Accelerometers aren’t for saving


I really like EXIF data.

Using the built-in email functionality from an iPhone’s Camera Roll results in an email being sent at a resolution of .5 megapixels (800×600) pixels despite the full resolution being 3.1 megapixels (2048×1536). Since copy/paste was introduced to the OS, the trick to email the full resolution image (or multiple images in the same message or in replies for that matter) is to copy the photo from Camera Roll and paste it into the body of an email.


No matter what orientation you hold an iPhone when taking a photo, the OS displays it “correct”. Any apps that load the photo for post-processing load it correct. And if you use the built-in email functionality or copy/paste into an email, it is displayed correct in the body of the email from the sender’s perspective during creation.

The fun comes on the recipients end. Use the built-in email functionality and the recipient always gets a correct version of the photo. This is likely due to the OS exporting a new version of the file from Camera Roll when emailing it. After all, need to get down to 800×600 pixels some how. Additionally, the image attachment will have a file name of photo.jpg instead of the real name (IMG_0949.jpg, for example).

Copy and paste results are different. If the recipient happens to be a Mac OS X Mail user, those photos appear in the same orientation as the iPhone displays them in the body of the email during creation. Other clients don’t. They display them in the same fashion as traditional, non-accelerometer blessed digital cameras do – that is to say, sideways, upside down, sideways the other way or maybe even correct. Apparently orientation is saved in the EXIF data rather than saving the original file in the correct orientation. The file is instead saved exactly how the CCD captures it.

I never noticed this before as I tend to only see iPhone photos in Mail, iPhoto or on the device itself. Sorry if I’ve sent you a poorly oriented photo in the past.

The right thumb

The Apple orientation is Home button/camera controls on the right which puts the lens in the top left corner from the photographer’s perspective. This happens to be the opposite of how I tend to shoot landscape photos with the phone. Not sure why. Seems like it would be natural to hit the shutter release with the right hand but I think that never worked out for me because using the thumb is awkward no matter what. Holding it the opposite way results in the volume and mute switch being right where my traditional shutter clicking finger is giving it some sort of button to fondle, even it isn’t a useful button in this case. And somehow I always end up with a finger in front of the lens to other way.
