For those getting the Avast porthole viewer....I did order the extra orange filter but did not even need to use it for these pics. I did not alter my normal tank lighting in any way so I am not sure if the filter is even worth it (I still haven't tried it.....some say it makes things tooooo orange....others say it works great). If you do get it, it just slips in place and can be removed at any time. I also did zero post editing other than resizing pics and changing them to Jpegs from RAW.
