ND Filter EV vs Morseon

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

Morseon turns your iPhone into a complete Morse code toolkit for sending, decoding, learning, and practicing Morse code. Whether you’re curious about Morse code, learning it for the first time, practicing your skills, or simply need a practical Morse utility, Morseon brings the essential tools together in one place. SEND MORSE CODE YOUR WAY Type any message and instantly convert it into Morse code. Morseon can transmit your message using the capabilities already built into your iPhone: • Flash — send Morse code with the rear flashlight • Screen — use bright on-screen light signals • Sound — transmit dots and dashes as audible tones • Vibration — feel the rhythm of Morse code directly • Text — view the complete Morse representation of your message Adjust the transmission settings to match different situations and practice at your own pace. DECODE MORSE FROM LIGHT Point your camera toward a blinking Morse signal and let Morseon analyze the light pattern. The decoder detects changes between light and darkness, interprets dots and dashes, and converts the detected Morse sequence into readable text. It is a simple way to experiment with real-world optical Morse signals without manually writing down every dot and dash. DECODE MORSE FROM SOUND Morseon can now listen for Morse code tones through your microphone and decode them in real time. The audio decoder is designed to identify Morse signals while reducing interference from ordinary speech, music, and background noise. It supports common Morse tone frequencies and multiple transmission speeds, making it useful for experiments, practice sessions, recordings, radios, speakers, and other audible Morse sources. Watch the signal waveform, signal strength, detected frequency, and decoding status while Morseon works. LEARN MORSE CODE Morseon is not only a decoder — it can also help you learn the language behind the signals. Explore letters, numbers, and Morse symbols and become familiar with the relationship between characters, dots, and dashes. Listen to each code, observe its rhythm, and build recognition gradually. PRACTICE AND TEST YOURSELF Knowing the Morse alphabet is only the beginning. Use interactive exercises to strengthen your ability to recognize and understand Morse code. Practice repeatedly and improve your speed at your own pace. Whether you’re starting from zero or refreshing skills you learned before, Morseon gives you a convenient place to practice anywhere. A TOOL FOR CURIOSITY, LEARNING, AND REAL-WORLD USE Morse code has existed for generations, but it remains fascinating because it can be transmitted using something as simple as light or sound. Morseon lets you explore that idea using the hardware already in your pocket. Use it to: • Learn the Morse alphabet • Practice recognizing dots and dashes • Convert text into Morse code • Send messages with light • Send messages with sound • Decode flashing signals with the camera • Decode audible Morse tones with the microphone • Experiment with different speeds and signals • Demonstrate Morse code to friends • Explore one of the most iconic communication systems ever created SOS AND SIGNALING Quickly access recognizable Morse patterns such as SOS and transmit them using light or sound. Morseon can be a useful signaling companion, but it should not be considered a replacement for emergency services, dedicated emergency equipment, or professional communication devices. BUILT FOR IPHONE Morseon takes advantage of the camera, flashlight, microphone, speaker, screen, and haptic capabilities of your iPhone to turn a classic communication system into an interactive modern experience. No complicated equipment is required. From your first “… — …” to real-time light and audio decoding, Morseon gives you the tools to explore Morse code in one place. Send it. Hear it. See it. Decode it. Learn it. Discover Morse code with Morseon.
