spicynuts Offline Image Upload: Off p.1 #1 · Upping resolution of JPGs for Printing Can't seem to get an results when searching, so links to other threads or straight up advice would be appreciated. I mistakenly shot an entire Romanian vacation in JPG instead of RAW. All shots ended up with a resolution of 96. I need at least 360 to print on my Epson 2400. What is the best way to up-res these while maintaining as much image quality as possible? I'll most likely print at something near 8X10. Dec 24, 2007 at 09:40 PM

John Ernst Sr. Offline Image Upload: Off p.1 #2 · Upping resolution of JPGs for Printing I've done this with pic with resolution of 72 Select "Image Size" . There you will see the dimensions of the image. Check the "resample box" In the resolution box type in the resolution you desire. Click OK. Now your pic is huge on the screen but scroll it down to the same size you saw before and notice the difference is the resolution. If you check back to the image size dialogue box you see that the actual size hasn't changed, just more pixels crammed into the same area. Give it a try, nothing to loose.

spicynuts Offline Image Upload: Off p.1 #3 · Upping resolution of JPGs for Printing Ok but isn't there software that does this better than PS and preserves quality? Dec 24, 2007 at 10:01 PM

John Ernst Sr. Offline Image Upload: Off p.1 #4 · Upping resolution of JPGs for Printing Don't know of any. Maybe a FM plug-in? If I had many images I would probably create an action in PS. You may also want to try to Google and go for "resizing images". John Dec 24, 2007 at 10:42 PM

tracknut Offline Image Upload: Off p.1 #6 · Upping resolution of JPGs for Printing When you say "All shots ended up with a resolution of 96" what do you mean? What is the actual size, in pixels, of the files? If all you're worried about is the "dpi" field in the file, that means nothing as far as the quality of the image. 8x10 at 360ppi is 2880x3600 pixels, that's what you need for that 8x10, and you may or may not need any resampling.

John Ernst Sr. Offline Image Upload: Off p.1 #7 · Upping resolution of JPGs for Printing paulhodson, The man asked how to increase the resolution from 96 to 360. Didn't ask why he wants to do it. Everything I've read tells me if I want to change the resolution, use the Image size dialogue box and type in what you want. Now, what's wrong with that? Do you know someplace else where you can change the resolution? John Dec 25, 2007 at 01:08 AM

Do you know someplace else where you can change the resolution? John From his question I think it is fair to say that he is confused by the whole subject of dpi and resolution. His question related to printing and doing as you suggested is not the way to adjust resolution for printing. The guidelines I suggested he read plus Mr Mouses's post (particularly http://www.fredmiranda.com/forum/topic/593287/0) give a fuller and better answer than I felt able to give - especially as I was typing mine at around midnight on Christmas eve!

dbren Offline Image Upload: Off p.1 #10 · Upping resolution of JPGs for Printing Just don't check the resample box as it is unnecessary to change the dpi, only when you WANT TO CHANGE THE PIXELS. Actually in the resize box just change the size to what you will be printing at (with resample UNCHECKED) and observe the resulting dpi, if it is not what you want then check the resample box and change the dpi (and pixels). As one poster noted, the dpi (of 96) is really irrelevant to printing as the dpi will be determined by the size of the print and the pixels. It's confusing when first explored but just foll around in the resize dialog box with resampling UNCHECKED and you will see how the dpi, picture size are interrelated and the pixels will not change (without resampling) Dec 25, 2007 at 11:31 AM

mhayes5254 Offline Image Upload: Off p.1 #11 · Upping resolution of JPGs for Printing I am confident that the "resolution of 96" that you mentioned is meaningless. The smallest image that the D70 can shoot in JPG is 1504 x 1000 and that is not the default. Unless you set it to "JPG small", the images are larger. If that is what you have, you only need to upres the images about 50% to get decent prints. With that level of upresing the results from photoshop are indistinguishable from the fancy programs. Read the references mentioned above to make sure you understand the dpi/ppi issues. As I mentioned above, I believe that the worst case scenario is you have an image that is 1504 pixels wide. Printed 10" wide, that gives 150 ppi on the page. That is low, but not far from the recommended minimum of 180 ppi (Luminous Landscape). I suspect the images are larger.

spicynuts Offline Image Upload: Off p.1 #12 · Upping resolution of JPGs for Printing Yes, they are larger. I had the JPG setting on the largest. Dec 26, 2007 at 05:08 AM

gfiksel Offline Image Upload: On p.1 #13 · Upping resolution of JPGs for Printing If you indeed have large size jpegs then don't worry about the resolution number. What matters is the size of the image in pixels. Just send it for printing and all you have to do is to specify the size of the print (in inches or cm). The printer driver will do all the necessary manipulations and adjustments. If you really want to change the "resolution" (again, you don't have to) you can do it in ImageSize of Photoshop. Just DO NOT check the resample box (John E advise is wrong) and type a number that you want (e.g. 360). While you're doing it keep looking at the pixel dimensions of the image and document size in inches (that would be your print size). The pixels dimensions should not change - that's exactly what you want. You don't want to change the number of pixels. On the other hand, the document, or the print size in inches, will change. This size should bigger, or at least not much less than the print size you want. But, unless you were shooting small jpges or you want to print a very large size you will be fine.

tomm101 Offline Image Upload: Off p.1 #14 · Upping resolution of JPGs for Printing 1) Save the images for prints as a TIF or PSD file before you do anything else to it. This way your image won't develop any more jpeg artifacts. If you want the size benefits of jpeg you can save the image to jpeg after you work on it. If you are sending it out to print some companies aonly accept jpeg, but do all your work first in tif or psd. 2)To resize turn off resample and just change to the resolution you want, the size will change as the res changes. Your image is x pixels by y pixels changing the resolution just takes then res number of pixels to the inch, so it is an abitrary number. If you have resample on it resizes the xy dimmensions of the image and the res with subsequent loss in quality. If you have say an image after you change it to 360 ppi and it is 7x11 but you want 11x14 then you use resample. Hope this helps Tom Dec 27, 2007 at 02:34 PM
