I've given this a decent bit of thought, and in the unlikely situation that you're living a life with no access to modern materials, you're probably living a pretty busy life. Things you've never thought of, like gathering dry wood, finding potable water, stockpiling food, determining what's edible, constructing shelter and protecting yourself from danger will probably take up almost all your time in your first year, if you make it that long. This is of course very dependent on where you are - in many climates you'll be 24/7 trying to survive, but if you're in a fertile area with good weather, maybe some access to fish, you'll probably have a handful of extra hours here and there for fun projects. Hunter-gatherers in a tropical climate with abundant food, thousands of years of experience and a stable societal structure have around 4 hours per day of free time [0] - you will probably not have those things, so count on much less.
What that means is that your time is the most valuable thing. (And materials, which take lots of time to obtain.) So if you begin to price out the time cost of acquiring all the materials to create a furnace and glass, it'll be enormous. The same goes for a steel axe, or books from wood pulp. In fact, anything from metal is an enormous amount of work, so I'd probably leave it aside.
But that doesn't mean you can't have an axe, or paper, or glass - you simply have to look at what people used to do. Stone axes work fine [1], paper from birch bark is great, and mica makes a decent glass replacement. (If you get lucky, you'll find large mica sheets, which are clear as glass - if you're not, you can attach small ones together, but it won't be clear.) If you're in a cold enough climate, and you survive the winter, ice can be a replacement for glass and a weapon.
As for the camera - no way you'll get a functioning "modern" camera with optics and an aperture and everything. I would simply build a camera obscura and use my birch bark - the biggest technical challenge there is getting a totally dark "room", which could probably be done the simplest by making a dirt hut with a wooden front and a pinhole made of birch bark coated in ash. (The thinner the hole material, the better.) If you had people to trade with, and plenty of time, I suppose it would be possible (if difficult) to make a photosensitive plate that you could use with your pinhole.
