d70 is digital. 6 megpixels. That is what I still shoot. www.rickcavanugh.com for LOTS of photos with d70 (some are film though)
Film does a better job in some instances with wide angle.
To get a good sun burst, set shutter to 1/200 or faster to catch beams. Expose water next to sunburst to get water color. Use strobes to "paint" subject with light.
Digital sensors do not like the high light levels of the sun and it is typical to get a cyan ball. Film does not do that. It is much harder to get a good sunburst with digital. Many you see are photoshopped in after the fact.
Also, must underwater strobes are not TTL, but TTL only works for macro anyway.
