A1: An external flash is more powerful for casting light into a far distance, or ensuring sufficient coverage when shooting with an ultra-wide angle length. The built-in flash (also called a pop-up flash) that comes with most cameras, including DSLRs and mirrorless cameras, is indeed very convenient to use

The main factors that will affect the quality of the natural light are the outdoor conditions and the time of day that you are taking pictures. The outdoor conditions being referred to in this tutorial are simply are whether the sky is generally clear or cloudy.

The size, shape and position of the windows. Reflections from surfaces inside the room. Reflections and obstructions from objects outside the room. All natural daylight comes from the Sun, by way of the sky.

You can use a flash to get rid of shadows from your photo. By adding in the extra light source you can minimise shadows by filling them in. Place the flash opposite the light source causing the shadows to achieve this. You can also use flash and a slow shutter speed when photographing a moving subject.

New flash units specifically designed for use with digital cameras don’t have this problem. But you can safely use your older flash unit if it is interfaced with a small shoe-mount device that slides onto the camera’s hot shoe before you attach the shoe-mount flash to reduce the voltage

Guide Numbers A flash guide number simply states how far the light will reach on optimal camera settings. A flash with a 120′ guide number is more powerful than a flash with a 60′ guide number. The flash with the higher guide number will be able to light subjects that are farther away from the flash

A little secret: Nearly all flashes made to work with digital cameras will work in manual mode with any camera, no matter which camera brand. Wireless Flash: Nikon, Canon, Pentax and Sony all have wireless flash systems which let you operate your flash off camera without the need for connecting cables or wires

Flash pulses have a duration of 1/1000 or thereabouts. So that’s 75 / 1/1000 = 75000 watts in that instant of a second. Conservatively, assuming we get 10 lumens per watt, 75000 x 10 = 750,000 lumens

Off-camera flash is a creative lighting technique that involves the off-camera placement of portable flashguns – or sometimes larger studio-style heads – to take control over the direction and intensity of light it produces

An on-camera flash, also known brand-wise as a “speedlight” or “speedlite,” is an indispensible accessory for many photographers; it provides additional light when conditions become too dark to handhold your camera comfortably, allows you to achieve more balanced exposures in daylight, permits freezing of fast-moving …

Off-camera flash is actually quite simple. All you need to fire a flash off camera is (1) a speedlight flash, (2) a trigger/receiver to wirelessly fire the flash, and (3) your camera. Also, infrared won’t fire the flash from very far way.

First, you want to make sure both the transmitter and the receiver are set to the same CHANNEL and GROUP! It’s a good idea to check the flash to make sure it’s on the receiver trigger entirely, or that the transmitter trigger is completely on your flash. If it’s not on all the way, your flash won’t fire.

The 430EX II doesn’t have this white card, but using its wide panel in the same position works just as well. That the LCD flashes is just a reminder that the panel is out, the speedlite still works using it that way

It appear as a caution symbol and when tapped, the message “Flash is disabled. The iPhone battery is low and needs to be charged before you can use the flash” comes up. This occurs no matter how much the phone is charged, even to 100%

In most cases these problems can be solved by simply turning your device on and off again. If problems persist, deleting the app and reinstalling it will often get it working properly again. As more is learned about the problem with Snapchat’s front-facing flash we’ll be sure to provide an update

Try shutting the Snapchat application and opening it again. This could refresh the application and make things run smoothly. Check the App Store for iOS or Google Play store for Android devices to make sure your Snapchat app is up to date. Turn your device off and then turn it on again

Main Solution Is to Reboot and Restart Snapchat Entirely simply close the app on your Android or Apple device and try opening it again. Sometimes apps like these just need to be opened and closed still to start working; it’s the first rule of IT, in fact.

Why does the volume randomly reach maximum on Snapchat? Turns out, this is a bug that was introduced with one of the latest updates to the app. While Snapchat may have tried to optimize the audio experience for its users, something broke in the process which causes the volume to randomly shoot up to its maximum limit
