![]() Īre the upsizing in ACR which Jeff recommends identical between ACR 4 and ACR 6? Nope, ACR 6 processing is actually improved! So the techniques described in Photoshop are identical should you go that route, the upsizing and ACR pipeline are different and improved in more modern versions of ACR (certainly ACR 6.X). Point in fact, if he had attempted to upsize an image in Photoshop CS2 (which was the current version of Photoshop when Jeff Schewe’s articles was written and mentioned as being used in the article) and CS5, he would have seen that they are identical! Upsizing the same image using BiCubic Smoother in both, then using the Apply Image command>subtract command, as described in this tutorial ( ), shows they are pixel for pixel IDENTICAL. K once again made a comment without doing his homework! He should practice scientific testing. What should be taken with a grain of salt is the quote above. I'd practice any of the methods mentioned with a grain of salt or just seek more current tutorials all together. Thanks for your thoughts and time to reply!Īndrews' link is extremely dated. So other than suggesting the purchase of a 5D Mark II or stitching together several images, what has been your experiences with interpolation programs and which do you prefer? I'd also sincerely appreciate any suggestions on the right post-sharpening techniques in CS5 to possibly accomplish the same thing. The other programs were MUCH faster so you could easily evaluate each change to their settings. The clunky response time made the program very frustrating to use and their phone tech was not much help either. It didn't seem to be a system issue as my set-up and video card exceed their recommendations. On the first go-around, (without too much knowledge of what I was doing) Perfect Resize (GF) seemed to provide the best rendition without being too sharp in areas that didn't need it-however it was also slow as molasses (not when rendering the final output, but each time I'd tinker with a setting it would take forever to respond while the other programs responded almost immediately). In experimenting, it's clear that results depend on how adept you are at using the appropriate settings for each program and for the individual image. But so far, I haven't been able to get the CS5 output to look as good as the others. I also wonder if CS5 can do just as good a job if I knew how to employ better sharpening techniques after enlarging-thus alleviating the need to buy a plug-in altogether. It's really more of a printing software, but apparently does a nice job on resizing as well-at about half the cost. I've also read several comments suggesting QImage. įor anyone interested in this topic, I did find an interesting tutorial on enlarging at Cambridge: It explains some of the different interpolation methods used by some of these programs. The "industry standard" (GF) provided the least guidance, saying "check our tutorials." I'd already done that, they were pretty basic. I sent an email to each company asking their recommended settings for enlarging to canvas and received varying replies of helpfulness. ![]() You really need to understand the best settings to use for each program to fairly compare results. ![]() But it gets a little more complicated when comparing image quality on final output. It's easy enough to compare features and ease of use. I've downloaded trial versions of Perfect Resize (latest version of Genuine Fractals), PhotoZoom Pro 4 (BenVista), and Alien Skin BlowUp. I've read a lot of reviews and tried several programs with varying results. As these programs continually upgrade and improve, I'm interested in hearing some current opinions and experiences. Hi, I'm looking for input on the latest software programs used for significantly upsizing images (ie for canvas printing etc).
