Subject: Losing your EXIF data

Something to keep in mind when using the save for web option in Photoshop and Paintshop Pro. When you save via this method, your file loses the EXIF data. This data can be a great reference/resource to other photographers, as it contains the setting and details used (by your camera) at the time the photo was taken.

You can use a freeware program like
Opanda EXIF viewer
in either Firefox or Internet Explorer to access this information using a right mouse click over a given image as in the example provided.

Thank you Joe. I did not know that it got lost when you save it for web. Im getting me some Opanda for sure. #:O)

How come we say 'It's colder than hell outside' when isn't it realistically always colder than hell since hell is supposed to be fire and brimstone?

Sometimes you want to lose it! : ) At least on the net.

For the net I don't care to have the exif data avail. But it always remains with my originals. That is a cool feature for the browser though. One other way is to save the image and view exif data in Photoshop. I don't think you can in PSP.You do get some info, if it has been written in I think.

While working in PSP, a copy saved in PSP or JPG will have the exif. A copy in Photoshop will not keep the data. I will have to check to see which files retain exif when saved through the "jpg optimizer" for web usage. I always keep an original on hand(untouched except to copy) to be sure exif is available to me after manipulations of the copy. Of course, I keep an original anyway..exif or not. I once mentioned to a distant friend(Russian man) about the camera used for the photo...surprised him! He did not know the exif came with his jpg.

Saving with the PSP Jpg optimizer(>export>jpg optimizer) for web does indeed delete exif. I saw no options to save the data.

Thanks for the tip. I didn't know that, but I don't know much. I may download that software...looks cool. I would like to know all the exif info for this shot, lens, and your conditions for your beautiful photo here. :-)


TomDart ( ) posted Sun, 11 December 2005 at 9:22 PM

I stand very, very corrected! PSP allows saving exif in the export jpg optimizer if in "standard format", standard one line at a time display according to help files. There is a check box for saving exif. I have not noticed or used that check box before tonight. (it pays to use the stuff and not rely on human ram). : )

I can totally understand the reasoning behind NOT wanting this info posted to the net! Its kinda like an image fingerprint (in a sense) and why give others (those that steal images and try to say that they're theirs), MORE than the already get! I hear ya! I do! I've taken to saving my images with medium or lower jpeg compression and no longer will post anything bigger than 800 x 600 and that usually includes the frame! I still keep ALL my originals for safe keeping! The Opanda software works with with MS Windows as well! Once installed...just go to a image file and right click! It will be on the option menu that pops up!

Photoshop strips the EXIF data to make the jpeg smaller for the web. You can Save As a jpeg and keep the data.


thundering1 ( ) posted Sun, 11 December 2005 at 10:01 PM

I realize I'm going to get shot for saying this, but unless there's something extreme about the image (had to use 1/2000th sec shutter speed to freeze everything in the frame, used a 10 minute exposure for a night shot to be properly exposed at f32, etc.), I NEVER look at the shooting data. Never saw the point, really. Reason being, if you wanted to duplicate the shot, even if you went to the exact location, used the exact same camera/lens combo, your settings would be different because you'll NEVER get the exact same quality of light twice. It will always be a little more hazy, sunny, overcast, generally cloudy, etc. The shooting data may give you a general idea, but you're going to have to tweak YOUR exposure anyway. And if saving for the web, or as another format entirely (you're saving a different version in the first place - not changing the original), I never cared about my EXIF data being there since I'll have it in my originals. If I WANT someone to know what I did to get the shot, I'll tell them.


L8RDAZE ( ) posted Sun, 11 December 2005 at 10:27 PM

Back in the day, some film photographers would carry around a notepad to record the settings they used, so they could be referenced later or they could compare/share them with others! EXIF data is no different. There are some that may actually find this info useful...other may not! This forum is for ALL levels...beginner to advanced...so if this helps even 1 person... then thats great in my book!






thundering1 ( ) posted Mon, 12 December 2005 at 7:22 AM

Oh I know know about the notebooks (not just some photographers, MOST did) - used to carry one myself. Look in just about every photo publication and you'll see their shoting data - it's made that much easier with the EXIF data. But look at most of the data and you'll read something like 1/125th at f8 - nothing Earth-shattering there. 9 times outta 10 it's simple data like that. Not something like (in broad daylight) setting their camera to ASA 1000, shooting 1/4000 at f22 so they could not only freeze everything in sight, but have a tremendously deep focus. Or using ASA 50, and shooting 1/4th sec at f16 so they could get the water motion-blurred yet just slow enough so the greenery doesn't obviously motion-blur in the mild wind on an overcast day. Learn, learn, learn! I am ALL for sharing info, but people are now able to publish their shooting data and sound professional when they're using a digital point&shoot - when if you and I went out there with our DSLRs we wouldn't have nearly the same data with our shots. And how many people shoot manually these days? We live in a world where just about everything is in "Program" mode (or the Canon "green box") where the camera completely takes over, or Aperture Priority or Shutter Priority - I'm not knocking these because they're truly helpful, but 1/2 of the shooting equation is left to the camera, not a purposeful choice on the shooter's behalf because of something they specifically wanted to achieve - unless they NOTE that they specificaly wanted THIS F-stop or THIS shutter speed to acheive THIS effect. And... as you may have guessed... this could ONLY be shared in the image's description - not the EXIF data - which is why I don't care if it's shared in the data of an image if someone right clicks on my post and chooses "Save Picture As" to their hard drive.

All good points. I didn't realize Save For Web stripped away the exif data, but I'm not unhappy about it. If anyone wants to know, I'd be happy to tell them. For teaching purposes, I'd leave it attached (if I remember), otherwise, I don't see why I'd want to share that info.

With Photoshop file viewer and Bridge you can add copyright info to the EXIF that for me is a good reason to leave it there. I know just about anyone can then remove it, but people that d/l images and send it to friends etc can also send your copyright info, this could (and has) result in someone then being able to contact you for usage rights, this has happened to me recently, resulting in one of my images being used on the front of a 2006 calendar.

I only remove EXIF if file size is an issue (some upload sites restrict it to silly amounts)

I dont have a problem with people seeing my shooting data, as mentioned every situation is different, therefore reproducing the results is unlikely.
"And how many people shoot manually these days?" I do, not every shot, but the majority.

Hmmm....i installed that Opanda software...and windows couldnt recognize one single image-file after that. All files, wheter they were jpegs, tiffs, psds or whatever showed up as unrecognizeable files for me. I had to re-associate all the files to their original applications again. Ah well...that was done in a jiffy (is that what you english-spoken folks call it?)....just thought i would share though incase anyone else runs into the same "problem". #:O)

How come we say 'It's colder than hell outside' when isn't it realistically always colder than hell since hell is supposed to be fire and brimstone?

My exif data states my full name and the cam used!...down to the body serial number!...no qualms there!



Nameless_Wildness ( ) posted Tue, 13 December 2005 at 3:10 PM

file_311118.jpg

not showing the serial number!!!!...reasons obvious!!!...but heres the exif on one of my RAWS.



Nameless_Wildness ( ) posted Tue, 13 December 2005 at 3:16 PM

The exif data is pointless to anyone! All it shows is the data recorded FOR THAT scene, be it, auto, aperture, shutter , auto pri conditions etc etc...no good anyone setting up their own cam with these settings as it will prove pointless!...each scene will bring upon its own data....which brings me a point in where pple ask for the exif data!!!!!!!!!!!



LostPatrol ( ) posted Tue, 13 December 2005 at 3:28 PM · edited Tue, 13 December 2005 at 3:29 PM

I think that it maybe stems from photo albums such as photobase that include shooting data as an option with images, dont see much point either on knowing the shooting settings, maybe shutter speed could be useful for flowing water scenes, but that still depends on the water velocity for the end effect.

5D Exif, look forward to getting my hands on one of those babies!

As someone who does astrophotography, the EXIF data is very important. If I see an image of a DSO that I want to try for, I can look at the data (most also post their settings and processing info) and see if I can aim for the same settings or use them as a beginning. I may not be able to recreate the exact same image, but with the data, I have a partial chance on at least getting something workable to process. :-) -Christine
