android forums would be your best help..
rather than in TMO
and especially in an unrelated thread...
and even more especially in an off topic thread...

I know that if you don't have gapps installed ...so no play store ...
then your options are severely restricted.
Only place you may ...and I say "MAY" ...find anything close to what you want...
and I say "close" ...
since there may be a camera apps....
but I do not know if they will fill your specific demand...
is downloading the fdroid apk
fdroid is your best bet...
if you need an app but cannot use the play store.

whether there is a camera app there that fits your need...
Is another matter.

Now...
back to our regularly scheduled programming...
