Hello Oceania, Many of these filters look closely related...

The 4 "Skylight" filters (#1,5,6,7) are essentially UV filters that filter UV from the light coming into the lens as well as protect your lens from scratches, dust, saltwater and so on.

The 2 "UV" filters (#8,9) are again, nearly the same as skylight filters with different brand names and method of production.

The "Haze" filter (#2) is another UV/Skylight styled filter with a slightly different color to it and will block out a different chunk of the light as the other UV/Skylight ones, probably more of it to.

The two Tiffen filters (#3,4) are as follows.
81A - Balances daylight film for use with 3400ºK lamps.
62M 85 - This was the tough one, All i can find is a 85 series by Tiffen which is used to convert type A film to daylight. Nothing on the 62M though.

#10 is a Circular Polarizing filter which will block out some light, reduce reflections and of course protect your lens. Think of it as a polarized sunglass for your SLR's lens.

I would keep all of them, the only ones you realy dont need are the ones for Film camera's (IE; #3,4) and even with several UV/Skylight/Haze filters they all will provide a certain aspect to be gained or lost and you should play with these and see what gets the coolest affect in a certain scene. Carry as many as you can!

As for how to protect them I have used a few different methods. Primarily when i am not on trips and not counting ounces and grams i use a small Tupperware container to stack them in, fitting 5 or so in each. When i go on trips i sometimes just wrap them in tissues or use toilet paper. If you can, get some cheap microfiber fabric and sew small circular pouches to protect them as they are light and don't leave a residue of little fluffs on the lens like toilet paper does. They are made commercially but are costly and its far cheaper to just toss them in, or make small microfiber "gloves" for them.

Hope this helps,
