Hi Greg & Rob,
Thank you for your quick responses. I've taken the photos on a tripod under
an artificial sky to minimise errors, but from what you are saying there's
nothing I can do to create a camera response curve.
Thank you for all your help.
Kind regards,
Peony

Well, Photosphere is supposed to handle some camera motion, but if you're
shooting from your bicycle....

Haha Greg, isn't another likely problem camera movement between
exposures?

Hi Peony,
The likely problem is that your smart phone is too smart! Most phone
cameras play tricks with the response curve, white balance, and other
capture characteristics that undermine any attempt to get a consistent
HDR result. No phone cameras I know allow you a true "manual mode" that
disables such behavior, so they aren't really suited to HDR capture.
Best,

Dear all,
I am trying to create HDRIs using an Android Smartphone. I have taken
six photos ranging from –3 to +3 and have tried to fuse these in
Photosphere, however I am getting a “cannot solve for response function”
message. Does anyone know how I can create a response curve or what I
am missing to create the response curve? I can create a HDR image using
the generic response curve, but for my thesis I would need all the HDRIs
to be as accurate as possible.
Thank you for your time.
Kind regards,
Peony
