Ghastly sort of camera captured bishop (7)
I believe the answer is:
macabre
'ghastly' is the definition.
(I know that ghastly can be written as macabre)
'sort of camera captured bishop' is the wordplay.
'sort of' is an anagram indicator.
'captured' is an insertion indicator.
'bishop' becomes 'B' (abbreviation for bishop in chess).
'camera' with letters rearranged gives 'macare'.
'macare' enclosing 'b' is 'MACABRE'.
(Other definitions for macabre that I've seen before include "Shockingly horrible" , "Ghastly, gruesome" , "Gruesome, suggesting death" , "Dark and disturbing" , "gruesome result" .)
