What I have tried and have been successful in preparing for Rustic projects is paint the ends of the logs 8 inches longer than the future docking length. Cut timber 5% thicker and wider than the finished board requirements. Wait 2 days for the timber to lose surface moisture, then paint the boards with the selected clear finish that your project will end up with. Two coats for end grain. This way they will SLOWLY shrink as they dry.
Rack out under cover from the sun, well up from the ground, with the worst boards on top, under plastic sheet and tin and keep them weighed straight.
SLOW drying almost eliminates deformities, the boards are protected from dirt, oils, mildew, insects, and humidity changes.
If you are clever and game, you might end up with an excellent face side to preserve as a feature to show the original saw cuts, and already with the first coat only needing a fine sand.
