The KYC series is going to be a set of mini-blogs where I talk about some features about your cameras. I hope this helps people use the camera better.
Lets start with a practically useful feature of your camera, called the ‘Highlight Alert’. A lot of people talk about histogram being extremely important and should be viewed for each image. I think this one is even more important.
The Highlight alert tool, blinks all the pixels on your image that have lost all details (completely over-exposed).
Take a look at the image below. If you look at the image on the right, you will see some red spots. Those are areas that have lost all details. Now imagine if you could look at it immediately after you click. The blinking captures your attention and correcting the over-exposure is then very simple. Just dial in a negative exposure compensation.
Another very common example that I see a lot is the Moon. If you are clicking the moon with centre-weighted metering, chances are that you would end up over-exposing the moon completely and end up with a white featureless blob. In such a case where you have completely over-exposed something, the highlight alert tool will start blinking the whites.
It is a very handy tool to checking which areas are over-exposed and if need be dialing in an exposure compensation to save the whites from being over-exposed.
A lot of times in the field, the LCD of your camera isn’t really clearly visible and you end up not seeing all the details in the image well. In such cases the highlight alert helps by blinking and ensuring that we don’t miss out on exposure blow-outs.
You can enable the highlight alert tool in your camera as follows
Depending on your camera model the menu options might change a little but by and large it should be similar to what is shown above.
Keep this one enabled and you will surely save a few shots someday 🙂
Now, I need some help on this series from you guys. In the comments section/message for this blog, put in any camera functionality that you are clueless about and I will cover it in one of the upcoming KYC series.
