Lumu Light Meter vs Light Lamb

The light metering tool for every great image maker. Use the standalone app as a reflective light meter or use it in combination with Lumu Power hardware for professional Flash and Color Temperature measurements. Lumu Power is an easy-to-use digital incident color and light meter that works seamlessly with the free Lumu app to deliver Color Temperature, Illuminance, Spot, Ambient, and Flash Exposure metering functionality on your iPhone. A new expression of what a light meter can be, Lumu meets the needs of enthusiasts, professionals, and students who find existing light metering solutions too bulky, expensive, and complicated. “The Lumu Power is without any doubt the most full featured light meter I have ever owned. It’s tiny, it weighs hardly anything, it manages to offer a feature set that expands way beyond what most will ever need from such a device.” - www.35mmc.com Key features: - SPOT METERING: Use your phone’s camera as a reflective light meter. With Lumu Power: - PHOTO SINGLE mode: Giving you exact parameters: exposure time, f-number, ISO, EV, lux. - PHOTO MULTI mode: Calculating average value or contrast between multiple measurements. - PHOTO PINHOLE mode: Measuring exposure time for custom pinhole camera settings. - CINE/VIDEO mode: Set FPS, F-number, exposure time and ISO. Get the values for the ambiental light. - FLASH EXPOSURE: See the graph of flash duration, measure its intensity. - COLOR TEMPERATURE: Read light Color temperature in Kelvin and Green/Magenta shift. - CHROMATICITY: See light colour in CIE1931 diagram and get X,Y,Z coordinates. - ILLUMINANCE mode: showing incident light level in lux / foot-candle values. - NOTES: Store all your measurements together with geo-location, custom notes and your photo in one place. + ND FILTERS, EXPOSURE COMPENSATION and more… Visit http://lu.mu/ to learn more.

Light Lamb is a free photographers’ light meter app for iOS. You can let Light Lamb decide everything for you like getting an auto mode for your manual film camera, or you could have full manual control of the parameters, or whatever you want in between. - Now with histogram (New in 1.3.0) Use the histogram to make sure the scene is exposed just like how you envisioned. - From full auto to assisted manual control In most cameras if you pick a parameter like aperture, shutter, or ISO, the camera would stick to your chosen values even if it's too dark or too bright for the scene. The reason we made Light Lamb is to have a light meter that would suggest different settings if the chosen parameters are not suitable. For example, you can keep your settings at f/8 and 1/125 for deep depth of field and fast shutter speed, but if it's too dark, Light Lamb would suggest brighter values to make sure it's correctly exposed. Or say you want to set the aperture to f/1.4 for shallow depth of field, and if it's bright outside and the shutter is already at its fastest speed, Light Lamb would suggest a smaller aperture. Just set the parameters to what you want and Light Lamb will handle the rest. - Safe shutter-aware Pick a preferred slowest shutter speed you want and Light Lamb will match it. If the scene is too dark, Light Lamb automatically pick a slower shutter speed beyond the safe shutter to achieve the correct exposure. - Spot metering Zoom in 5x to focus the measurements to small areas in contrasting scenes. - Match your equipment Choose the range and increment of ISO, aperture, and shutter speed to match your equipment. Choose between whole-stop, half-stop, and one-third EV increments for each parameter. - Keep a memo Keep a memo of the settings used, including a photo of the scene and the location. Export it as a beautiful picture note formatted in 4:5 aspect ratio, great for posting to Instagram along with your photo.
