I walk around the neighborhood to exercise. I take pictures of the flowers in the yard, clouds, beaches, sunrises and sunsets. I hope you enjoy the pictures.

Problems with Panorama Mode

You may like my pictures taken in panorama mode. It shows the wider view which can not be achieved by the wide-angle lens without distortion.  However, there will be a vertical line when the camera "sweeps".  It is caused from the exposure changes between sweeps, especially small lighter clouds present in the sky (Apparently, my camera lock iso and/or exposure during the panorama mode).  Any ways to walk around?  I tried to lower exposure -1 EV and other methods without success.  The best way to "reduce" it by putting a dark neutral density filter (3x or higher) to reduce overall light intensities, but it introduces other problems: (1) need to use a tripod for much lower shutter speed and (2) the details of the clouds are reduced drastically.  In the mean time, my little camera does not have a tread to mount the nd filter and I am holding filter in front of the camera to sweep.  It is not easily achieved without reflections between lens and filter, and drew people's attentions with such a strange way to take pictures.

So far, I don't have any "reasonable" solution yet.
