从TIF-imag读取和写入Python中的exif元数据

Question

我在Python中寻找一个库或一个特定的函数，用数码相机从TIFF图像中读写exif metadata

16位TIFF格式的图像具有以下属性，标识为ImageMagick：

Properties:
date:create: 2015-09-02T16:01:49-06:00
date:modify: 2015-09-02T18:00:37-06:00

exif:FNumber: 2.8
exif:FocalLength: 16
exif:ISOSpeedRatings: 400

tiff:alpha: unspecified
tiff:artist:
tiff:endian: lsb
tiff:make: Sony
tiff:model: NEX-7
tiff:photometric: RGB
tiff:rows-per-strip: 1
tiff:software: dcraw v9.25
tiff:timestamp: 2014:07:28 08:34:56

如果我用Python和comumnlibreries（es:tifffile）读写，我就会丢失元数据

您可以使用Wand：

from wand.image import Image

with Image(filename='test.tif') as image:
    for k, v in image.metadata.items():
        print("{}: {}".format(k, v))

    image.save(filename='copy.tif')
