Learn a photo from Exif data
Long time I didn’t post a photography article in my blog because I busy to work. The other reason is I don’t have something special that I need to write. This topic actually is a basic for photographer but it is essential ~ since I learn photography by myself, everything I do just read, read, read…… and of course try it. After that I write it on my blog ~ I think it’s good to share your experience for others, life isn’t just for you but also for others.
What is Exif? Exif stands for Exchangeable image file format, it is a specification for image file format used by digital camera. Exif usually content information such as date time information and camera setting. Learn Exif data is a fast way to learn other photography technique, of course learn the technique without good practice is just nothing. Anyway if you interesting about Exif in detail you can go to this link.
Let see sample photo below, I use ACDsee to see this Exif data, anyway you can use other software to open it, or just right click on your photo and choose properties then choose details.
See Exif data in detail, I just explain 2 sections that I think important:
Important things in camera section are camera model and date/time. The quality of the photo depend on the camera and lens ~ I agree photographer never blames his camera but I also agree that good photographer with good camera will produce good photograph. Date/time is important (especially) if you are landscape photographer. For example you want to take photo in Mt. Fuji, it’s better to check other people photo before you go there. If you learn others people photo you’ll get information the right time I should go there to take photo.
Almost all data in the image section are important. I usually learn this section from others photograph ~ it’s good to learn the technique and skill from others. If you see my photograph maybe you curious why the bokeh is good, tmaybe you want to ask me – but you think “how come he will tell his technique…”, anyway the answer already written in Exif data – just check the aperture value (f number) and focal length. Maybe you also like to know why the lighting and skin tone also nice ~ just check metering mode, white balance setting, and exposure bias. For sport photography and slow speed photography maybe you need to check shutter speed/exposure time. I can’t explain one by one in detail but I am sure you understand that it should be a reason for a photographer to set some value – learn it and for sure you will produce good photo.
Of course some photographers won’t let you learn his technique, so regarding this article maybe other people will criticize me why you teach people to “steal” such important information. So I will tell you how to delete the Exif data so other people can’t see it. The way is too easy, just use photoshop and click File->Save for Web and Devices. Using this way you can protect your technical photo information. Anyway the option to share or hide your photograph information is on your hand, in my opinion if you like to learn from others, you should like to share to others. Anyway comments, suggestions, critiques are welcome – thanks for visiting my blog.
