What Is Histogram And Why You Have To Use It


Recently I’ve shared a few videos and tips about technical details for landscape photography.  As a matter of fact, no matter if you are into photographing landscape, people, or animals, one of the most important tools in your camera that you HAVE TO know is histogram.  It helps you, a beginner or experienced amateur photographer, to manage the MOST FUNDAMENTAL technical aspect of any photos you take – getting the exposure right!

What is histogram?  You might ask.  Here’s a photo of my camera.  On the upper right corner of the screen, you’ll see the histogram.  Every camera has a slightly different way to display histogram, but fundamentally it looks similar to this – a rectangular with shapes of spikes or curves in between.

To access to your histogram, the best way is to look at your camera’s manual.  As I explained in the following video, even cameras of the same brand use different buttons to access to their histogram.  Once you find it, you’ll find the most fundamental treasure to improve your photography!

  1. Hi Belinda love your tutorials, I have a question when you put your sd card in computer and lightroom comes on and you select a folder to put your pictures in. Your raw files are on the computer and in lightroom, once you process your pictures and you change them to jpeg. why do you still need the raw files on computer can you delete them they can’t be seen any way, and they are already in lightroom.
    Thank you very much Belinda….

    Hi Gary, great question. If I have to delete files, I’ll delete jpeg not RAW files because the latter contain the most complete data of your photo files. You can process RAW files and fine-tune them later – a necessary process if you ever deal with printing, 3rd party professional lab etc. which require you to calibrate your monitor with theirs, and thus very often you need to re-do your editing. Once you export your file into Jpeg, which is a compressed file format, you lose lots of data that can’t be recovered. Unless you absolutely know for sure your Jpeg is the final version that won’t need to be edited again, and/or you are running out of disk space (since RAW files are much larger than Jpeg), I would save RAW files. Last but not least, RAW files can be seen outside of Lightroom, such as in Finder preview if you use Mac. Not sure what you mean “they can’t be seen”. I hope this helps. Feel free to let me know if you have other questions.
