Theta vs ND Filter EV

Theta-Meter X Theta-Meter X is a companion application designed to work with compatible Theta-Meter hardware devices.  The app connects via Bluetooth Low Energy (BLE 4.0 or higher) or Wi-Fi and displays real-time electrical resistance  measurements from objects connected to the device’s electrodes. Key Features: - Real-time visualization of electrical resistance changes - Clear analog-style needle indicator for dynamic monitoring - Bluetooth LE and Wi-Fi connectivity - Simple, user-friendly interface - Stable data transmission from supported hardware devices How It Works When connected to a compatible device, the app measures and displays variations in electrical resistance detected between  attached electrodes. The needle indicator provides a continuous visual representation of resistance fluctuations, allowing  users to observe dynamic changes over time. Intended Use Theta-Meter X is designed for general experimental, educational, and technical purposes involving electrical resistance measurement.  It is intended for use with compatible hardware devices only. Important Notice This application and the associated hardware are not medical devices. They are not intended for diagnosing, treating, curing,  preventing, or mitigating any disease or health condition. The app does not provide medical, therapeutic, or psychological advice.

This is a calculator for photographing using ND (Neutral-density) filters with any number of stops. ND STOPS lets you set the exposure without ND filter in a blue field, and see the result below. EV ALTERNATIVES gives you a dual combo alternatives of ISO, APERTURE and SHUTTER SPEED SWEET SPOTS is not always accurate, but in many cases lenses has its sweet spot at about 40% up on the aperture range. SETTINGS lets you choose which stops you want to see in the ND STOPS PAGE and at what EV (exposure value) interval in all pages. To see more apps like this, go to www.discobajas.com
