Jeff, we fully realize most of the above. However, digital projectors, like most any other device are not ALL the same. Some will project a better image than others regardless - they all have lenses do they not? Not all lenses are equal. As far as affording - just what dollar value are you intimating? PicturesToExe cannot - will not - MAKE a better image nor will any other program including Irfanview when manipulation is not to be done after the image has been submitted. PicturesToExe provides better and easier image sorting and rearrangement than any other like program we have looked at. That is the reason for selecting it - so far. JG>It you're judging digital images, it should likely be on the basis of a print JG>from a good dye-sub printer, not a projected image. If the projected image is JG>what you have to go with, you must accept the limitations of the device JG>displaying the image in the first place... No, the digital imaging is to be a separate category as opposed to prints, slides, etc. The limitation of the device? That is what we are trying to determine for each possibly considered projector. What is the limitations of particular digital projectors, therefore which ones are best? They can't all be the same, can they? Have you ever gone to a workshop presentation by a "master" photographer when he uses a digital projector for showing his work and giving instructions aimed at teaching one to do better photography? They try to select the best digital projector available for that purpose. That is what we are aiming for.
