If
you use any of our ordering software we
recommend that you do not resize your files,
simply send them as they are, see below
for exceptions. We prefer sRGB and we
accept other color spaces such as Adobe
RGB. We will color correct and resize your
files as needed.
If you would like to color correct your own files
please use our Economy Services and see guidelines
in color
management.
Following are further particulars:
Bay ROES will only accept jpegs.
Only one file is necessary per image, even
if multiple print sizes are ordered from
that image. If you have done Photoshop work
please discard any extra channels and be sure
to save using highest quality jpeg settings.
We prefer that you leave your files at the original
file size but in some cases, where those files
are much larger than what is being printed, i.e.
Proofbooks and proofs, some people like to reduce
their file sizes for quicker uploads. If nonstandard
print sizes are needed, canvas the file in Photoshop® and
then order a proportional print size, or
use the "Fit" option in Bay ROES. Keep
in mind that our printer will resize each
print at the optimum resolution for that
size. Unless ordered via ROES (cropping and
sizing is done in ROES), prints with an aspect
ratio different from file ordered will automatically
be cropped from the center. Calibration kits
with instructions are available free of charge
from Customer Service. We provide color corrections
to your files unless you indicate otherwise by
using our Economy Service.
Digital Cameras
measure their resolution in pixels. These
pixels are NOT measured per inch, but are
a total count of how many pixels were used
to capture the entire image. If you take
a digital photo at 1600x1200 pixels, the
total pixel count of the captured image will
be 1,920,000 pixels. Whether you print this
1600x1200 image as a 8”x10” photo
or an 16”x20” photo,
the original file will still have 1,920,000 pixels.
Photos
intended for print should be taken at the highest
[pixel] resolution possible for the best print
quality.
Lower resolution photos printed at larger sizes
may stretch the pixels beyond the point where
they look clear and sharp however it is amazing how large you can print
a small file that is sharp and properly exposed. View your files at 100%
in an image application such as Photoshop, this will give you an excellent
representation of how the file will print.

*File sizes are full image sizes not compressed
jpeg size. In other words your jpeg size will be
smaller than the file sizes listed above. To view
and display the file sizes listed above, open the
jpeg in an image application such as Photoshop
to check the Image Size.
A histogram is a very
powerful measuring tool that graphically
represents the data within an image file.
Having an understanding of a histogram will
enhance your camera’s
exposure which determines the pixel values
of your image. Having properly exposed images
is the #1 thing to improve color management. Understanding
