My wife's hobby is marine aquariums. Mine is photography. I currently have 3 cameras, she has 3 fish tanks. I have a closet full of lights, meters, tripods, reflectors, bags. She has 2 closets full of pumps, hoses, filters, and chemicals.
I spend hours adjusting images in Photoshop. She spends hours adjusting corals in the tanks. She takes a hunk of coral out, whacks off a piece (called a "frag") and puts it somewhere else. She has a big "turkey baster" device she uses to blow junk off things. It's her version of clone and heal.
I worry about white balance. She has 8 different kinds of lights on timers that can change the colors in the tanks. I spend a lot of money, she spends more. I don't sell anything, she sells frags for $25 to $75 each. She took in $1,200 at a recent weekend swap meet.
I have photography forums on the net. She has more. Much more. From looking over her shoulder, I'd say the serious acquarium hobby has 3 to 5 times the number players as the photography hobby. UPS and FedEX bring me something 3 or 4 times a year. They bring her something 3 or 4 times a month.
Sometimes I show her some photos and ask her which are best. She shrugs and says "Meh, they all look about the same to me." Except with pictures of the grandkids. Then she has strong opinions, none of which are based on the things we photographers worry about. An overexposed, blurry, yellow tinged shot of a 4 year old running out of frame can easily be her favorite.
After spending hours rearranging a tank, she asks me what I think. I say, "Meh, looks the same to me. What did you change." I get in a lot of trouble that way.
