The usual CBD skyline... first try at stitching.

erwinx · 2nd February 2004

I was in the Marina area looking for birds but the weather turned bad. I decided to take the usual skyline shot because i was inspired to try and stitch 2 vertical shots together (i didn't have an L bracket so the rotation is imperfect and had to be corrected)

apart from that, i found that i had a problem with the sky colour. despite shooting in raw and converting at a preset white balance, i found that the sky colour for the 2 shots were different at the overlapping points. Tried to do blending to make it less obtrusive. Wonder if its a raw converter issue or something else.

advice from those more experienced in pictures stitching welcome

Was your camera in aperture/shutter priority? Your meter may have used two different settings for the two shots causing a shift in colours. One way to avoid this is meter first and switch to manual and take the shots as fast as you can especially for sunset scenes..every minute the sky changes!

Difference in brightest and colour may also be due to vignetting. You can try stopping down the aperture or use photoshop to correct for radial luminence.

Also make sure you're not using a polariser.
