatest the outer square contains colors produced by the Casio Exilim EX-Z57, while the vertical rectangle is the ideal. Images recorded with the EX-Z57 were shot on a tripod, using the camera’s lowest ISO setting (50) and custom white balance. The results were uploaded into Imatest Imaging Software to analyze the color information and determine the accuracy of each rendered tone. ![]() *To evaluate the color performance of EX-Z57, we captured a sequence of images of an industry standard GretagMacbeth color chart, illuminated by Lowell softbox lamps. ![]()
