PANORAMA FROM M43 (E-P1) FILES

(Click for XXXXL version …19MB file …OK, compressed for web use)

I’ve already stated before that files from my E-P1, at its lowest ISO setting, are not a million miles away from those of my Nikon D3 – as was, now sold because of that very fact ! I still use a pair of D200s, which produce fine results for any DSLR- type shooting …weddings/sport … anything where very fast AF is essential for static or moving objects/subjects !

Shooting with my Olympus E-P1 yesterday, in very bright sunlight (yes, I could see what I was doing with that lowly 230k res screen, and from heights & angles I couldn’t easily have achieved with a DSLR), I took six individual shots for this example.

Stitched from these six images, this panoramic could be successfully produced as a huge high-resolution print, with great colour accuracy and sharp detail. Using the E-P1 in this way enables its already great 12.3 MP output to knock at the door of medium-format in terms of quality and image size …but there are caveats :

  • MF offers greater dynamic range, with less shadow noise … although multiple m43 files can get close with careful software usage
  • MF offers smoother output, from that relatively huge sensor …  combined m43 files can approach the look, again with careful setup
  • MF requires a very substantial investment : from c£12k to £25k, plus lenses from around £3k each …m43 is affordable for most
  • MF currently has a relatively low ISO capture range, typically topping-out at 1600
  • MF is hefty & unwieldy to cart around for long

Medium Format has so far been the choice of many high-end published architectural &  fashion photographers – where the commissions are often consistently & suitably lucrative to make the investment in MF worthwhile, and editors are extremely demanding relative to output quality and fine detail.

Continuing from my last post, the relevance here is that the next generation of cameras with a Four-Thirds sensor – the new Panasonics about to be formally announced, and the inevitable Olympus versions that will follow – will also enable very many keen photographers to attain a breathtaking standard of very large output quality … where of course the subject & lighting lend themselves to being photographed with multiple files, to then be stitched.

If you’ve not tried image stitching yet, with your own m43 setup, try three vertical shots – or three horizontals – allowing around 20-30% overlap on each image. These can be stitched in software : PS, Arcsoft (which I use myself), or one of many others out there. These days, this software has been developed to the point where little if any manual intervention is required, even without close attention to tripod use/nodal point etc at time of capture. A final crop is often all that’s needed to complete your own masterpiece.

PS : For optimal quality, whereas these were six very quick, hand-held shots, one should always use a tripod for ultimate quality (don’t forget to turn off the IS !). It’s also then preferable to work from TIFF files (these were o.o.c. jpegs), and to set your camera to manual, to choose optimal aperture & exposure settings. These do all count, none of which I did for the example here. The final large image has also been compressed for web use. But you get the idea ….
