Exif data

July 16th, 2015
Not sure if this has been brought up before but I can't seem to get the search tool to work for me so thought I'd start this new thread.

Can anyone explain to me why on some photos we can see what camera was used to take the photo but on others that info doesn't appear, even within the "exif" area?

I'm thinking it has to do with how the image has been processed but can't put my finger on what exactly causes the camera info to be stripped out of some processed photos but not of others.

@gardencat You're absolutely right - it depends on the processing program. Some strip the Exif data off for whatever reason.

Also - the new version of Lightroom, which lots of us are using, has somehow changed how the camera type info is exported... So the exif info shows up on 365, but the camera type does not

How you process makes a difference too - in photoshop if you copy to a new image, the exif data is lost. Or any of the automated photomerging processes (panorama, hdr, etc)

It's still a bit of a mystery to me. I use Photoshop and Bridge and sometimes Perfect Photo 9 but not Lightroom so I can't speak to that. I have some images that are heavily mucked around and still retain the camera info.
This one is an HDR image, shot with an IR filter and processed in Photoshop to bring out false colours, then had a Holga camera effect action applied. Yet it still carries the camera model info. http://365project.org/gardencat/365/2015-01-06
Interesting, come to think of it that although this is actually a combination of three pictures, taken with different shutter speeds it lists a shutter speed (which seems to be a rough average of the three actual shutter speeds).

I use a Watermark program that strips the camera model data which irritates me, but for 365, I do not use the watermark program. I just use it for when I upload photos to Facebook. So agree that editing programs do strip or change exit. I use Corel Paintshop Pro and any editing I do, the program will retain the exit info after converting from raw to jpg. I also stamp my info using the comment feature in my Nikon.

Pickmonkey used to always leave the data on but I noticed today when I edited a shot in it, the data was missing. I wonder why?
