I have a small and simple GUI application which will show EXIF information in JPEG images. It's X-only, and has been tested on 10.1.2 only, but should run just fine on 10.1. I also tested with images from only two cameras so far (Sony 707 and Canon S100).If you want it, it's free at.The guts of the application comes from the 'jhead' command line utility - many thanks to Matthias Wandel, the author, for writing that and making the sources available. In fact the whole app is just 117 lines on top of that.Ali.

If you don’t have iPhoto or PS and find Mac’s built-in EXIF solution limiting, EXIF Viewer is the app for you. It’s a really lightweight utility. It’s a really lightweight utility.
Today's Macintouch has posted a request for OSX image manipulation programs that are EXIF aware. I realize that this utility isn't a manipulation program, but you might wish to let Macintouch know about this utility in any case.Cheers.Aliwrote:I have a small and simple GUI application which will show EXIFinformation in JPEG images.

Binowrote:Hi, Ali!Thank you for useful app!!!Glad you find it useful.FYI, I finally got a chance to download sample images for most of the cameras Phil reviewed and ran them through the app, and other than a glitch with Nikon D1x sample images, they all worked fine.
(D1x images, or at least the ones on Phil's site, seemed to have slightly malformed header. I changed the app to account for this, so now they work.)Anyway, I'll continue to update the app on the webpage as needed and as I get the chance.Ali. Jim Robertsonwrote:Bottom line: would you have time to peek at a few of my JPEGs andsee why the EXIF data seems to be 'missing in action' as far as somany other image handling programs are concerned?A bit more exploration on my part reveals perhaps one clue. When I look at JPEGs that come from my D600 in BBEdit Lite (after changing the filetype to TEXT) the string 'EXIF' is no where to be found. The exposure data is there. Perhaps Juri's Cameraid is just smarter than the other programs when it comes to extracting the data.
If I look at an image taken by a Coolpix 900 that was emailed to me, there is header data that includes the string 'Exif'.-Jim Robertson. Jim Robertsonwrote:I'm struggling to understand iPhoto. I was VERY disappointed todrop a folder of images that I'd brought to the Mac from my OlympusD600 using my USB CameraMate and find that iPhoto seemed unable tofind the EXIF data. I went back and looked at a few of the imagesin Cameraid, and the EXIF data is STILL THERE.
However, now I findthat NO other program but Cameraid seems to be able to find theEXIF data. Not GraphicConverter, not iView Media Pro, not iPhoto,not even your utility designed just to extract the EXIF data.I think this implies the EXIF data has been stripped somehow.I have many folders of JPEGs on my OS 9 partition that Itransferrred to my Mac either directly from myOlympus D600 Camera(using Cameraid) or using a Microtech USB CameraMate. When I openthese photos in Cameraid, stuff that HAS to come from the EXIFheader is displayed (brand of camera, shutter spead and exposuredata, picture date and time). However, if I examine such imagesusing iPhoto, iView Pro, Graphic Converter, or even EXIF Viewer,the only info. That shows up is the Macintosh file date.Perhaps this Cameraid removes the EXIF data and puts it in another database which it knows how to look at?Here's what I am pretty sure is the case with iPhoto is (I verified on 10.1.2):When you import images using iPhoto or ImageCapture, the images come down exactly as they exist in the camera. The EXIF data is preserved, if the camera had it in the first place.If you copy the images from iPhoto by dragging them to Finder or Mail or TextEdit or EXIF Viewer or any other app, the original image is copied over as-is, so the EXIF data is preserved.If you 'Export' images from iPhoto using the 'Export' menu item, the EXIF data might be stripped if you had any transformations on the original image - for instance, rotation, red-eye removal, cropping.
Otherwise if there are no transformations and you export as JPEG, the original is copied as-is, and the EXIF data is still preserved.Now I'm in the market for a new digital camera, and I want to makesure I buy one that will transfer the EXIF data to the Mac. I'mlooking at the Minolta Dimage 7.My experience with the Sony 707 and Canon S100 is that the EXIF data is preserved when you transfer the images to the Mac with either iPhoto or ImageCapture.Do you have any thoughts on this? Would you be able to make moresense of it by examining any of my JPEG files?I can try, but I am no JPEG/EXIF expert. I do have the original command line 'jhead' program which dumps all EXIF tags, that might give a little more clue, but if EXIF Viewer reports no tags except for the file date and size, I think that means the EXIF data has been stripped.By the way, the number of fields in the EXIF data is apparently farmore than what EXIF Viewer captures.
Some of it is incomprehensibleto me. Epson says they put their 'Print Image Matching' data there,for example.Yes, the EXIF spec is full of lots of tags that are not as interesting as the common ones that most apps display.Bottom line: would you have time to peek at a few of my JPEGs andsee why the EXIF data seems to be 'missing in action' as far as somany other image handling programs are concerned?Sure, send one or two over ([email protected]); or instead post a link to them here so others can also comment.Ali. Aliwrote:Sure, send one or two over ([email protected]); or instead post a linkto them here so others can also comment.AliA bit more investigation with a text editor has shown me that NEW images brought in from the D600 using the USB Cameramate (this may not be fair, because there are some driver images for this device that prevent it from triggering Image Capture's launch) keep their original exposure DATE, but your utility can't see the shutter speed/f-stop data. Moreover, the original exposure date/time make it into iPhoto, too.
I think the CAMERA must be part of the problem.I've sent e-mail to Juri. Hopefully he'll tell us if he's 'special-cased' Olympus cameras.I'll let you know what I find out.-Jim Robertson. I've solved my own EXIF mystery. It turns out (Juri Munkki discovered this for me) that the Olympus D600L never records EXIF data in the first place.
Its file format is JFIF. Some of the same information is recorded as text at the beginning of the file, but it's not tagged as EXIF (apparently the EXIF format was standardized more recently than the introduction of that series of Olympus cameras).Cameraid searches image files for both JFIF and EXIF data.
That's why it recognizes the data when the other programs don't.The remaining puzzle for me now is why when I bring in NEW images from the D600 using my USB Cameramate, the files are listed with their acquisition (exposure) date rather than Mac file date.-Jim Robertson. Ali:Thank you for writing the front-end to make this useful EXIF viewing application for OS X.

It works perfectly with images from my Canon PowerShot A20. I was able to read EXIF info from some old pictures that I thought was lost after much post processing.Brilliant! You should register your app with VersionTracker and publicize it a bit more (if you are not worried about more users, more feedback and more pressure to develope it further).Thanks again!EscherAliwrote:I have a small and simple GUI application which will show EXIFinformation in JPEG images.
Every now and again I run into a Mac app that is free but is so good I would pay money to own it. That’s exactly the case with Photos EDIF Editor for the Mac. The app’s name could not be more descriptive. It edits photo EXIF data.If you know the intricacies of digital photography, then you know about EXIF data. Every digital camera stores specific information– metadata– into the image file format. This exchangeable image file format, or data, has been around awhile, and it can be useful.
And it can be edited. Now.If digital cameras (and other devices; EXIF data is not limited to photography) embed data into a file, then why the need to edit? Offhand, I have some experience with this issue. I’ve had cameras go wonky and not record any data, or a camera with a bad battery that embedded wrong information.
I’m sure thieves and criminal entities would prefer some EXIF data be deleted.That’s what does. It edits EXIF data within a single file or multiple files in batches.
Reads & writes EXIF, GPS, IPTC, XMP metadata and more. Supports various common image formats including RAW format. Deletes metadata individually or of selected batch of photos. Sets photo modification/original date-time from EXIF information. Automatically creates back up of the original metadata of the photo when writing.
Flexibility to create Presets of repetitive metadata to speed up processingNot bad for free, right? Take a look.The editor lets you edit EXIF data on multiple photos at the same time, and has a Restore To Original option so whatever you edited can be reversed. Think of it as an EXIF undo.Some EXIF data will vary camera to camera, so the editor can let you create presets to use on multiple devices.
All the data– whether EXIF or iPTC or even XMP–can be viewed in a separate window.Making edits couldn’t be much easier, either. If you can edit a Word document or navigate through a database entry, you can edit EXIF data on your photos.Make the selections you want. Click the Start Process button.There is even an option to set custom time-date stamps and edit GPS information. The easy way. Drag and drop.You can view/edit date-time values as required. In addition, you can drag & drop the marker pin on the map in the application to edit the GPS information. You can also add coordinates and edit GPS to your photos manually.Every EXIF, IPTC, and XMP dataset has a variety of sub-sections and tags you can edit.
Here’s a list of those supported in Photos EXIF Editor.Need to drop in copyright or photographer information into a batch of photos? This is the app that does the deed. Need to change GPS or edit lens data?
