So for my cover photo, I want it to have a shallow depth of field just like the one seen in the previous blog. Now since I have very little experience in taking professional photos or anything photography related, I'm going to have to research my butt off so that these photos will look presentable. In this Blog I will go over a few things:
- Shallow Depth of Field
- How to achieve it in Manual Focus
- Bokeh
- How to achieve that (blurry/out of focus) background
What is a Shallow Depth of Field
What a shallow depth of field is in photography is a effect where only a small portion of the image is in focus (typically which object is closest to the camera) and the rest of the image (background) is out of focus and "blurry."
As seen in this image, the shot on the left is used without a shallow depth of field. Now looking towards the right, we see the effect and we see how the image is enhanced so that more of the attention goes towards the subject which is the woman.

How This Looks In Food Photography
To me this is such a great photo, not only because of the shallow depth of focus, but also the framing and positioning of the food. But that's besides the point, we see this shallow focus as we only have one Macaron in focus even though there is another one less than a few inches behind it.

How to Take Shallow Depth of Field Shots
Article by: https://digital-photography-school.com/how-to-get-shallow-depth-of-field-in-your-digital-photos/
The first note that I took from this article was that in order to make the subject appear far away from the rest of the photo, I have to bring it as close to the camera as possible. The closer it is to the lens = the more farther away it looks from the background.
Second note I took from this article is that I have my lens's aperture wide. What this means is essentially the more wider the aperture is, the shallower the depth of field will appear. In order to have my aperture wide, I need to have the numbers at either f/1.8 and f/2.8 to have the shallow depth of field. Whereas if I were to use larger numbers such as f/16 and f/22, this would creater a deeper depth of field meaning more focus to the back of the image.

The next note that I have from this article is that it is recommended to use longer lenses to achieve the shallower depth of field. But this is where I'll divert on my own path. In the article, they recommend using a 85mm lens or a 70 to 200mm lens. In the article they specifically mention "not a 50mm or a 35mm lens." Which at first, had me worried. Because that was the type of lens that I would be working with. (A 50mm cannon lens). But then I realized that the only setback that I would face is that I would just have to be a lot closer to my subject rather than if I was using a 85mm lens. Which shouldn't be a problem.
What brought my confidence up was the next step in this article. Which mentioned having a wider aperture lens is such a benefit compared to other lenses. They specifically mentioned using a 50mm f/1.8 and said it was "optically impressive, and capable of beautiful background blur."
In the next blog, I will continue this research and go further into depth on Bokeh and achieving that blurry / out of focus background.
Bokeh
What Bokeh is, is the specific region of the photo that is out of focus or seen as "blurry."

Now how this looks in food photography:
