Sapa and Bac Ha time required

I am super excited about finally getting to northern Vietnam to take lots of photos (Amateur photographer) and am trying to decide how long I need. I have the following rough itinerary and would love some advice - am I giving locations too much / not enough time? Any must do's, especially for photos

Arrive Sat morning head straight to Bac Ha for Can Cau Market and an afternoon hike to a nearby village.

Sunday Bac Ha morning market, head to Lung Phin afterwards. Head to Sapa in the evening

Stay Sapa until Tuesday night visiting the market one morning, Cat Cat and either Ta Van or Ta Phan.

I don't want to pack too much into each day as some down time will also be good.

I also want to know where the best place is to get some of those amaizing rice terrace Photos. I will be arriving last weekend of April so I am hoping my timing is perfect.

Lastly, whats the best way to get between Bac Ha and Sapa.

Thank you to anyone who has any advice
