What is the easiest way to adjust EXIF timestamps on photos from multiple cameras in Windows Vista?
Scenario: Several people go on holiday together, armed with digital cameras, and snap away. Some people remembered to adjust their camera clocks to local time, some left them at their home time, some left them at local time of the country they were born in, and some left their cameras on factory time. The Problem: Timestamps in the EXI...
How do you place EXIF tags into a JPG, having the raw jpeg buffer in C++?
I am having a bit of a problem. I get a RAW char* buffer from a camera and I need to add this tags before I can save it to disk. Writing the file to disk and reading it back again is not an option, as this will happen thousands of times.

I am writing a photo gallery/sharing website and want to (1) write EXIF data to the JPEGs stored on server, and (2) strip that EXIF data prior to writing to the output stream for display.

In order to keep the file sizes down, we strip all exif data from the source using mogrify: mogrify -strip image.jpg What we'd like to be able to do is to insert some basic exif data (Copyright Initrode, etc) back onto this new "clean" image, but I can't see...

Resize image in Python without losing EXIF data
I need to resize jpg images with Python without losing the original image's EXIF data (metadata about date taken, camera model etc.). All google searches about python and images point to the PIL library which I'm currently using, but doesn't seem to be able to retain the metadata.

UIImagePickerController does not deliver geo tag data
When I use UIImagePickerController to select a photo, either from the Camera Roll or the Photo Library, the image that gets returned to me in the method 'didFinishPickingImage' does not contain the exif data for latitude and longitude.

How to save an EXIF format image file in .NET 3.5
I want to save an image in EXIF format using System.Drawing.Image.Save or a similar method in a C# application using .NET framework v3.5. The MSDN documentation lists EXIF as an option for ImageFormat. However, it does not seem to be supported - at least not without some configuration unknown to me. When I enumerate the built-in encode...

Exiv2 in 64-bit (or another EXIF writer)
I need a non-destructive way of adding EXIF tags to jpeg images from .NET code. So far I have found Exiv2 and the .NET wrapper Exiv2net that works well when adding or updating tags. However, my code needs to run on a 64-bit machine (and compiled for 64-bit due to other reasons) and it seems to me that the Exiv2 code only compiles in 32-b...
Which EXIF tag to store keyword/tag for a photo?
I am developing a photo gallery which will read/write EXIF tags. I will put photo title in the EXIF tag DocumentName and description in EXIF tag ImageDescription. I also plan to use the geo-tags.

I have found various code and libraries for editing Exif. But they are only lossless when the image width and height is multiple of 16. I am looking for a library (or even a way to do it myself) to edit just the Exif portion in a JPEG file (or add Exif data if it doesn't exist yet), leaving the other data unmodified.

Is it possible to write or change EXIF data of images saved to iPhone photo library
I would like to add some custom data to an image the user generates in my app, no more than 1kb tops. I could probably hide the data in the image, but I want to do this in a way that will resist resizing but not deliberate deletion of EXIF tags (say, for privacy reasons). Is this possible using the current public SDK 3.0? ...
