ColorAssist 对比 Depth of Field Calculator 的使用情况和统计数据

Use the camera to capture RGB values in real-time and convert them to the closest color name from a dictionary of nearly 900 colors. Also available: RYB, HSL and CMYK values, HTML color code, closest HTML color name, and simple color name. Touch a color square to view the information for that sample at any time. "Auto" uses the camera's auto focus and auto contrast adjustment feature. "Lock" fixes or locks the current contrast setting. And "Target" allows you to touch any area of the screen to select that spot as the source for the color sample (in cases where moving the device would disrupt the focus/contrast, or where the device is mounted in a fixed position). Manage named color sample sets on the Edit screen. After organizing a sample set, email the color samples with color chips, with color chips and a selected photo, or as text only. On the Options screen, select which color conversions to display, and set the spacial and temporal apertures from 1x1 to 50x50 pixels, and 1 to 30 frames. Touch the "Target" selector then touch the screen to move the sample location without moving the device. App Store screen shots simulated Photo copyright E.

Depth of Field Calculator

Calculate hyperfocal, near, and far distances, as well as Depth of Field values. How to use: 1. Select your camera sensor type or size. 2. Input the aperture, lens focal length, and focus distance. Outputs: - Hyperfocal Distance: The closest distance at which a lens can be focused while keeping objects at infinity acceptably sharp. - Nearest Limit and Furthest Limit: The range within which objects stay sharp. - Depth of Field (DOF): The distance over which objects appear sharp. Explanation: Depth of Field (DOF) is the range of distance in a photo that appears to be in sharp focus. Depth of field is a creative decision and one of your most important choices when composing nature photographs or films. This tool is invaluable for assessing the camera settings required to achieve the desired level of sharpness. Thank you for your support. Visit nitrio.com for more apps for your iOS devices.
