Photo Forum / General Photo Topics / Australian Photography / February 2007Enlarging digital images--- example and explaination
Poster prints (and larger) with resolution and clarity equal to the original: 6.3 Megapixel images will usually go to 24" x 32" (36" APS size) and way, way larger if you care to introduce a "viewing distance" equal to the distance from the image, needed to view all the image without moving your head. For a couple of years now I've endured taunts, ridicule and personal vilification from a few narrow minded people who thought they knew it all... How could most of them? The basis for me providing samples and confirmation for investigation was QUALIFICATIONS TO PASS JUDGMENT. All but one, never had any. When I posted how I had enlarged a miniscule (less than 400k) image into a two meter wide poster for a newspaper office, the nature of my detractors became obvious... I set them up and they took the bait... So... I have in the past made statements like: "Enlarge from a postcard size image to a poster" "Up to 1000% enlargement" "Add data to an image to enlarge it" All perfectly true and ridiculed by zealots looking for recognition they have no right seeking in the first place. Why? Because they have no training or education which may qualify them to make contradictory statements. Nothing qualifies them for slander and defamation. I have been able to, and founded a hugely viable business, on enlarging digital images using the mathematics of Interpolation. Until now I have chosen to protect my industrial secrets and formulas by refusing to provide enlarged digital images or pixel level crops of enlarged images to anyone for examination... Until now. I really would have thought some of the people posting contradiction would have discovered by now, they are wrong... Not so, it seems. So maybe today the disbelievers and pundits will be satisfied. Probably not knowing their form. At least today they get their wish. A full pixel crop of an enlarged image. The process has developed enough I now leave no information in the files which they could use. I have provided an example image which I enlarged to poster size and a full pixel crop of part of the ENLARGED image to demonstrate that not only is it possible but possible at virtually zero loss of sharpness and detail in the final image. http://canvas.photosbydouglas.com/interpolation.htm You may also be interested in this meter high enlargement from a Canon 20D image. http://www.photosbydouglas.com/fun/tryptich-surfers.jpg The lady's smile is due to a sell out exhibition. Use the link at the bottom of the text on that page to take you to the actual examples and explanation. Anyone who wants to have the original (un-enlarged) image only needs to ask me without aggression or taunts and I'll supply it as an attachment to an email only to a valid domain address (no hotmail, Yahoo or Gmail).

Wedding and Portrait specialist: http://www.photosbydouglas.com Canvas prints and Digital enlargements: http://www.canvasphotos.com.au Wedding Photography anywhere on the east coast of Australia. > http://canvas.photosbydouglas.com/interpolation.htm Just a big blank grey box in my browser(s) ? -- Jeff R. : > http://canvas.photosbydouglas.com/interpolation.htm : [quoted text clipped - 4 lines] : -- : Jeff R. Someone else in another group said the same thing. I don't have a problem in IE or Mozilla using Bigpond or my laptop via a mobile phone modem. It works too with my Linux system via satellite at my home on Moreton Island. The site is hosted in the USA... Maybe Optus (who are using a transparent proxy server) are blocking my host's entire IP range? This happens sometimes. Godaddy probably host porn sites so it would not be unreasonable to think they could get blocked entirely. Try this link which is in another part of the US on a different backbone: http://www.brisbaneweddingphotographers.com/canvas/html/interpolation.htm If it doesn't work, I'd appreciate you letting me know. Douglas > Try this link which is in another part of the US on a different backbone: > http://www.brisbaneweddingphotographers.com/canvas/html/interpolation.htm > > If it doesn't work, I'd appreciate you letting me know. > > Douglas OK. That works now. Specifically: http://www.brisbaneweddingphotographers.com/canvas/html/enlarge-example.htm and http://www.brisbaneweddingphotographers.com/canvas/html/example-clip.htm (the gulls and the detail from same) now appear OK. The page (text) loads fast, there is a short but noticeable pause, then the images appear. Previously both yielded only a blank (the "empty" transparent gif you're using to stymie copying) and the png images never appeared. I'm using Firefox, but the same thing happened in IE6. -- Jeff R. : > Try this link which is in another part of the US on a different backbone: http://www.brisbaneweddingphotographers.com/canvas/html/interpolation.htm : > If it doesn't work, I'd appreciate you letting me know. : > [quoted text clipped - 3 lines] : : Specifically: http://www.brisbaneweddingphotographers.com/canvas/html/enlarge-example.htm : and : http://www.brisbaneweddingphotographers.com/canvas/html/example-clip.htm [quoted text clipped - 8 lines] : -- : Jeff R. Thanks Jeff. I gave up on the gif blind. Anyone who intends to steal my image won't be stopped by that subterfuge. Basically I figured I simply wouldn't post anything of commercial value to me and so far it's working fine. That site is on a fast link owned by mydomain.com who I wholeheartedly recommend to anyone needing a cheap, fast server and stuff all customer support! Thanks again.

Jeez Doug, I am still waiting on the samples you promised to post to me 3 or more months ago. : Jeez Doug, I am still waiting on the samples you promised to post to : me 3 or more months ago. Come on Avery... Don't become another Mark Thomas. The rules are plain enough. A Street address and qualifications... That's all I ask. Douglas >: Jeez Doug, I am still waiting on the samples you promised to post to >: me 3 or more months ago. [quoted text clipped - 3 lines] > >Douglas I sent you all that through your website months ago. You offered, in this group, to send samples to anyone that requested them. I have had no response except fot rather pathetic excuses whenever I have prompted you. This is just another. You don't deliver. : >: Jeez Doug, I am still waiting on the samples you promised to post to : >: me 3 or more months ago. [quoted text clipped - 10 lines] : : You don't deliver. -------------------- So send it all again by using the "reply to sender" option of your reader and you'll have it within a week. I'm not the perfect organiser I'd like to be but I do try to keep up with orders and requests from people... Sometimes the form mail on my web sites breaks, sometimes I stuff up, sometimes the text reader which separates spam from legitimate mail doesn't like stuff in the headers and spits it out. There has obviously been a stuff up with your request and I'll rectify it. Regardless of what you choose to think and say publicly, something must not have fitted with your original request or you'd have gotten it. What it was that didn't fit is irrelevant now. Send me your details and I send you the package. Douglas > : >: Jeez Doug, I am still waiting on the samples you promised to post to > : >: me 3 or more months ago. [quoted text clipped - 31 lines] > > Douglas LOL! : >: Jeez Doug, I am still waiting on the samples you promised to post to : >: me 3 or more months ago. [quoted text clipped - 10 lines] : : You don't deliver. -------------------------------- There's a funny thing, isn't it Avery... I'll be buggered if I can find your request in today's orders yet, yesterday you flamed me big time for not sending you an info pack. The email address attached to this message is a real one. All you need to do is hit the "reply to sender" button to send me your name, address and ABN details and you'll get the stuff. You must be on-line because you posted in other groups. What's going on mate? Do you want the samples or not? If you don't will you please stop attacking me the way you are?
