I think such features would suit ImageTarget well.

Interesting - the next release has a Gaussian Blur capability.
Great!
What
sort of degree of blurring / downsampling / denoising did you use?
I experimented with bicubic downsampling (to 25%), Gaussian Blur (Radius
0.7 ... 5 -- equates to approx. 2 ... 15 in ImageTarget) and the "Reduce
Noise" Filter of Photoshop CS3 with "Strength" 7...10 and all other
options set to 0.
Before reporting on the results, I have to discuss some strange side
effects I noticed in conjunction with different source profiles (I will
do that in a separate mail).
Does it have the effect of lessening the texture from the canvas?
Yes, basically you loose some texture/details in very dark or colorful
regions and come down with a less desaturated, overall closer to the
original result instead. Your blur slider is a very comfortable way to
balance assets and drawbacks. In very challenging cases, one can still
make two versions and compose them in Photoshop.
There is also a 1:1 zoom feature for ImageTarget on my wish list ;-)
Good idea - that's implemented too. For now (i.e. until I add a
popup-menu) right-click the image to toggle between scale-to-fit and 1:1
panned mode. The three previews are kept in sync, so if you pan to part
of the image and flip to another preview, the right part of the image
will be displayed for comparison.
I love you, Alastair! ;-)
Your application gets exactly to the point: It's a very smart and handy
tool, providing all features needed to achieve the "optimal"
reproduction -- not more, not less.
Thank you,
Klaus
