Mobile phone cameras have come a long way in recent years. Gone are they days where they'd take a grainy 1.2 megapixel image, which you couldn't make head or tail of. Camera phones now take fantastic images and are ideal for a lot of situations but if you are looking to up your photography game then you should upgrade to a DSLR and here are 5 reasons why.
1) Better quality photos
You may look at smartphone camera specs and see that it has 12 megapixels and then look at a DSLR that has 24 megapixels (or maybe even 16mp in older models) and think that that's not much more than your camera phone, so is it really worth the extra money to buy a DSLR? Well, image quality is more about the sensor size, than the number of megapixels. For example, the Samsung Galaxy S8 main camera sensor is 1/2.55", which is approximately 25mm squared. Now compare this to even inexpensive DSLR's whose sensor sizes starts at 225mm squared on four third systems and will go up from there. This means that a DSLR's sensor is over 10 times the size of even a high end smartphone of today.
2) Interchangeable lenses
Sensor size is one thing but if you want to take your images to the next level then you will want lenses that are designed specifically for the task in hand. Do you want to zoom into something at a distance? Then a DSLR has a choice of lenses for that. Are you taking portraits and want that aesthetic out of focus background (known as bokeh?) Then there are a choice of lenses for that. Do you want some macro shots of flowers or maybe even some ants? Then there are a choice of lenses for that. Smartphones have one focal length and even though you can buy lenses to fix onto your phone the phone itself isn't designed for that so the image quality suffers.
3) Deeper control over settings
Most smartphone camera apps are the equivalent of shooting on auto mode on a DSLR (even though some do allow you to change the settings this is more in-camera software altering the image). With a DSLR you have full control over shutter speed, aperture and ISO (I'll go over these in another blog post) as well as focus points. Once you have got use to all of these settings you can really master your images so that they turn out exactly how you want them.
4) Shooting RAW
RAW is a file type. However, unlike JPG the file retains all of the information in it meaning that you can edit an image just the way you like it pretty much without limitations. An example of the information that RAW captures is in the size of the files. JPG images can be 3-4mb, whereas a RAW file on my camera (a Canon 200d) is around 30mb.
Autofocus on smartphones is generally poor. The camera tries to get as much in focus as possible to be safe, whereas on a DSLR you have complete control over what you want to be in focus through choosing your focus point in camera. Also with systems such as Canon's dual pixel autofocus, DSLR's are really quick at focusing.
