I understand that EXIF data is important because it helps one to understand the technical aspect of the photo. However nowadays, with the widespread use of PP, does the EXIF data comes in useful? Because most photos would have gone thru at least tweaking of contrast and sharpness. Hence the what is shown on the photo is no longer a real reflection of the camera setting. (Ok, sharpness is more a product of lens prowess).

Hence, how is exif useful?:think:

EXIF data covers a broad spectrum of information, more than just camera details but also information of the photo like when and where it was shot, subject, title or description of photo, copyright information, name of photog, keywords etc. These information would be useful when a photo is disseminated widely and perhaps in media/press is to avoid wrong data entry, captioning for instance. Also, nowadays, most stock libraries or online photo gallery are capable of reading these data and would eliminate the need of you entering the data manually too.

When I give my photos to my clients, I will usually remove the camera technical info but will have the other details as mentioned above. It's actually called IPTC, short for International Press Telecommunications Council, made to describe and administrate photographs. IPTC is stored within EXIF data.

some things still cannot be pped

e.g. water motion. if you can pp out water motion present in a 2 minute exposure from a short shutter speed exposure, please let me know :D

anyways, people sometimes just want to know,personally, asking HOW the person did it, rather than asking for specific parameters (which are frankly, fluid)... would be the right question

sometimes, asking the right questions is more important than getting the right answers

Oh for own use is useful because like you said, I also learn from my bad shots. Sometimes from the small LCD, everything looked nice till it is reviewed on computer screen

I understand usefulness of the IPTC and removal of the technical data for commercial use.

But in sites like clubsnap, where there is a learning platform, exif is useful for learning purposes. But with PP. the technical details is no longer reflected in the photos, so how useful will the technical details be?

If it cannot be PPed then the tech exif is useful because it is reflective of the camera settings esp for moving water because the sl changes in shutterspeed/aperture may mean fantastic shots for a disastrous one. And yes, if you can pp out water motion, I also want to know :bsmilie:

Well said. how a photo is taken is probably more important than what lens, setting, etc because there are so many confounding factors.

Having said that, I sometimes look at exif to see the "limitations" of my camera/lens (aka my limitation :sweatsm:) because if someone else can capture nice shots with same lens then it make sense that limitation is not with equipment :(. So, no need to buy new lens
