You might remember days when owning a camera was a big deal and buying a film – a costly affair. Things have changed drastically since then: now we all carry a device or two equipped with a decent camera and click pictures of pretty much everything we see. No wonder we accumulate hundreds of pictures in no time. If you share them with others, it’s likely you would have to do at least some basic editing. Do not waste your time by going through your pictures one by one – download a tool that allows you to tweak your pictures in bulk, you’ll be surprised at how much time and effort it saves you.
