First, decide how you are going to use your camera module: on a board which has a standard 2x9 header or on a standard breadboard.

If your microcontroller has a 2x9 header available, that method is strongly preferred! The high speed signals of the camera module can be scrambled even with short lengths of jumper wire on a solderless breadboard.

Using side cutters, snap off two 9-pin sections of headers.

If you are soldering for the 2x9 header then place the pins in the two rows at the edge of the board

If you are soldering for breadboard use then place the pins in the outermost rows, leaving the middle row empty.

Carefully align the headers. You can use tacky clay to hold them in place. Solder just one pin in each row, then check again for alignment. If the pins are poorly aligned, re-heat the solder joint while adjusting it until it is straight. Add flux if needed so that you don't end up with a cold solder joint.

Then, solder the rest of the pins.
