I went there 2 years ago to do my first underwater photography class with Tim Ho, which was great and can only be recommended. They are set up to cater to us underwater photographers and both Rina and Wayne (the Jonses 😜) are both top-notch photographers. Anilao is mainly known for its rich macro environment, but few know that there is quite a bit of wide-angle to be done there too - well less the big pelagic fish unless you include some of those divers into your shot 😜. One of the things I tried 2 years ago was blackwater diving which I wanted to try but didn't know whether I'd like it or not - well suffice to say that I got hooked and after trying it went out every evening. I usually get a dive guide for myself, but actually wouldn't have an issue sharing one as well as there aren't any fun divers on any of the dives you'd do.
The accommodation is basic, but clean and has lots of space to deal with your camera gear in the room. There is also a dedicated camera close to the dining area and every guest gets their spot. They have everything you need to set up your gear and are very generous to lend you some gear for the time you are there if something breaks or doesn't work as well or if you just want to try something out. The guides I had have been very knowledgeable not just in spotting interesting critters but also critters so they can be photographed. Some of them take photos as well and will correct your position or help you with getting a better vantage point.
I went back there last year and will go back there in May as my first stop - I like it that much.
The cost to dive (you typically pay for room and food as well as your day dives) is very reasonable.
I can only speak very highly of them, as all the staff are super friendly and Rina is the best - top efficient, manages the place as I haven't seen in many places.
I can only recommend this place.
