Getting quality results on the Aero takes a little bit of practice as the Speed Graphic handles poorly when compared to modern cameras. (in my opinion, at least). I had to take it out for a spin several times before I got the hang of it and stopped making mistakes.
First up, we have to load our film into the film holders, one on each side. To keep it brief, a notch in the top right corner tells you that the emulsion is facing you. The emulsion side needs to face outwards towards the subject from the film holder when the dark slide is removed. Tip: Open and close a film holder in daylight to understand how it works, and what features it has to help you work with it in the dark or a dark-bag.
Get a sturdy tripod. The bigger the better. Just to take the weight and dampen any unwanted vibrations. The Ektar and the Graphic are both heavy in their own right, and together they are quite unwieldy. To add to the difficulty, the Kalart rangefinder and range guide on the rail are calibrated for the Kodak 127 / 4.7 that usually accompanies the camera, so your only choice is to use a tripod and the ground glass for accurate focusing.
