Night Camera HD vs LabStretch2

Night Camera HD - the expert for professional nighttime shots on iPhone, iPad and iPod touch. AppAdvice 4.5/5 stars review: "Night Camera HD is a tool that every inclined mobile photographer should have." Thanks to the manual setting options for light exposure up to 1 second *, separate residual light- and ISO enhancement, Night Camera HD is perfect for taking pictures in a dark, insufficiently lit environment. Even during daylight, your pictures are clearer, with less interference, due to the extended exposure times. Take high-resolution photos in PNG format without visual loss. Forget about the loss of quality experienced with other cameras apps caused by image compression artifacts. Regardless whether you take night-, scenery- or other photographs, the picture quality you are able to achieve with Night Camera HD will surprise you. You can easy tap to focus and tap to exposure at the same time. After selecting the desired setting, you can easily lock it to prevent changes despite movement. Only here you can get luminance, luminosity and RGB histograms in real time to recognize over- and underexposure in time. The self-timer, which is imperative for nighttime shots, enables you to take un-blurred pictures. With the aid of the volume buttons you can take pictures with volume up (+) and fade the HUD-elements in- and out with volume down (-). Of course you can also block the white balance separately and edit it if necessary. Standard image formats (4:3, 3:2, 1:1, 16:9 and 3:1) can be edited live. The full-screen mode is activated for narrow image formats, enabling maximum display use. This feature can also be deactivated. The histogram adapts to all image formats. The up to 6x digital live zoom can be edited in the settings to enable a greater precision level during targeted zooming. Of course diverse alignment grids (e.g. Rule of Thirds, Golden Spirals and Golden Triangle) as well as a virtual horizon are available as overlays. Various real-time color filters complete this app. The most important functions: - Shutter speed control - Up to 1 second * exposure time - Manual ISO setting - Manual focus - Residual light enhancement - Real-time luminance histogram - Real-time luminosity histogram - Real-time RGB histogram - Self-timer - Volume Up (+) Photo Capture - Volume Down (-) HUD Hide - 6x digital live zoom - Tap to focus - Tap to exposure - White balance-lock - Manual white balance - Manual exposure adjustment - Various alignment grids - Virtual horizon - Aspect ratios: 4:3, 3:2, 1:1, 16:9 and 3:1 - Full-screen mode - Eco mode - Diverse color filters in real-time - Take HD photos - Landscape and portrait mode - Supports front and back camera - Supports LED-continuous light - Supports EXIF-data - Supports sharing via Facebook, Twitter *) Only on supported devices ---------- Please note that a minimum amount of light is still required.

LabStretch2 is a real-time image enhancement app, designed specifically for rock art researches to use in the field. Images can be acquired from within the app, or loaded from the iPad photo library. They can then be enhanced to see very faint color differences. Unlike the iPad version, LabStretch2 uses 2 screens, Settings and Image. The image thumbnail is also a Run button. For a description of the method, please see http://www.rupestrian.com/labstretch.html Usage Notes 1. Images are acquired by Capture Image, which takes a photo from within the app, or Import Image, which selects a photo from the camera roll. If you want to keep the image, use the camera and import the image from the camera roll. 2. Click Run. The image is downsampled and converted to Lab color space. The initial spread is applied. Try OffsetToggle to apply an estimated centering of the histogram before the multiplier (spread) is applied. Select the best toggle and then adjust the sliders. Run after each change. If the enhanced image is almost all one color, work with the offsets. 3. You can use the iPad screen capture to save results. 4. Use Save to capture the full-size enhanced to the camera roll. This requires considerable calculations and, depending upon your CPU speed, can take a minute or more. For assistance, please contact rockart@infomagic.net.
