Genuine Fractals Impressions #4

I just ran another test on Genuine Fractals.  Here it is.

I’m working on an image for the Orange County Fair and I want to blow it up to 16X24.  It is Kolob Terrace taken with my 10D last year in Zion so the image size is 3072X2048 or 6 M pixels.

I use Image Print to make my prints on my Epson Stylus Pro 4800.  Image Print likes to print at two PPI settings – 180 and 360.  So here is the question: Can I get the same degree of sharpness with Genuine Fractals at 360 PPI as I can get with 180 PPI?

Genuine Fractals Impressions #3

I finally had a chance to perform a test with Genuine Fractals that’s been on my mind for some time.  This test was performed on an image from a Canon 10D with a 6 M pixel sensor.  The image was blown up to 24″ long at 180 ppi.

Now, there’s no way you can get a super sharp image of that size with a 6 M pixel sensor.  So that wasn’t the point of the test.  When I previously blew this image up there were a lot of artifacts that were enhanced, especially when I performed the output sharpening.  I spent about an hour with clone stamp and healing brush removing these artifacts one by one.

So the point of the test was to see how well the smooth areas were enlarged; that is, if GF could enlarge them without creating these artifacts.

Thoughts on Raw vs JPEG

I’ve been having a discussion with a friend regarding the benefits and challenges of JPEG and RAW file formats.  There’s already a lot of discussion on this topic out there but here’s a bit more.

The challenge my friend has with RAW is that the images are not as striking as JPEG.  In fact, she says the RAW images are rather flat and she’s right.
