but what if the person is already very close to the lighthouse, and i can't capture the whole view of the lighthouse with the person.
Let's assume that the person might not want to walk near the lens due to laziness?
also straight light house is slanted..
PP and PS aside, i can think of 3 ways. or at least this are the 3 things i would do.
either 1 of them that is.
1. ask the person to move forward. if u are using flash as fill flash, it can only cover up to a certain distance frm the camera, so with the person closer to u, the flash can reach too.
2. shoot at the widest possible. and shoot from a lower angle.
3. if the above fails, u can always tilt the camera in such a way such that u utilise the frame diagonally to achieve max. height. more of a artistic shot too.
with PP/PS, u can try:
1. like what some suggested, superimpose.
2. shoot a series of photos, moving ur camera upwards to capture the person and the lighthouse. then stitch the photos together into a straight pano.
oh, regarding the slanted light house, its due to perspective distortion. since u r shooting upwards, the top of the tower looks slanted towards the top centre. if u position ur light house in the middle, it would look straight. hope u get my point.
or u can use PS to correct the distortion.
