LATIN!

'm trying to title a collection of photographs and want to make sure that the latin is correctly used.

The series is about loneliness and they are night photographs featuring objects that seem to have some holy or otherworldly quality of illumination.

So..

solum luminarium

solitas nocto nvenio

lux lucis solus



1.is it acceptable to use "lux" without "lucis"?
2. also, if I was trying to say "light alone" would the above listing be incorrect?
3. when would one say "solum" as opposed to "solus"?


thank you in advance,
with admiration,
leigh
