Let me discuss about the back camera of iPhone 7 or later. Perhaps some of my readers may feel strange because such type of article is a bit far from my regular posts. In fact, usually I have taken pictures with a full-frame digital SLR camera and basically removed camera information, exif data for instance, in order to avoid discussion of specifications. Of course, in some cases including SNS, I really loves my iPhone camera. It is obviously easy to use.
A week ago, one of my colleagues asked me if I really took pictures with iPhone whenever I added hashtags for iPhones. I said sometimes I forgot to add them but had no reason to write untruth. A question was how can I make a bokeh without retouching. Perhaps as you know iPhone 7/8 plus or and X has a dual camera system and you can easily add a bokeh at portrait mode. However it’s not always easy. It may add an artificial effect on your pictures.
A picture I put here wasn’t given any artificial bokeh and taken with my iPhone 7 plus (iPhone X seems too expensive for me) a few days ago. Its focal length is about 4mm and it is obviously difficult to produce a big bokeh. At least 20mm is required even if f-stop is marked as f/1.8. A key is to set your lens closer to the object you want to shoot and find a good angle where the background is far enough.
