Is it better to deactivate in-camera sharpening if I know that I will use FocalBlade later?
Digital cameras only have limited processing capabilities. They don’t apply sophisticated sharpening methods to avoid blocking the camera for taking another shot. In-camera sharpening can be especially destructive on high-ISO shots that were taken in low light conditions, because in-camera sharpening unnecessarily amplifies the ISO noise. It is generally recommended to switch off in-camera sharpening or at least reduce it to the available minimum. Unfortunately many low-priced digital cameras don’t offer any option for influencing the in-camera sharpening. In such a case you have to live with the result or buy a more expensive camera. Switching off internal sharpening also lets you take more JPG photos with the same memory card, because file sizes of photos without sharpening are much smaller.
