How to DSLR Photography Guide


The brief way is the best way to learn how to use the DSLR camera. Since you are going to learn the most about taking pictures.

I am going to explain you the absolute basics and functions, so you can take good photos with a DSLR. I will describe everything on an EOS Rebel T6 so, if you have a Nikon or another brand things might be slightly different.

Understanding iso, shutter speed, aperture and how to work with them.

Iso:best way to learn how to use dslr camera

You have somewhere a button on your camera, that has ISO written on it. When you press it, you can change your ISO speed in my case from 100 till 6400.

What does it do:

It describes the sensitivity to light of your sensor 100= low sensitivity 6400= super sensitive. If you ask yourself now, why not always use a high iso? Because when you turn up your iso, your picture also gets an annoying and ugly noise.

How to use ISO:

Always try to keep the Iso as low as possible, to keep the noise low to only turn it up, if the light situation is so bad that you can’t adjust it through shutter speed or aperture. You can also use the auto function, but sometimes it selects a higher iso than required.

Shutter Speed/ Exposure:

The shutter speed describes the time the sensor is exposed to the light that comes through the lens (the Image).

How to use shutter speed:

A high shutter speed like 1/800 makes you able to freeze motion but it needs A LOT of light or a high iso. Because the sensor can’t capture a lot of light in that time.understanding iso shutter speed aperture


A low shutter speed like 1/50 makes you able to have a lot of motions in your image and a lot of light.

Warning: Be careful if you shoot without a tripod. You should always stay above at least 1/30, other ways you are going to have a motion blur in your image (that can look good) but usually, it is just sad. 😉

Aperture is, in my opinion, the hardest part of your camera to understand. It is a diaphragm located in your lens and looks like that.(you can’t see it on your camera).

How does aperture work:

On my 18-55mm kit lens, I have an aperture from f5-f29. Now comes the confusion a low number (f5), means that your diaphragm is wide open and f29 means it is almost closed.

If you shoot with a large aperture (f5) you are going to have a lot of light in your picture. Because it is wide open and a lot of light can get through, but also the range of your focus is going to be smaller (narrow depth of field)

If you shoot with a small aperture (f29) you are going to have a dark picture, because the diaphragm almost close and almost no light is coming through. You can adjust that darkness of cause with the iso or the shutter speed. The second effect that you going to see is, that the range of your focus is super long. (large depth of field)

.How to use it:

There is no right or wrong way to use it, since every situation is different and only you know what you want the picture to look like. If you want to isolate a single object in your image you can use aperture to blur the background.

What is the white balance:

To make it simple and easy to understand it is there to correct your colors, It tells the camera what white is, so the colors in the picture will look like the colors you have seen with your eyes when you took the picture.


You might have noticed that if you take a picture and look at it afterward the colors look totally different. For example, white looks blue for some reason. It has to do with the light temperature but I don’t want to confuse you with that. All you need to know how to use the white balance so you can adjust it.

How to use it:

On your camera, you will find some presents that are different from brand to brand just try them out and you will see. You will also find an auto function that always tries to adjust it right (and it does most of the time).

Manual: I actually only use the manual white balance when the auto function doesn’t work for what reason ever or when I want to use it as a creative element to give my picture a certain look.

If you haven’t got it right while shooting don’t worry you can fix that in Photoshop or any other photo-editing program. If you have any questions about that and want to know more just ask me in the comments. 😊

Different white balance settings:


I hope everything was easy to understand. I tried to keep it as brief as possible, because I think that the best way to fully understand these thinks, you need to take pictures and experiment. If you have any questions or opinions let me know in the comments. I will be more than happy to help you. 🙂

    I wish I had seen this post a few weeks ago. I get confused on the ISO settings a lot.

    I was helping out a friend and had the setting kind of high. We were indoors and the pictures looked fine on the camera even without much lighting.

    Then I opened them on the computer and boy were they grainy!

    I made up a phrase, “keep ISO low” as most of the time I am not looking for the noise.

    Hi Jeremy,
    Yes, I had that happening to me a couple of times too 🙂 keep ISO low is one of the best things you can do 😀 I always try to adjust through shutter speed or Aperture only if that doesn’t work I set it one higher. I also use to zoom in into every picture (the two buttons on the top right corner) to make sure it is as sharp as it looks like on the small display to prevent unwanted surprises.

    Hi Aaron,

    Thanks to your post I better understand ISO and aperture sizes. I’m more confident fiddling with the settings of my SLR. Always wondered why my photos turn out blurred when capturing motion – will have to use higher shutter speeds.

    Was wondering if flash affects these settings? I was thinking of buying one as an add on so I’m hoping the camera will figure out the necessary setups?

      Hi Dushan I more than happy that I was able to help you. 🙂
      Yes, it changes a lot because you have more light so you can use a faster shutter speed. If you want my advice, you should look for a flash that has HSS (high speed synchronisation) other ways you are going to have a black image when you go above 1/250 because the synchronisation between camera and flash is to slow.
      If the camera figures out the settings depends on your mode you are shooting in for example in M you have to set everything up but, in P the camera will do everything for you. I also depents on your flash type and settings if you use an external flash.
      I hope I was able to help you

    Great information on how to use the DSLR Camera.

    Camera’s or technology these days can be confusing so a decent guide on how to use is always welcoming.

    I have actually learned some things about cameras that I did not know. The had heard of the ISO before but had no idea that having it higher was probably a bad thing.

    I look forward to some of your future posts.
