CameraTestSlate
turns your iPhone®, iPad®, iPod Touch®, or Mac® into a wireless data slate so you can update on-camera test info from behind the camera. Info resizes to fit the space available. CameraTestSlate is color-balanced for 3200 K, 4300K, 5600 K, or 6500 K (and can show that color temperature onscreen), and you can choose light or dark mode slates.


How To Use It

Launch CameraTestSlate on your slate device. It displays any information previously entered, and shows you a Connection Info alert:

Connection Info box

Tap OK to hide the alert, or just open the webpage on your controlling device. If you want to see it again, tapping the screen shows the alert when it’s hidden.

If Connection Info says, “No connection; can’t run web server”, make sure that Wi-Fi is turned on (or that a wired network is connected), and that there are no other web servers running on your machine. You might need to turn Airplane Mode off. Then close and reopen the app.

Open a browser window on your controlling device. Use the slate’s local name if shown, or its IP address. Enter any information you want displayed, and select the color temperature and display options.
