There
are several ways to reduce high iso noise from ISO 100,
ISO 200 and ISO 400 Canon G1, G2 and PRO90 IS images. The
trick is to reduce as much noise as possible while keeping
most of detail and sharpness intact. These Photoshop actions
work exclusively with Canon Powershot G1/G2/G3 & PRO90IS
jpeg or raw files.
They were developed to minimize or in some cases completely
erase noise from normal/high images, while maintaining most
detail and sharpness intact. In addition, they run faster
than any other noise reduction currently available. (Compatible
with Photoshop's batch mode).
All
G-ISOR actions are compatible with Photoshop 5, 5.5, 6,
7 or higher (PC and MAC). Not compatible
with PhotoshopLE and Elements.
*I
was notified that many S30 and S40 are getting great results
with the G-ISOR action as well. I have not tested the action
on these cameras though.
| All
images were taken from the same location with
a tripod and self-timer. No manipulation was
made to the images prior to performing the actions.
These samples are crops from the 100% image.
Pictures were taken with a Canon G2 and tested
with Canon G1 and PRO90IS for compatibility.Here

images portrait a substantial amount of noise. For
that reason, some photographers shy away from using
it. When running the new G-ISOR 400 action,
you can rescue those ISO 400 shots, and produce
professional quality images.

useable and produce professional quality images
at this iso sensitivity.

already provide relatively clean images, with minimal
amounts of noise when shot in normal light conditions.
However, when shooting in low light there is a possibility
that ISO 100 images could have a noticeable amount
of noise in the shadows. This smart action will ONLY
reduce noise when necessary. Therefore, you can safely
run G-ISOR 100 with all your ISO 100 images,
and not have to worry about loosing precious detail.
It also works in Photoshop batch mode, which is a
great timesaver for professionals who want to clean
up a large quantity of pictures all at once. |
