Introduction to Exposure

I choose wildlife photography because, first of all, i am more a wildlife and nature lover, I love to spend time observing animals, in a early hours of the morning or late afternoon, it is just a pleasure for me to be part of the nature but you can choose anything you like to photograph, the process will stay the same.
Just have a look of what kind of photography we do at Nature Captured in Colour section and Black and White

Photography can be very complex but once we uderstand the concept, everything become clearer. They are three modes into your camera that you should have a look, for myself, i am using Nikon cameras but it’s the same with any other brands.
Aperture Priority, Shutter Priority and finaly my favourite one Manual Mode, where you can control everything.
This is just a brief understanding of Exposure, you don’t have to use them if you don’t feel comfortable with it but this will give you an idea of what to expect if you want to become a photographer.


Aperture (f-stop): you choose the f-stop and the ISO, the camera calculates the shutter speed.

Aperture values represent a ratio of focal length to diameter of the lens opening, therefore, F/4 or f=1:4 means that the aperture’s diameter is 1/4 the focal length of the lens. So with aperture values, the smaller number is a larger opening and lets in more light. The larger number is a smaller opening and lets in less light.

Shutter Priority

You choose the shutter speed and the ISO. The camera calculates the F-stop

Shutter speed represents a fraction of one second. Shutter speed controls the amount of light reaching the film, but also the degree to which subject motion is frozen or blurred.


Level of sensitivity of the camera to available light. Always stick to the lowest ISO to get the best quality image.
A hight iso will result of a lot noise on your images.

To understand, how you can start to take pictures on any other modes such as , Aperture Priority, Shutter Priority or my favorite one, Manual Mode.
Mark wallace explains it very well on his video, how to use exposure, a must see for beginners.

The key is to achieve the right balance to get the right exposure on your picture.

Your camera manual is your best friend so use it, you can find a lot informations about your camera settings.

The only way to achieve what you really want, only one word, PRACTICE, PREACTICE AND PRACTICE, there isn’t any secrets!!!

Introduction to the Rules

Composition, i think in my opinion, is the hardest part of making a picture, because there are so many things to think about it, the light, the background, and of course, it makes harder with wild animals, it will be great if we could ask them to place themselves, so patience with your subjects is really important.
To make your pictures more interesting , there are guidelines you should follow about composition and we call them Rules.

Many books are available for you to learn and written by famous photographers and it will really help how to compose.
On the following tables, i just give you five rules but there are much more than this.

Of course, you can always break the rules but before breaking them, you need to know them.

The rules of photography

Screen shot how i compose my picture, as you can see, i am using the rule thirds, The subject is place on one point but i wanted to keep the Horizon line, leaving the left space empty, I use a lot this rule because i just really like it, but you can also break the rules!!!
