Wow the dye looks really good. Tbh I never knew people put dye in their coolant ... :lol:. Won't it damage your pump or leave traces in your resevoir/blocks over time?
Also, I'm not an expert at photography with point and shoots. But for close-ups, I've noticed that putting the camera in Macro Mode, moving a bit away from the subject and then applying a bit of optical zoom gives much better AF; But you'll need to be more steady.
