Pop-up flash basics
You can’t beat a flashgun for versatility, but if your camera has a pop‑up flash it can be a great way to add light to subjects. Using a pop‑up flash can be as simple as pressing the flash button and shooting, but if you find the flash is too strong or too weak, you can use flash exposure compensation to adjust the power. This may be accessed in the main menu or via the Quick menu. If using a flashgun, you can also set flash exposure compensation via controls on the flashgun itself.
