My first camera was a Canon D30. It shot sRGB files
and produced 3.2 or something like that megapixel file sizes. As if
file size really mattered.
I used a 50MM Canon 1.4 lens, and a Nikon 105MM lens that I would
use by adding an adapter I purchased for $80.00 from some guy in New
York, off Ebay. Hey, crude, but it worked!
Here's a few samples that I just dug up, from back in 2001. I shot
A LOT of babies, families and weddings with that camera, until it
drowned in a lake, after I accidentally dropped it in front of 20
people all posed up on a dock.
I have hundreds and hundreds of sessions just like these examples
below. I shot with my little dinky D30 for almost 9 months, producing
thousands of digital exposure for weddings, families and baby and
child portraits. It made us well over $200,000.00 in sales.

Above: 2001 These folks ordered a ton. They have a
20" x 30" wall print. They own several restaurants in our
city, and even let me display on their walls. 3.2 MP file, JPEG.

Above: 2001 Typical of many of the baby sessions I
create every year. This baby is 2 days old, dad and mom, both surgeons
with specialties. Repeat clients, excellent referrals. They have four
kids. Above is the original, from the camera. I have produced 30"
wall hangings from this file. 3.2 MP file, JPEG.

Above: 2001 These folks ordered a ton as well. They
have several 20" x 30" wall prints and various other sizes.
The couple on the right, both family docs, shot their wedding about
a month after this shoot, and currently shooting their second baby,
who is on our babies first year wall panel program.
They received a free session for booking their wedding with me.
The man on the left, surgeon, the parents in the middle, both retired
after a long successful career as an exec.
