Back in 2011 I wrote a blog post explaining how to create an OS X Service for stripping keywords from image files. In this post we’ll use the same technique to create a Service for stripping geotags from JPEG images.

As with the keyword stripping service, there are two prerequisites for this action, one is required, one is optional. You absolutely MUST have install EXIFTool installed, and it would be good if you also had Growl installed, but it’s not essential.

I recently gave a talk to Astro2, the Astronomy and Physics Society in NUI Maynooth. The talk focused on taking photos of the heavens without breaking the bank. If you set your expectations appropriately you can shoot the sky with literally any camera. You’ve not going turn your iPhone into the Hubble Space Telescope of course, but you can always get something nice, even if it’s “just” including the Moon and planets into your landscape shots.

The core idea is that you need to take as much control away from the camera’s computer as possible, so that you can push the device right up to it’s limits. To do that you need to understand how your camera works, so the talk starts with a primer on the theory of photography.

The talk is very heavily illustrated with example photos, and each example comes with a description of the settings used when shooting it.

I was asked in the talk to upload the slide deck, so I have (sorry it took so long).

This week’s Insgragram TOS kerfuffle is nothing new. Instagram is not the problem, it’s just the latest symptom of a sick business model that has been allowed to become so dominant as to be almost un-challengeable – services on the web MUST be free, so you MUST give up your privacy and/or your intellectual property rights to enable the service providers profits. If you dare stand up for privacy then you are a greedy idiot who wants something for nothing, and you need to grow up and let the companies make money.

My problem is not that companies want to make profits, it’s their instance on selling our data to do it that I have a problem with. How about this for an idea – why not let people pay for services rather than insisting we all whore out our privacy and intellectual property?
