Each image's variants are shown in 15 percent increments, but a slider control lets you make modifications. Whereas Test Strip 1.0 displayed its variations in nine sectors of a single image, the new version offers the option of viewing individual thumbnails of the entire image. One Color displays variations of a single primary color. A Flip Layout button lets you rearrange the strips, making it easy to see the effects of color adjustments on different parts of the image. A similar Saturation mode lets you increase or decrease saturation with a slider.
Exposure offers control over brightness and contrast.
