In reply to Ellison123:
Good luck, but it seems a slightly confusing question given that "easy winter walking" and grade 1 gullies are radically different things. As someone who doesn't climb but who goes out a fair bit in winter and occasionally strays into grade 1 territory, I'd reckon that grade 1 gullies equate to hard winter walking. I spend a fair bit of time in what I tend to think of as "grade 0.5" territory, which is pretty much inevitable if doing winter Munro/Corbett stuff and perhaps comes closer to the "easy" requirement, but then again hardly anything is really easy in winter and so much depends on conditions. (You wouldn't get me anywhere near Point Five itself, I hasten to add.)
Also, re Sophie's suggestion about going for smaller things, Beinn Maol Chaluim and Beinn Trilleachan aren't really "half-height hills" - BMC is only seven metres shy of being a Munro, and BT is 840m, both of them with low starts and some rough ground en route. As various people have said, Etive's great, but the basic rule of thumb I grew up with in regard to it is that the lower 400m is almost always pretty rough and unpleasant (wet, tussocky, rocky holes in the ground etc) and it's only when you get above that level that things start to be proper fun. There's not really anything easy there at all - big hills along both sides of the glen right the way down, with rough ground and river issues cropping up as well. In terms of what might fit the bill, one very good winter day I had there was Sgor na h-Ulaidh via the forest track system from Invercharnan and then the col between it and the 750m Meall a'Bhuiridh bump. It's still a full day in winter but easier (and less avalanchy) than from the standard Coe side, and the tracks (assuming they're still in reasonable nick) get you up the first couple of hundred metres straightforwardly. The summit is a tremendous perch and might well be just the thing for your photography.
Be cautious about Stob Dubh /Beinn Ceitlein across the glen - another big (if very fine) brute of a thing and consistently steep - there have been deaths of experienced people on this.
