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.

映像処理の専門家である知人と写真やカメラの話をしていたら、iPhoneでは良い写真が撮れないなどと言う。たしかに条件によってはプリントするとなると躊躇する場合もあるが、SNSで使う分にはかえって一眼レフより良く撮れることも多い。要は撮り方である。そうは言ってもなかなか理解するのは簡単ではないから、少し極端に撮って見たのが冒頭の写真である。若干の補正はしているが、妙な加工はしていない。iPhoneも侮れない。
