Photographer's Guide to the Sony DSC-RX100

If you regularly use long exposures, we recommend that you get the Sony RM-VPR1 remote control, which has a slider lock. When the camera’s shutter speed is set to B, the lock will allow you to open the shutter and keep it open with a single press of the remote’s button.

If we do not need this level of performance, we use the noise reduction feature in Adobe Photoshop CS. Although it is not as good as what we can obtain with DxO, it operates faster, works on RAW files, and is superior to the a7 II High ISO NR setting.
