The ultimate still photo app for the conscious image maker - works equally well for serious photography as for organized visual note taking. With a handful of unique features you'll not find anywhere else. Photos are saved to individual albums created with a specific purpose in mind. Such as different photo shoots or projects, visual shopping lists, recipes from the grandmother's cookbook, things for sale, monthly gas and electricity meter readings - the list is endless. These uses need different image qualities and sizes (you'll seldom make a large print of a meter reading, for example), so the app has: • Album specific image quality, color space (wide color capable devices only) and geotagging settings. • Selectable image quality with full, half, quarter, high color fidelity quarter HQ sizes and a super tiny 0.48 megapixel 800x600 JPG, as well as RAW and RAW+JPG on devices supporting RAW capture. The 800x600 JPG is up to 20 times smaller than a regular JPG, making it extremely gentle with your mobile plan's data allowance. • Color space can be set to Display P3, Adobe RGB or sRGB for JPG files and Adobe RGB or sRGB for RAW previews. • Home screen Quick Actions for selecting the last recently used three albums. Unique features include: • Framing Previsor for showing on the wide angle camera's image what the telephoto camera would see.* Also works with wide converters. • Highlight and shadow alerts. • Protective exposure metering. • Auto ISO with minimum, maximum and minimum shutter speed settings. • Real time distortion correction for wide angle converters via correction profiles, as well as a custom converter for other lenses.* • Selectable screen frame rate to balance between fluid experience and power saving, and to avoid flicker with lighting running on 50Hz mains frequency. • TIFF/EP compliant DNG files with support for wide color and full resolution embedded previews. * Utilizes the time-tested precise simulation and distortion correction engines of our Mark II Artist's Viewfinder app. Other notable features: • Manual control for ISO and shutter speed in 1/3 stop increments. • Manual focus with focus peaking. Selectable peaking color. • Exposure compensation up to +/-5 stops. • Exposure and focus lock. • Continuous and single AF modes. • Grid display with 2x2, 3x3 and 8x6 choices. • Luminance only Black & White mode. • Artist and copyright metadata. The copyright template supports tokens for the current year (so it's always up-to-date), artist name and the copyright symbol. • Four user-assignable Smart Function Keys to bring most-used functions to a single tap distance, with 7 functions to choose from. • Completely neutral viewing to avoid interfering with your color vision during composition. • Fully color managed, from capture to display, including color-correct display of wide color RAW images. Technical Camera only supports the back camera(s) in still photography mode. No videos or selfies. No fancy filters. The Framing Previsor requires a dual-camera device or a wide converter lens. The complete list of supported wide converter lenses can be found on the Tech Specs page: https://www.direstudio.com/technical-camera/tech-specs/ For more information we recommend to check out our Technical Camera How To's: https://www.direstudio.com/technical-camera/how-tos/
