Nikon D90 books

This has nothing to do with whether it is D90 or not, mainly because you haven't mastered the specific subject. The instructions only tell you how to use it, not how to use it under any circumstances. This requires you to study and recommend a classic course of the New York Institute of Photography. The book consists of two volumes, which is a classic course of photography from entry to mastery. At the same time, you can also go to the website of Green Shadow Promise to learn more, look at the photos you are interested in, see everyone's discussion, and then practice by yourself. Only by practicing constantly and summing up your own experience can you improve. I suggest you download a software exif to view the exif information of photos. With this software, you can basically view the EXIF information of photos on the website by right clicking, including camera, lens, aperture, shutter, white balance, ISO and a series of shooting parameters. This can also help you study, but some websites will automatically delete EXIF information after uploading photos, and some image processing software will also delete EXIF information. But it should be said that most photography websites will keep EXIF information unless the author deletes it when processing photos.
