It’s a good idea to Save As after every edit, so that it’s easy to return to a previous step if something goes wrong.

Exposure Settings #

Light exposures #

ISO 1600-3200
Check the exposure that histogram peak is at most about 2/3 way to the right
- Most of the detail is captured at mid-brightness
Don’t use ISO under 1600: (STN) Signal to noise degrades fast.
Increasing ISO above 1600 will not give any advantage. Optimal signal-to-noise ratio is at about ISO 1600-3200.

Resetting the Ikea BEKANT electric desk

Thu, 25 Mar 2021 12:00:00 +0300

If for any reason your BEKANT desk has its legs out of sync, you may notice the desk moves unevenly, doesn’t move up, or doesn’t move at all. What can you do?

Hey rejoice! It’s an easy fix. No need for disassembly.

First make sure the “obvious” things are ok.

The desk is plugged in.
The “key” is in the control box.
There is absolutely nothing blocking the desk from moving down.
(Double check this before moving on)

After checking that there are no obstructions, you can continue. This is important, because the next step will bypass the safety features of the electric motors.
