What can i gift my husband on his 27th bday?

I'm asking this bcoz my hus is an xtraordinary character… His interests are photography and arts… So i really aint gud at that field… So i would like to know what i could give hime on his birthday regarding his interest… Can anyone please give a sugesstion?
P.S.: HE HAS A professional CAMERA which he had recently brought MODEL: NIKON DX D90 + 2 LENS AND AN INDOOR FLASH- NIKON SPEEDLIGHT SB-600… IS THERE NAY OTHER ACESSORIES BESIDE THIS WHICH WILL BE REQUIRED? CAN you MENTION THE RATE ALSO?
.

He's pretty much got all the accessories covered. How about asking him what he wants?

you may find that he would want another lens, depending on what he does and does not have. Maybe a nice tripod, or some studio lights. It matters on what he wants.

The good doctor nailed it.

You can never go wrong with more memory cards, but I suggest if you do buy anything for his camera gear, you buy him a gift card (Visa or AMX) and present it to him over dinner at his favorite restaurant.

If he uses the video feature on his D90, a nice video/motion picture head would do nicely as an addition to his tripod, but again, let him choose.

I did this once for my ex-wife. I cut out some items out of the Victoria's Secret catalog, pasted them in a birthday card and included a VS gift card. I presented it to her over a nice dinner at her favorite sea food restaurant.

The next day, she and her girlfriend spent the most of an afternoon just having fun at the local VS store.

If he has some colleagues who have cameras, he could go with them to a camera store and just enjoy looking at all the possibilities.

You are a wonderful wife.
