From The Studio, Dec. iqod. — " Mr. Worsley-Benison's 

 recent additions to his ' Westby' series of photographs worthily 

 sustain the h'gh reputation he enjoys. The sea in its ever-changing 

 aspects has never been more faithfully or more forcibly recorded 

 than in the examples he has lately submitted to us. To the 

 marine painter they are of special interest and value." 



The Royal Societies' Ladies' Conversazione : From The 

 Times Report. — " Mr. Worsley-Benison's series of seascape 

 photographs, enlargements in Carbon, were magnificent examples 

 of photographic art." 



The Art Journal. — " It would be difficult to praise too highly 

 the success with which the effect of moving, heaving water has 

 been rendered in the superb composition ' Roll on, thou deep and 

 dark blue Ocean, roll ! ' or the beauty of the sweeping lines of the 

 white sea horses, 50 transient, so momentary, yet thus permanently 



recorded Mr. Worsley-Benison's sea compositions are 



triumphs of artistic arrangement." 



Extract from Mr. Gleeson White's Paper, " The Sea, as Mr. 

 Worsley-Benison Photographs it," in The Photogram. — " To 

 confess that one is entirely captivated by the literal truth of Mr. 

 Worsley-Benison's really beautiful work is perhaps in a way 

 the finest compliment you could pay him. To own how admirably 

 be has chosen the spot to pitch his camera, and the moment to 

 expose his plate : to discuss the admirable development of his 

 pictures, those harmonious skies and accessories, their artistic 

 ' placing ' within a given space, seems almost impertinent after 

 owning he has made criticism appear secondary by the sheer beauty 

 of truth."
