how do you black everything out around your subject in both the burner and the globe picture?
In both cases, it was nighttime. For the burner, I took the picture outside. For the globe picture I turned out the lights. I may have used a black cloth as a background (I think I did) but it's been some time since I took that picture, and I'm not sure about that, but I'm pretty sure I did.
I went to a store with cloth (yardage store?) and found some black material. I tried to get the flattest, blackest material they had.
Generally, I use the black material to mask anything distracting in the background.
COMPOSITION- Very nicely shot. You have some great detail on the flames and the middle part of the burner. I like the blue on the black. I wonder how you could have cropped our done something a little different with where the burner is. I think that it would look a little better not in the center.
BACKGROUND- The black works great with the low light of the blue burner. The hot pixel isn't fun to have.
CAMERA WORK- DOF is good. Sharpness is a little soft. The aperature and shutter speed are great. It's not under or overexposed.
DIGITAL PROCESSING- The post work is good. No artifacts from compression. I wonder if you could have sharpened it a little. Contrast and brightness are good.
MY OPINION- This was my favorite of the burners this week. Sorry about the pixel. I just found out my camera has two. I don't know what to do, if that's under warranty or what. Great job on the shot.
I like this the best of all the blue flame photos submitted. The focal point and the angle really make this photo work for you. The composition is ok, but not as bad as the others
