I have also run the same process using a color photograph with the same characteristics as the one mentioned above and with near the same result, still quite impressive.įor those who are wondering what type of photographs I used, it was that of the face of a child. I was quite impressed with Image Converter Plus, the program took five of these repetitions before any serious degradation of the photograph (minor blurring of features) had occurred. Most programs don't make it past the second stretching before serious degradation has evolved (Format Factory, though one of my favorites, has fallen into this category). It is the speed at which this degradation occurs that is the nature of this test. As most would note as with any photograph that is stretched, compressed, stretched and compressed again Serious Degradation usually occurs. For the programs that that passed this first step I continue to compress and re-stretch the image until the program fails to produce a good-quality image. The resulting quality should still be good or the program has failed and is not worth reviewing further. This test consists of how the program handles stretching of a black-and-white image (1600x1200 24 Bit Depth 600ppi) to 300 times its original size, JPG 24(True Color,YCbCr)Bpp image quality 100, compression mode baseline (1:1:1(11:11:11) default), quality should be good, then recompressing the image back down to its original size and back to 300 times its size again. Any converting program has to pass a baseline test for me.
