Drew Black broken crankshaft 8011 Posts 9/99	Posted - Feb 5 2007 : 10:27PM No this is not a poll. I've been working on a project for a client's site and got to poking around with Exif data in photos. Just curious if people find it useful? I see sites like Flickr make it available if the info is embedded in the image. [Link]

Leyden Senior Member The people have spoken. I'm a nitpicking dick. Woo! 8757 Posts 1/04	Posted - Feb 5 2007 : 10:54PM It can be cool for a little gag... say you and a bunch of others are somewhere shooting an event. You ask everyone to send you some pictures. They send some. You peek at the EXIF and write back and say, "hey great job with that Olympus XYZ camera!" They write back soon after, "How did you know I had an Olympus XYZ?" And you just smile. A weird thing... if I resize or edit in Irfanview the original EXIF is retained. If I edit in PSE it goes bye-bye. [Link]
Drew Black broken crankshaft 8011 Posts 9/99	Posted - Feb 5 2007 : 11:30PM I think the general rule is that if an image is optimized/saved as for use on the web (typically 72 dpi) the Exif data is dropped. Each photo editing program handles it their own way but that seems to be the norm. I was poking around on Flickr tonight and noticed the Exif data on some images. I'm curious about stuff like that but have no idea if the general public cares. [Link]

jrv Senior Member 1266 Posts 2/03	Posted - Feb 6 2007 : 12:38PM I sometimes look at the EXIF data if I suspect I made a particular mistake on a shot and want to see what exposure settings were actually used. I add IPTC data to photos I take for a roof engineering firm to note all the job and copyright info, etc. On a couple of occasions the EXIF timestamps have been useful. Many of their pics are used in litigation and I double-check the dates to make sure the prints are labeled correctly. [Link]
Tinaka Member 953 Posts 8/03	Posted - Feb 6 2007 : 7:36PM yes i do. especiially from paparazzi. eg: 02-01-07 Honolulu, HI Denise Richards and Richie Sambora On Hawaii Vacation together. The happy couple played in the ocean together and enjoyed time together on the beach under the sun Richards even showed off her crotch to our photographer... [Link]

RandomPrecision Senior Member Enjoy! 8175 Posts 3/06	Posted - Feb 7 2007 : 8:55PM Yeah. I always try and make sure the Exif info gets saved. I play around with my camera settings a lot and find the data very useful for figuring out how a particular picture turned out so good (or bad). Plus, dates and times are nice to have for reference as well. Good stuff. [Link]

Click to expand Yep. And you can often tell how much thought and care the photographer put into the photo just by looking at the Exif. If everything is on auto and the picture looks like crap, well, there's why. [Link]
DrP0rn0 Senior Member 1836 Posts 5/04	Posted - Feb 28 2007 : 12:13PM EXIF is also important because it tends to retain the date and time the shot was taken, as opposed to the file's date and time, which can be when you last edited it, when it was downloaded, etc. I guess it mainly depends upon the needs of your client. I personally find it useful, but it might have no utility depending upon what the site is for. Dr. P Edited by - drp0rn0 on 2/28/2007 12:14:18 PM [Link]
RandomPrecision Senior Member Enjoy! 8175 Posts 3/06	Posted - Feb 28 2007 : 6:36PM I don't see any reason why the Exif data should ever be discarded, really. You never know when it's going to come in handy or for what reason. [Link]
Drew Black broken crankshaft 8011 Posts 9/99	Posted - Feb 28 2007 : 8:13PM Yes, I agree that the original photographer shouldn't discard exif data but what about sites like Flickr that make exif data available to perfect strangers? Are there privacy issues? [Link]

Are there privacy issues? Click to expand Not really. Maybe. The EXIF data can contain the camera make and model. You're advertising you got one. Or, maybe you showed the client a $$$ Canon 1Ds m2 when signing up for the job but had to use a Canon 20D on site - want to admit it? (hokey I know but I'm trying) The EXIF data can contain the serial number for the camera. If an expensive camera body of mine gets stolen you can bet I'll try to think of ways to search periodically in case it shows up when someone posts a pic from that body on a web site. Low chance of success, but... Also, my cameras all embed my name in the files but I'm not sure where, EXIF-happy sites might display it (or maybe Google will be able to search on EXIF one day). The EXIF can contain GPS data if it was available to the camera, including location, time and velocity/speed. Out past curfew? Trespassing? Speeding? Probation? Lastly, EXIF can contain copyright and shooter/editor information (IPTC is where this is usually put, but there are EXIF fields for it too). If you post it and say it's yours, but someone else says it's theirs, and EXIF agrees with them, is that a problem? Reasons for retaining EXIF: litigation. I never modify or edit a pic for the structural engineers unless absolutely necessary, and if so the delivered package contains both retouched and original. If the roof of a shopping mall caves in - hey, stuff happens, you know? - there will be lawsuits, and I always prefer to be able make simple straightforward claims even a lawyer can understand, ie, That Pic Has Not Been Changed in Any Way By Anything, Period.

Are there privacy issues? Click to expand Well, I guess that's a point. As long as the EXIF doesn't get so detailed and meticulous as to include my name, address, phone number, date of birth and soc security number, I wouldn't mind. I don't think my camera puts the camera serial number in there. The most private info it puts in there is the make and model, which isn't a big deal. It could be problematic if they go too far with it. a lot of people probably don't even know the info is there. [Link]
ChodeMasterJ Perpetual Marxist 5405 Posts 4/03	Posted - Mar 1 2007 : 3:59AM how do you access the EXIF data from, say, some pictures you took with a snap and shoot digital camera? or is it not saved for lower end stuff? [Link]
Drew Black broken crankshaft 8011 Posts 9/99	Posted - Mar 1 2007 : 11:00AM you try this one. I've never used it but it should do the job. [Link]
Tinaka Member 953 Posts 8/03	Posted - Mar 1 2007 : 12:31PM I always use my trusty IrfanView. [Link]
