panoramic photographs
- Keep an eye on the edges
The edges of the image frame
are the most critical part of the
source picture. It is important to
make sure that moving details
such as cars, or pedestrians,
are kept out of these areas.
Objects that appear in the edge
of one frame and not the next
cause problems for the stitching
program and may need to be
removed or repaired later with
other tools like the Clone Stamp.
Though not strictly a photographic technique, timing is very important when photographing your
sequence of images. The best approach to solving this moving object problem is to wait until the
subjects have moved through the frame before capturing the image. A similar solution can be
used when photographing in changing lighting conditions. For instance, if you start to capture a
sequence of images in full sunshine only to fi nd that halfway through a rouge cloud shadows the
scene, then it is best to wait until the sun is shining again before recommencing the capture.
Alternatively if you are photographing in a busy street and there looks to be no reprieve from the
hosts moving through your frame then capturing two of more photos for each source image will
give you plenty of scope when it comes time to stitch.
Try to time your exposures so that you limit subject
changes at the edges of your picturesAdvantages of Shooting RAW
~ You get to use the full tonal and color range that was captured by the camera.
~ You can remove many of the fi le processing decisions from the camera to the desktop
where more time and care can be taken in their execution. This includes:- White balance changes
- Highlight, shadow and midtone adjustments
- Applying sharpness
- Manipulating saturation
- Color mode (sRGB, Adobe RGB etc.) switches
~ You can make image data changes such as a switching white balance settings without
image loss. This is not possible with non-RAW formats as the white balance results are
fi xed in the processed fi le.
Disadvantages of Shooting RAW
~ Bigger fi le sizes to store on you camera’s memory card.
~ Having to process the images before use back at the desktop.
~ Needing specialist RAW processing software in addition to your favourite image
editing package.
