If you are thinking about getting married in Gran Canaria, getting a photographer or videographer might be something to consider. There are some companies who arrange weddings in Gran Canaria and, if you book with one of them, the photos and/or video should be part of the package. If not, you might wish to arrange it yourself.
I recently received an email from someone at this company offering wedding photos and videos, although that is the only company I know of specialising in this. I just thought I’d give them a mention though, so feel free to check out their website or let me know if you know of any great wedding photographers or videographers (or ones to avoid!)
