I have never done two rows of images - so forgive the blondness
I assume you just do 2 rows and the software pics up it's 2 rows??
So I think you've seen enough replies to know there's (almost) no limit.
I think there are a few well publicised Giga-pixel images on the web made from large numbers of stitched source images.
For me I have sometimes used it when I was getting wistful about not having a 50Mp camers, as a way of letting my D300 maybe capture a little more.
If you remember the old NG site, Fred/Alan used this approach quite a lot for several of his forest & landscape images.
For those of you who are more experienced in doing this, I would be interested to know the pros & cons of the different approaches.
Multi-image shots should give us the equivalent of more pixels
- Is this only of use up to (say) 10-15 source files?
- Are we only going to see the benefit when doing really large prints
or online images that people can zoom in/out of ? - Are there any drawbacks?
