How Can I Create A High Resolution Jpeg File From?

How do you convert a low resolution JPEG file into high resolution? The process you are referring to is called scaling, changing an image file from one resolution to another. Unfortunately, this process works well and easily in only one direction - scaling from a large file to a small. The reason it doesn’t work so well going from small to large is probably pretty obvious to OP or t wouldn’t have asked in the first place. Unlike an image on a television episode or in a movie, if you enlarge an image, either analogue or digital, after a very short amount of enlargement you can see that there are no details in the details. What were fine lines in the small version become blurry smears in the large. Digital scaling is worse in some cases than analogue because, depending on how the scaling is done, those fine details won’t just be blurry, t’ll be blocky. But there’s is (limited) hope. A digital photograph can (sometimes) be scaled up successfully if it is done carefully with the right tools. First, there are already tools built into the higher-end post-processing suites like Photoshop. These tools recognize that sometimes scaling goes small-to-large and that a common problem is straightforward mathematical resizing makes for an image that, when viewed close up, just falls apart into blocky pixels. Long, long ago (20 years, maybe?) when a really high-resolution sensor was a whopping 1 megabytes, this scaling stuff practically ensured digital photography just wasn’t ever going to cut it in competition with film. Enter Genuine Fractals. This was a Photoshop plug-in that used fractal equations to interpolate sorta-kinda-not-really details into a scaled up image. Believe me, I played (and played and played and played) with GF for literally years to test it’s limits. And those limits were many. But it also could take a sharp 1 meg image and let it be scaled to surprising extents. Sometimes. Fast forward to today. Photoshop has it’s own fractal interpolation (or whatever t call it, I’m sure it’s proprietary) now that allows small images to be scaled up. Sometimes. Maybe. The tricks that I learned in GF still work - sometimes - in present day Photoshop. First, the algorithms that allow the appearance of sharpness to be maintained as an image is scaled up depend on figuring out the ratio of bright to dark in relation to the amount of scaling. tl/dr. Take it slow and in steps. If you have an image that prints as 4x5 inches at 300 dpi and you want to try to scale it up to 8x10 at 300 dpi, do it in increments. Scale it up just 1 inch at your target resolution. The another, then another, until you reach either a point where the details just don’t work anymore or you reach your 8x10. And if the details give out first, go back to the beginning and take it even slower. No guarantees, but yeah, I’ve been in a situation where I just absolutely had to get a crappy little (stupid, freakin’) jpeg up to a specific size without it looking like something out of a 8 bit gaming system and sometimes managed it in this way.
