The location is Plymouth (Devonport) I think, with Garland passing the entrance to No. 4 Basin. The same cranes can be seen from further south in the background of an early war photo of Acasta, the second on this page: http://www.glarac.co.uk/node/2276
This clearer Polish photo does in fact confirm that glare had washed out the tone of some of the camouflage in the Australian photo. There were 3 tones of paint on Garland, dark to light A, B, & C. If you look at Ravenís drawing on page 8 of WP1 he has the majority of the hull, including under the arch, light tone C. He then has the pattern of dark tone A. He has medium tone B limited to 3 panels, all from the bridge forward. This is how it appears in the Australian photo.
In this Polish photo most of the hull is painted the middle tone B. The pattern is tone A and there are just two patches of the light grey tone C, one at the bow and one at the stern. Under the arch is medium tone B not the light(est) grey tone C. This is also how Garlandís hull is depicted in another (private) image I have been sent.
(I think the colourised image can safely be discounted.)
