the SI Pro v2.516-bit
image interpolation to the next level
new SI Pro v2.5 plugin, now compatible
with Photoshop CS3 and Windows Vista, gives
access to powerful and flexible
for customizing their own image interpolation
outputs. It is the result of many months
of development and based
on the feedback we received from many professional
photographers looking for the highest quality
print output. The SI Pro v2.5 plugin is the
next generation interpolation tool and replaces
the popular SI Pro plugin. This new essential
digital darkroom tool features improved
algorithms, added options to choose from
pre-set and custom paper sizes, pixel dimension,
margins, printer resolution and even interpolates
your images by scale. A powerful downsampling
option was also added to SI Pro v2.5 making
this plugin ideal for your interpolation
and downsampling workflow.
main concept of this professional plugin
is to offer one solution for all digital
files, including scanned film. It works
with both English and Metric unit systems,
therefore encompassing any printing media
Fine, Normal and Coarse SI Interpolation intensities as well as optional smart
sharpening can also be added to your desired interpolation method. For your

In the example above, SI Pro v2.5 was set with
the following options:
- Interpolation =

Color Noise = (Unchecked)
Method = Size for Paper
Size = Preset (30x20 Inches)
- calculated for the file aspect ratio.
- Margin =

I clicked on the "Save" button

It will run faster and provide excellent
results. For even finer Interpolation,
use the 'Fine' option. SI Interpolation
using the Fine option may take a longer

'Fine SI' with any sharpening option. The
Coarse setting will provide the fastest

method offered. You will be able to enter
the exact document size for printing output.
In this example, with an input of 26.97
inches width, the image height was automatically
calculated based on the image aspect ratio. Note:
Most digital SLR cameras support the 3:2
aspect ratio. The aspect ratio 4:3 is usually
supported by consumer digital cameras.
the above example, I chose a 3:2 aspect
ratio digital file on a 30 X 20 inch media.
As you can see, 26.97 inches will be added
to the width in order to support this aspect
ration. In order to fill out the entire
paper, cropping your image before running
SI Pro v2.5 may be needed.
I entered 300 Pixels/Inch (PPI) resolution.
This is the output resolution and varies
depending on your printing output device.
Finally, I added a 0.25 inch margin. (This
is a great time saver if you don't have
a borderless printer.)

is the difference between Custom Resize

plugin has an entirely different technique
and approach to image interpolation. The
SI Pro v2.5 plugin uses a unique and now improved
stair interpolation method and therefore
works with any digital file including cropped,
already interpolated images, or scanned
film. On the other hand, the Resize pro
plugins will only work optimally with the
camera file it was designed for. It increases
image size based on pixel contrast and
therefore needs the original camera file,
free of sharpening (Including in-camera)
to achieve superior results. So, if you
have more than one digital camera, shoot
film, severely crop images, or sharpen
before interpolation, then the SI Pro v2.5
plugin is the best tool for you. (Keep
in mind that any interpolation method works
best with unsharpenened files)
involved with digital imaging has heard
Genuine Fractals. This utility claimed to
do a better job interpolating digital images
than Photoshop's bicubic engine. SI Pro v2.5 uses a different approach to Fractals,
interpolated files to maintain a high level
of detail while keeping your photograph's
natural look. (Without the creation of
fractal artifacts) - It's also only a fraction
of the price. :-)
