With the Introduction of Valerus V18R2 the privacy masking has been changed from a blank to a pixellated area. Although this looks much nicer it may not mask the image sufficiently for some users. However by placing one or more masks on top of one another it is possible to increase the amount of pixellation and therefore obscure the image more effectively.
To do this, create your first mask and position as required. Then create the second or subsequent mask away from the masked area and resize before moving into position.
Result with 1 mask.
Result with 3 masks.
