With the problems and quirkiness of the SD14, I was not recommending that camera without some real reservations. It's a surprisingly compelling upgrade, and would be a great entry camera for someone looking to discover Foveon images. ![]() Especially given that there's a new shutter in there (my SD14 was replaced because of shutter issues). I was of the opinion before I shot the SD15, that it was just a modest upgrade and not worth the price of admission. With regular mode, it's not a lot better.īattery life: Yes, yes, yes!! I routinely get 800-900 shots of out a battery now. To me, it looks the same.īetter AF: Yes, especially with continuous mode (tracking). I won't necessarily say 'better', but easier to get to.ĭynamic range: No. Not as dramatic as the speed, but it's definitely better in the shadows than my SD14.īetter colors: Yes. A device noise profile describes the properties of noise produced by an imaging device (e. g.In replying late to this, the "SD14 owners need not upgrade" may be moot (thank the SD1), but let me go over some of my findings after using this camera for a couple months. digital camera, scanner, etc.) working in a certain mode. Specific flat featureless (noise-only) image areas are used to build such profiles. The new Sigma has improved noise and bloom control for cleaner, smoother images with better controlled color saturation and detail. You can also select such an area manually.Ĭlick the Auto Profile button to automatically find and analyze a flat featureless area in the input image Examples of image areas that can and cannot be used to build a profile are located at the bottom of this page.Īuto Profile function in Neat Image can automatically find flat featureless areas if such areas exist in the input image.

If an image does not contain such featureless areas, you can use either another image from the same series or the Calibration Target to build a new noise profile for the input image. #SIGMA SD14 NEAT IMAGE NOISE PROFILES SERIES# The Calibration Target is specifically designed to easily build reusable profiles for various imaging devices. It can be used to build a single profile for a certain device mode or a set of profiles for different modes.Īn imaging device can work in several different modes. Preparing a set of profiles for different device modes enables accurate processing of arbitrary images produced by this device. Such profiles better reflect the specifics of the camera or scanner as well as the workflow you use. To learn how to plan, build and structure a set of profiles please refer to User Guide (section "Preparing profile set for different device modes"). ![]() #SIGMA SD14 NEAT IMAGE NOISE PROFILES HOW TO# The user guide can be opened from the main Neat Image window by pressing F1 or downloaded separately.

Once you build a set of noise profiles for a specific device yourself or download a ready profile set for your camera or scanner from the profile library, you can use the the Auto Match function in Neat Image. This function will automatically find and load a noise profile that best matches the specific device mode used to take a photo. This may be useful in situations when an image does not contain featureless areas and a profile cannot be built automatically.
