Are there guide values for the SNR of different image types?
As a very basic approach, the following values can be used as a first estimation of the SNR of different image types:
Bad quality confocal image: SNR = 10
Noisy confocal image: SNR = 20
Good quality confocal image: SNR = 30-60
Good quality widefield image: SNR > 40
If the image noise is clearly amplified after the restoration then the SNR value provided to the deconvolution algorithm was too high. On the contrary, if the restored image looks too smooth then the SNR value was too low. In both cases, please proceed to restore the raw data again with an adapted SNR value.
