What's a grand Android app for taking photos when you need proper manual control, especially when you're off the beaten track?

Honestly, Open Camera has saved my bacon more times than I can count. As a travel blogger, I need to be able to adjust things like ISO and white balance manually, especially when I'm in places with tricky lighting, like shooting the sunrise over Angkor Wat. This app is brilliant because it gives you all that control, and it doesn't eat up your roaming data like some of the fancier apps. Plus, it's free! I've used it everywhere from the bustling markets of Marrakech to the quiet beaches of Bali, and it always works a treat. It's a proper useful tool for anyone who wants to take their phone photography to the next level without spending a fortune. Honestly, I'd be lost without it on my travels – it's just sorted me out time and time again.
