Good day! As a simple silent member of this group, I have noticed that a lot of our fellow newbie members are asking for tips and settings in order for them to improve on their skills. As such, a lot of our fellow experienced members are glad enough to respond with their corresponding tips in order to help the newbies. As such, a sudden wealth of information is dropped upon an unsuspecting new member of the community. This can be intimidating for someone who is new and has no idea that this much wealth of information is necessary in order to produce quality and amazing photographs. In line with this I am sharing this short, and hopefully helpful, guide in order to give proper direction to our newbies where to start learning photography.



As anyone would notice, any question regarding basic tips or settings, there is one specific answer that would appear 99% of the time, and that is the EXPOSURE TRIANGLE. Now, the Exposure Triangle in itself is a very basic theoretical foundation that every photographer must have a good knowledge on in order to elevate his skills and also master more advanced topics in this field. Thus I would like to introduce our fellow newbies to the Exposure Triangle.

Please take note that this guide is for beginners or whose knowledge about photography is close to or nil. For more experienced shooters, I hope reading this would remind you of your foundations. For our newbies, you can use this as a starting point for learning photography. This guide is short so no need to be intimidated. As any experienced shooter would say, knowledge of the exposure triangle is the bedrock in which this field of creativity and art rests.

Here we go...

The Exposure Triangle is a common way of associating the three variables that determine the exposure of a photograph: aperture, shutter speed, and ISO (https://fstoppers.com/…/exposure-triangle-understanding-how…). In this post I will tackle one of the variables of the triangle, the Aperture.

Aperture

The Aperture is the measure of the opening of the lens. It is controlled by a set of “blades” inside the lens that controls how big the opening is. The bigger the opening, the more light gets into the sensor, the smaller the opening, the less light gets in. You can think of this as similar to the pupils of the eye, when we enter a dark room, our pupils open wide in order to allow more light to get through our eyes so we can see better. When we enter a place that is bright, our pupils constrict to restrict light from getting inside.

You might wonder why we would ever want less light to reach the sensor. The answer the majority of the time is that we want a larger depth of field. Depth of field is a byproduct of aperture. Narrower apertures (higher f-numbers) give a greater depth of field, allowing more of a scene to be in focus (think landscapes). Wider apertures (lower f-numbers) create a narrow depth of field, which can help isolate a subject and is one of the greatest compositional tools at your disposal (think portraiture).

In summary (I told you this was short):

The smaller the aperture (bigger f-stop number), the wider the depth of field meaning more objects are in focus but less light can enter the sensor.
The bigger the aperture (smaller f-stop number), the narrower the depth of field meaning less objects are in focus but more light can enter the sensor.

Below are sample images that I took of my almost empty coffee drink. Both shutter speed and iso are constant in all images. Take note of the changes in the image as the aperture changes. All were taken with my Canon 80D and 24-70mm f/2.8.

Guide questions to ask yourself.
1. What happened to the exposure of the image as the aperture goes smaller?
2. What happens to the background of the subject as the aperture goes smaller? TIP: Look at the building at the back.
3. In which aperture is the background more blurred? Less blurred?
4. The depth of field is greatest in which level of aperture?

There are a lot more things about aperture that one can use in order to influence their image. But as for now, this is enough to get you started on practicing shooting while manipulating aperture. Good luck and keep on shooting!

I intend to complete this series. Watch out for my posts regarding Shutter Speed and ISO.

Bonus:
In every lens, there is a term called the “sweet spot” as it is the aperture where the image is sharpest for that particular lens. Every lens has a different sweet spot and finding that out is something you need to research on.
 
Thank You Michaela Baldos for your information but I have Sony camera and all of its features are totally different from Canon. Anyways I like your opinion about camera's. It's totally a lovable work for me. I used my camera to clicks pictures of Blogging and Home Furniture Deals site and all were love them:).
