An estimated 25 million cameras were sold in the US in 2010. Similarly, 81% of US homes own at least one digital camera. That means that roughly 100 million houses in the US already own a digital camera and almost ¼ of those people were buying a new camera. The long and the short of it is that there are a lot of people taking pictures, saving pictures and being photographers.

While @benthepcguy and I consider ourselves photography enthusiasts, @brandonleblanc is a true photographer. We are going to band together this week with @windows and @windowsblog for our Tech Tuesday Live Twitter Chat to share our software tricks (have you tried Photo Fuse in Windows Live Photo Gallery?), the hardware we like (such as the Sony WX5 or NEX-5, which is the camera Brandon and Ben use), and real tips and tricks for lighting, storing, and editing images.

Here are a few things to get you primed for the discussion:

1. You can watermark your photos for a blog post using Windows Live Writer in a few easy steps; learn how here. While not a Windows Live Photo Gallery feature, it is a vital part of Windows Live Writer and essential for those who have blogs and want to protect the images of families and friends that post online. Have additional questions? Ask me during the live chat.
2. Did you know you can make photo books in a few easy steps? Brandon shares tricks and tips via this blog post.
3. Ever been photobombed? It’s now easy to crop out the creepy guy smiling in the background, find out more here or bring your questions to our Live Twitter chat tomorrow.

There is a whole world of things around photography, images and PC-usage but don’t worry - between us all we have the resources to find good answers. Submit your questions below to ensure that they are answered during the chat. See you tomorrow from 12-1pm PT (3-4pm ET); remember to use the #win7tech hashtag or we won’t be able to follow along.

Note we will only be talking about the outlined topic each week and we will not be answering questions outside those topics. Questions for this week may include: How do I use Windows Live Photo Gallery to edit and update pictures? What cameras are compatible with Windows 7 PCs?
