You may find it best to crank up the ISO sensitivity to 1,600 or 3,200 because you'll be shooting mostly in the dark. Step two: Now is a good time to turn off the lights and determine the correct exposure for the light coming from the screen. You may need to adjust the height and positioning until the camera sits directly in the centre of the middle black circle. Put the camera on a tripod and position it in front of the screen.

However, a traditional ring light or ring flash can be an expensive tool. It is an ideal tool for portraiture or close-up work because there are no shadows cast from the light. (Enter the BIOS setup by pressing a key when your computer first boots, usually something like Delete or F2-the boot screen will tell you.Using a ring light or ring flash helps to produce nice, even light across your subject's face. If your computer doesn't stay asleep after this, you might also try entering the BIOS and disabling USB waking from there, if you see an option for it. Select Properties and the Power Management tab, then uncheck the Allow This Device to Wake the Computer option and click OK. Once you find the problematic hardware, open the Start menu and search for "Device Manager." Find the device in the resulting list-say, your keyboard-and right-click on it. Keep doing this until you find the offending device. If it doesn’t, leave one device plugged in the next time you put it to sleep.

I’ve also had luck searching Windows’ Event Viewer for information. If that command didn’t give you useful information, try this one: powercfg -waketimers In other cases, it may list a specific hardware device, and you can skip down to the relevant section in this article, or do web search for what settings to change on that device. In that case, your search is over, and you can adjust that program’s settings or uninstall it to stop the problem. For example, the last time my workstation woke up, it was due to my cloud backup program running its scheduled backup for the evening. If you’re lucky, it’ll give you a clear answer. Type the following command and press Enter: powercfg -lastwake Windows knows what woke up your computer most recently, so the next time it wakes up unexpectedly, open the Start menu and search “cmd,” then right-click the Command Prompt and choose Run As Administrator.
