you probably are, a cheap alternative is simply glGenerateMipmaps
and the average luminance of the scene will be texture2DLod(....., , 1000); just put as many zeroes as you feel like :)
it will sample the highest mipmap level (1px)
works well for me.. unfortunately i dont like bloom, and feel it doesnt add anything to my game except brightness, and problems...
you can't have white textures anymore, for example

note that you can use the same scheme to get lens flare and cheap godrays :)
just a little bit more complex..

has anyone actually used bloom successfully, ever?

this is just a regular photo, with bloom filter, which looks ok
but in a game... bloom ruined my clouds :P
