Here's something that surprised me, but which is quite repeatable.
I dropped 3 images onto ICE and it chose to compose them as Rotating Motion, which produced an image 109.2H, 69V extent. I then tried Planar 1 setting, then I set Rotating Motion. This time I got an image 116.3H, 68.2V with quite a different appearance. The first has a bowed horizon, the second is flat.
At 37.5% scale, the first is 3.76 megapixels, and the second is 4.82 megapixels.
I get the same result if I reload the pictures and follow that sequence. It also happens with other image sets.
hi
what's your opinion about ICE? I'm satisfied with it. But what camera motion should I select? And what scale should I select for print and email?
Opinion? good for some things, not for others. It's a tool, and not the only one in my toolbox.
Which camera motion? Ideally the one that matches the way you moved the camera to take the picture, but there's absolutely nothing to stop you from experimenting with others.
What scale for print and email?
Depends entirely on your printer output size needs and the carrying capacity of your email. I typically save at the highest possible level ie 100%, and then use Picasa to export to smaller sizes for use in email or blogs. There are many alternate pieces of software to do this, but be aware that idiosyncrasies of ICE mean that saving at different sizes may mean differently stitched output. So if you're happy with the 100% output, then you're probably safer to use a separate program to create differently sized outputs.
