Traditional black and white film photography is both an art and a science - while true of photography in general, there are some dedicated tools unique to this medium. Colored contrast filters can radically alter the end result by blocking portions of the spectrum of light hitting the film. This app is a live rendering tool that will help you to pre-visualize your scene and choose the appropriate filter for your shot. Conventional guidelines state that a yellow filter is a general purpose effect, red is for a very strong effect, g...

THIS IS A PROFESSIONAL APP BASED ON EVIDENCE JUST FOR PROFESSIONALS IN VISION SCIENCES ClinicCSF is an application to measure the Contrast Sensitivity Function (CSF) at one particular distance. This application can be used in vision science research to test CSF at any distance from 40 cm to 4 meters. This allows measuring the visual performance not only at far distance but also at intermediate and near for clinical studies with Multifocal Intraocular Lenses or Multifocal Contact Lenses. BEFORE TO BUY THE APP YOU SHOULD KNOW: T...

With its 2010 release, "Radiology 2.0: One Night in the ED" became the first radiology teaching file to simulate reading scans at a PACS workstation. The fifth instalment has now arrived: MRI Soft Tissue Contrast: Tissue Property Filters. Magnetic Resonance Imaging, or MRI, is a commonly used imaging modality in modern medicine yet the basics behind how this technology works is often poorly understood by the radiologists interpreting the images. Why are some tissues brighter than others? Why do tumours, traumatic injuries, or ...

King-Devick Variable Color Contrast Sensitivity Chart is an iPad/iPhone-based product application that allows clinicians to monitor and track the progression of Age-Related Macular Degeneration (AMD) from non-exudative (dry) AMD to exudative (wet) AMD. It is critical to know when exudative (wet) AMD begins to occur so the treatment with a-VEGF injections can begin. King-Devick Variable Color Contrast Sensitivity Chart has been proven to be a helpful tool in detecting progression of disease in Age-Related Macular Degeneration. Kin...

***A first special App for newborn‘s visual perception*** You‘ll be surprised by the reaction of your newborn - did you know Babies‘ visual perception doesn‘t work quite the same as adults‘? Research studies prove that in order not to be overwhelmed by the environment, Babies prefer to focus on high contrast and geometric shapes and patterns. Black, white and red contrasts are therefore more appealing to babies than bright colors. This App with a special auto play modus is designed to help newborn delevop their vision in the f...

Compare Contrast Connect (C3) is an app designed by teachers for teachers and students. It combines close reading, annotation, comparing and contrasting, deeper thinking, and synthesis. Any copied text can be pasted into C3 for in-depth analysis and with a few easy steps, a teacher has a lesson that both challenges students with rigor and relies on proven, tested strategies for literacy. There are four stages to C3: HIGHLIGHT Stage The Highlight Stage allows the student to read and highlight the two texts. Here they must highligh...

This medical test is to measure disturbed visual function in addition to classical visual acuity. Large test figures and variable contrast allow an examiner to quantify visual function when vision is strongly reduced and the classical acuity tests at a distance are not effective. The visual acuity is tested by showing a subject randomly oriented Snellen E’s with decreasing contrast and decreasing size until the subject is no longer able to recognize figures. The examiner presses a button according to the answer of the subject. Five...

The new app contrast by hornbeck enables you to take high contrast photos based upon available light, in a similar fashion to artist/photographer Johnathon Hornbeck. Clicking on either the shutter button or the picture itself to trigger the shutter, Contrast by hornbeck makes shooting from the hip or discreet photos easier, for capturing scenes in their true state or without drawing attention to the camera.
