How to use the “special” RGB Histogram

by 6 Comments

IMG_0506fA few weeks ago, I explained how to use the histogram to get a better exposure. And although the default histogram will give you a general idea of an image’s exposure, there’s actually a special histogram that’ll tell you a lot more: the RGB histogram.

Here’s how it works:

If you understand the regular histogram, then the RGB histogram is simple: it shows you the histogram of each individual color channel (red, green, and blue).

The bad thing about the regular histogram is that it lumps all these color channels together, making it hard for you to see if you’re underexposing or overexposing a specific color channel. And, on some cameras, I’ve heard that the regular histogram only shows you the green channel. [Read more…] about How to use the “special” RGB Histogram

Book Review: Digital Landscape Photography by John and Barbara Gerlach

by 5 Comments

Digital Landscape PhotographyI first discovered John and Barbara Gerlach about a year ago through Nature Photographer Magazine. I remember looking at their photos for the first time and just saying, “wow!” They seem to have mastered every type of nature photography: everything from wildlife to landscapes.

But, they’re not just amazing photographers, they’re also pretty awesome writers. I always look forward to their clear and useful articles in Nature Photographer Magazine. I’ve already shared a lot of what I’ve learned from them here on PhotoNaturalist, like how the Live Preview on your camera can help you take better photos.

So, when I heard about their new book, Digital Landscape Photography, I immediately ordered it on Amazon!

Well, I’ve had a chance to read it, and look through it again pretty thoroughly, so I thought I’d share my reaction to the book. [Read more…] about Book Review: Digital Landscape Photography by John and Barbara Gerlach

How to check sharpness out on the trail

by 2 Comments

IMG_0476bIn last week’s post, I explained how to use the histogram to check if you exposed a photo properly. Another thing you probably want to know after taking a photo is whether or not it’s sharp.

Well, one way to see if a photo came out sharp enough, is to zoom in as much as possible on the LCD preview.

This won’t show you exactly how sharp the photo is, but it’ll give you a much better idea than just looking at the zoomed out preview (which almost always looks sharp). [Read more…] about How to check sharpness out on the trail

How to use the histogram to get a better exposure

histogram-titleOne of the first things you probably want to know after taking a photo is whether or not you got your intended exposure.

You might be tempted to look at the preview on your LCD screen, but when you’re shooting photos outdoors in the sun, those previews can be very deceiving, making your photos look much brighter than they actually are.

So, how do you know if you got the right exposure? Well, one way is to use the histogram. [Read more…] about How to use the histogram to get a better exposure

How To Get Better Control of Autofocus

by 9 Comments

IMG_0482cSometimes autofocus can be really annoying. For some shots it’ll focus on the right part of your subject, but then the very next shot it may choose to focus on something far and away into the background.

In a previous post, I shared a few ways to avoid problems like this, but I just found a new solution that I like a lot better: back-button autofocusing.

Here’s how it works:

Normally, your camera will auto focus when you press the shutter button halfway, but with back-button autofocusing, you have to press a button on the back of the camera instead, giving you complete control of when autofocus is initiated. [Read more…] about How To Get Better Control of Autofocus

“Wow, you must have a really good camera!”

Anyone who has ever taken a sharp, properly exposed, and well-composed photo has heard these very words.

A couple of years ago someone I know, a writer of three published books and numerous articles, came across some of my flower photos. He looked at them intensely and said, “Wow, you must have a really good camera!”

I stared at him looking perplexed then smiled and said that I thought his writing was excellent and that he must have a “really good keyboard and computer!” He understood. [Read more…] about “Wow, you must have a really good camera!”
