I am recently engaged. FI and I are travel nurses so we move every 3-6 months and have everything we need (it fits nicely into our car) so we don't need much. Our mom's have been asking about our registry. They think we will be a difficult couple to buy for (which, I agree, is true). We have decided to ask for a few traditional items to replace some we have that are getting worn, but would like to add more non-traditional items.
We spend a lot of time hiking in national parks and each have a nice DSLR camera body (Nikon J1/J2) that we are learning to use and growing with. We are at a point where a few essentials would go a long way in improving our picture quality. We are thinking of adding a photo editing software (Lightroom), tripods, specialty filters, a new camera bag/backpack as we are outgrowing ours. This doesn't add many more items to our list though. For photographers, what additional items would you list - thinking down the road a little, what other items may we "grow into" as photographers.
