The best place to start to learn about photography

I'm often asked what is the best way to learn about photography. So many people have great digital SLR cameras and can take amazing photos but the first step that will make your photos look better is not only the equipment but learning the basics of photography first.

There are so many resources online that can teach you everything you need to know about photography theory. If you take the time to learn the technical aspects of photography such as shutter speed, aperture, ISO, focal length, colour temperature, etc it makes things so much easier down the track and will allow you to be a better photographer.

This is the article I always recommend that people read to start with, it can be a little confusing the first time but if you keep at it you'll master the basics of photography and you'll have a huge advantage in the future.

A Tedious Explanation of the f/stop

How big can you print phone photos?

Phones and digital cameras these days have a lot of megapixels and the amount of megapixels is often used as a selling point. I will discuss how megapixels don't matter as much as the marketers want us to believe and you can get great quality prints with lower resolution photos.

If you don't want to read all this below here's the summary in one paragraph:
Your phone in your pocket takes amazing photos and you can print them big, really big. The bigger you print them, the softer the photo will look but the further you will have to stand away from it so you won't notice that it's blurry.

To cover the basics first:
- a digital photo is made up of lots of tiny dots, these dots are called pixels.
- A 'megapixel' means one million pixels and the resolution of a 1 megapixel photo is 1000 x 1000 pixels (or little dots).
- The average human eye can see around 300 dots/pixels per inch at a distance of 30 centimetres
- the resolution of cameras are increasing rapidly over the years about our eyes will continue to only see 300 dots per inch (dpi) at 30 centimetres

When you look at a large TV with a full HD video the quality looks decent although a full HD video is 1920x1080 pixels which is equivalent to only a 2 megapixel photo. It looks ok because you have to stand far enough away from the TV so it's comfortable to look at and you can't notice that it's a low resolution image unless you walk up close.

A photo from an iPhone, GoPro or other 12 megapixel.
Lots of smartphones, iPhones, GoPros and point and shoot cameras take a 12 megapixel photo. This means the resolution of these photos are around 4000 x 3000 pixels (4000 x 3000 equals 12,000,000 pixels or 12 megapixels). This would mean you can print a 12 megapixel photo at any of these sizes:
- 8x10 inches: 400 dpi / much better than we can see
- 11x14 inches: 285 dpi / about the most detail we can see if we hold the photo 30cm away
- 16x24 inches: 166 dpi / still very good quality
- poster size: 111 dpi / if you looked very close, you'd see dots but would look decent at a metre away.
- A 12 metre billboard: 8 dpi / it would look low quality if you were close

This means if we print a 12 megapixel photo as big as a billboard and stand 30 centimetres away from it you will see eight dots in every inch. In reality we would never stand this close to a billboard and if we look at it from a normal distance it would look normal because the bigger you print a photo the farther away you'd have to stand to see it.

When megapixels do matter.

The reason though I like to have my photos very high resolution is because I like the fact that you can see a gigantic photo of a beach scene on the wall and then walk up super close to it and see tiny fine details and possibly even your own house

12 metre billboard for the International College of Management


This was an aerial photo taken for the International College of Management Sydney. It was taken with a Phantom 4 Pro at sunrise. After 3 attempts of getting up at 5am, the clouds cleared and I was able to get a series photos by stitching multiple photos together creating an almost 100 megapixel photo to be printed as a 12 metre billboard at Warringah Mall in Sydney's Northern Beaches.


This was the final result of an almost 100 megapixel photo
