Hi everyone,

My first post on this superb Forum - directed here by Bob who wrote about astrophotography somwhere else on this site (I've got to find my way around here).

Anyway - great to find this macro section, thought you might like to see this effort:
http://img517.imageshack.us/my.php?imag ... ckgjn8.jpg

Used the Canon 100mm macro lens on a 40D and made a mosaic which was stitched together in CS3. Original file is something like 250 Megs but Image Shack has a 1.5Meg limit, so this is massively downsized. However, I am really into putting together BIG image files using mosaics, this includes macro and landscape stuff.

Oh - and I should mention my main photography is deep-sky imaging:

I hope to learn a lot from you guys :D

All the best,
Greg

Hi Greg,

May I offer you a very warm welcome to the CameraLabs forums.

That macro shot is pretty amazing. A nice "film like" quality to the image. 8) As for deep-sky imaging, I think it is us who have a lot to learn from you!

If you are looking for online storage for large files then maybe the Amazon S3 service is a possibility as the maximum file size limit is 5 gigabytes and the total is unlimited. Costs are pretty reasonable, as well. As I use the Firefox browser copying files is just a drag and drop operation using the S3Fox Organizer but if you want to make files public you also have to use it to set the relevant permissions after they have been copied. :idea:

Bob.

Hi Bob,

Thank you for the welcome :D

Also, thank you for the link for storage space - however, I work in a University, I have no cash, I can't pay for space :( Just (half) joking - I'll take a look.

All the best,
Greg

Hi Greg, that's a really nice macro shot - could you let use know why you went for a mosaic? I'm guessing it's unlikely to be for perspective or coverage on a macro, and more likely to maximise your total image resolution...

Hi Gordon,

No - you are right - I could have taken the whole butterfly in a single frame with the 100mm Canon macro lens.

By zooming right in however (1:1) it's almost like looking down a microscope at the subject - big image scale - and of course you now cannot get the whole butterfly/moth in a single frame as you only see a small part of it - hence the mosaic.

The great thing about these macromosaics is that when you have one displayed on the monitor - you can keep zooming in and in - right down to where you can see the individual scales on the wings (which I guess are around 3-5 mincrons in size) - so it really is like looking down a microscope.

Also of course, you can print out massive images :)

All the best,
Greg
