Teradek Prism vs LightTemp

Keep track of your live stream from your smart device with the Prism app. Easily monitor your video and audio feed, while reviewing stream stats like bitrate, bonding status, and network health. And take it one step further by enabling hotspot bonding with multiple cellular devices for fast, reliable internet connectivity wherever you go.

LightTemp turns your smartphone into a professional on-set tool: measure light, understand it, and keep it consistent across the whole shoot – no expensive hardware required. Built by a filmmaker, for filmmakers. ◆ REAL-TIME KELVIN & TINT Point your camera at a light source and instantly read color temperature (Kelvin) and green-magenta tint. Tap the image to measure that exact spot (double-tap = center). Perfect for scouting and quick lighting checks. ◆ CAMERA WB RECOMMENDATION LightTemp tells you exactly what to dial into your camera – the measured value IS your white balance. ◆ LIGHTING RATIO (LIGHTING DESIGN) Measure Key, Fill, Back and Background one by one – the app computes the contrast ratios in stops (e.g. 4:1). Turn "reading a number" into "designing your lighting". ◆ GEL CALCULATOR Pick source + target white point – the app calculates the right CTO/CTB gel using real mired math, including combining large corrections. ◆ SHOOT SETUP & SHOT MATCH (CONTINUITY) Set your cine camera once (model, EI, fps, shutter angle). Save each scene as a full snapshot – Kelvin, tint, lighting ratio, flicker note and your camera values – and reproduce the lighting exactly on the next shooting day. Export as PDF. ◆ CONTINUITY RADAR Anchor the current light and the app warns you – with a banner and haptic – the moment color temperature or tint drifts, with a correction tip to get back. Keeps your look consistent across takes. ◆ MULTI-POINT DEVICE CALIBRATION Calibrate LightTemp with several reference points into a precise correction curve – maximum accuracy on your exact device. ◆ AUTOMATIC LIGHT SOURCE DETECTION Recognizes Tungsten, LED, HMI, daylight, candlelight or fluorescent – including a flicker warning (banding risk). ◆ PRO SCOPES • Histogram – brightness distribution • Waveform – luminance across the image width • RGB Parade – red/green/blue separately for a quick white-balance check ◆ FALSE COLOR & ZEBRA Exposure overlays like on professional monitors – correct skin tones, clipping and overexposed areas at a glance. Plus a live exposure assistant. ◆ GOLDEN & BLUE HOUR Calculates the sun's position from your location with a countdown to the next phase – for scouting. ◆ MORE TOOLS • Live camera data: ISO, shutter, aperture, FPS • Pinch-to-zoom • Freeze to lock the value • Customizable tool bar • Kelvin alarm (vibrates at target value) • Four languages: English, German, French, Spanish PRIVACY All data stays on your device. No accounts, no tracking, no ads. Note: Accuracy depends on your device's camera; use the calibration for best results. LightTemp is an assistive tool and does not replace a calibrated hardware light meter for the most demanding use.
