I know this is a superficial question, but can someone tell me why in the picture above, the tubes don't appear to be glowing as much as the amp in this pic below ?

I see what look to be green leds, but I'm referring to the orange/blue glow of the tubes themselves. They look much brighter. Is it simply a matter of the photography ? Or because they are different varieties of tubes ? I'm a noob, never owned a tube amp or preamp before, but find them fascinating. I am especially interested in a well built, American product representing a good value such as the AVA ultravalve. TIA

That is my piss poor picture with the Ultravalve under my desk, very dark area. The difference between the amps is both photographic and tube type as you guessed.

A tripod and a long exposure does not always make a good shot of glowing tubes. Of coarse if you "adjust" the bias to 5 times or more it's norm you can get some amazing shots. But that's cheating.
