Some of your DOF's on the pictures are really narrow. You can increase this by increasing your fstop [if tripodded], moving further away and decreasing your FOV. That is, assuming you're on a DLSR.
you can change your f-stop on most point and shoot cameras also.

Very true, I recently found the exif data on phone shots, its fun to see what it does automatically.
I chose f/4.0 for the DOF effect 
and partly because of the dark scene in the room, otherwise at F8-F11, the pics were becoming quite blurry. These pics are not going into a data-sheet 
But I like the sharp pics that you have posted. What gear did you use? a tripod, a macro lens?

What gear did you use? a tripod, a macro lens? Tripod, huge (150cm3) light tent, 1.3KW of lighting and a 50mm prime [macro'ish] lens. Not yet tried the new lights yet though, will probably be on the HashCoins Ares.

How do I lower the draw on electricity and decrease my hashrate to much lower? At least until the bitcoin price changes. Thanks.
How much power do you want to draw on the wall?
Here's a voltage / Power draw table from Syke's review https://bitcointalksearch.org/topic/review-10-spondoolies-sp20-tortured-896913
Code:
Voltage W@wall GH/s
.65 710 1240
.70 1005 1468
.75 1110 1520
.79 1150 1534

do your settings on the settings page
use 0.625
on all 4
use 0.63 for max
use 130 for all four watts
this miner does around 1080gh at 520 watts
cool temps lower power

I will order this fan for pull, and they also accept bitcoins:

It's an 8krpm 92mm fan, might be super noisy. I have a 6krpm 80mm fan, and it's quite a bit noisy. http://www.frozencpu.com/products/7868/fan-483/Delta_92mm_x_38mm_Super_High-Speed_Fan_-_17503_CFM_PFB0912DHE.html?tl=g36c15s700#blank

After reversing the fan direction, I also applied tape over the top row holes, since these top-row holes are simply passing through the outside cold air (can be verified with an IR-thermo)
Reversing the fan, allows easy access to the power-sockets, RJ45, and the status LED.

Has anyone tried reversing / inverting the fan?
I tried it yesterday, and the temps are a bit lower than when the fan was facing the other way round. The intake side is outside my window, with the fan pulling in cold air and pushing hot air inside the house.

would be easy to pull in cold air that way. let us know if it keeps working for you.
Three days with the fan direction reversed and no problems yet. It also helps reduce the fan noise in the room, since the fan side is now on the window sill, instead of inside the room.

that's interesting, I pulled my (at-home) SP20 inside by a few inches due to the fact that the cabling could have been exposed to the elements (rain, snow etc) - inverting the fan would help me a lot, especially if your lower temps are persistent.

I found a way to change the fan speed to whatever you want. You can edit the html ..
The changes to /var/WWW folder (where you edit the HTML) shouldn't be persistent after reboot.
I was not speaking about the settings persistence .. but about your php/html chanages which "dissapear" after reboot.
