Resizing photos: HI! I have a Canon 70D. I have a photo 3648x2432 72dpi. I am putting pics on a CD and need them to be able to be printed at 8x10 (and still look good). Do I leave it...

HI! I have a Canon 70D. I have a photo 3648x2432 72dpi. I am putting pics on a CD and need them to be able to be printed at 8x10 (and still look good). Do I leave it as is or resize it and if I resize it how do I figure out what the new ratio is?

If I were doing this job I would take the files into my photo processor, Elements 11 in my case, set the crop ratio to 8x10, set the output to 300ppi, save it with a unique name or to a different file, then move on to the next picture and do the same thing until they were all done. Then go to the file where you saved the cropped files and copy them all to your CD. Hope that helps.

I shoot in Raw format - Then always save my photos to be printed in Tiff 99% of the time . If your going to print the photos in a 8 by 10 size . You will want to use the crop tool to see what may be cut off when converted to that size . You will be able to shift the photo inside the crop tool to a line what you want the most in the finished photo. Just remember that when you print a 8 by 10 borderless , it will crop more of the picture off . I sometimes have to add to my pictures to keep everything I want in the photo for a 8 by 10 size . They you can save to cd or dvd . This is just my way of doing it , can't speak for others

I appreciate your reply. I don't have elements or photoshop (yet) so I've been trying to use some old programs I already have (photo explosion and on line one called picmonkey). Don't laugh, I'm new to this lol! In none of them do I find anything about output or being able to change it.

Kuboto King: thanks for your response! The photos I'm referring to I have already taken in jpeg format. I was reading about shooting in RAW and saving to TIFF and now you have mentioned it so I do plan to try it out. :) Thank you!

I want to know how those images got to 3648 x 2432 AND 72PPI (NOT dpi)? Because right now that will print at 50 inches wide if you leave it at 72PPI.

Just change the PPI to 300 and you have an 8x12. Much as CurryPhoto described. To get to 8x10 you will have to lose some of the image and crop it. The 7x12 will give you the whole image.

Captain C: the file size is what came straight out of my camera. I took my disk out and uploaded them and that is the size it says it is. It also says 72 DPI not PPI. I am quoting what the properties details says about the photo. Are my settings in my camera wrong do you think that's why it's so big? I appreciate your help!

Also, I don't know how to change it to 300 ppi (or dpi, whichever it is). How do I do that?

I know Captain C is pretty knowledgeable in things like this, but when I work it out I come up with a ratio of 1.5. That means that if you want to have all of the picture in the new size, you would take your smallest dimension(2432) and multiply it by 1.5. That gives you (3648) the largest dimension. To know what size that is when you use 300ppi just divide the 3648 & the 2432 by 300 = 12.16 x 8.11 (effectively an 8 x 12).
If you crop them to a different size, which means you will lose part of the picture, the ratio will be: Using 5 x 7 as an example:
7in divided by 5in = new ratio of 1.4......and.........
300ppi would give you 2100 pixels x 1500 pixels(ALSO A 1.4 RATIO)

In order to change the ppi from 72 to 300, you need some sort of photo editor with a crop tool or a resize feature that has the ability to change how many ppi there are, and for printing 72ppi is NOT GOOD. You need at least 200 ppi to creat a descent print that is not all pixelated but smooth, and almost everyone uses 300 ppi because it does creat a better photo than 200ppi.

If you happen to have Photoshop, you can do a "batch resize" of a number of photos instead of one at a time.

I don't know about a batch resize. Can you change the length to height ratio and keep the picture from being deformed? Also, the placement of the 8x10 frame on the original picture might be critical to its final appearance and sometimes a vertical crop is better than a landscape crop. I don't know if those things are possible with a batch function. Unless you can correct my misgivings, I'm going to stick with one at a time. Let us know.

I have a handy little batch processor called PHOTO ELF that makes quick work indeed of re-naming, re-sizing and converting formats. It will also batch print photos with their file names attached. Available for PC only. I highly recommend it. I think it's $30.00. It is my best time-saver.

BTW, It also does a good job (if an entire folder was shot with less than good results) of color/contrast correction. It will rename a thousand files in a couple of seconds. I recommend it highly... and no, I don't work for them.

I don't think you can "crop" images via batch resize...that, I guess, should be done one at a time. Here is more info on Photoshop batch resizing (you can do this in Elements also): http://digital-photography-school.com/how-to-batch-resize-in-photoshop

Thank you CajonPhotog, that info is very helpful! What photo editing program would you recommend? Also, I'm wondering if my camera (Canon 70D) settings or something need to be changed so the ppi is 300 and the files not so large, so I dont have this problem in the future. I fell asleep reading the manual last night, and will keep researching, but if you know I would greatly appreciate it!
thanks again!!!!

TO LORIB:
I have the canon T3i(600D)and it also saves the image at 72ppi, and I also shoot with the camera preset at the largest file, which makes my files like yours, LARGE. I use Photoshop as my editor, which most people consider the top banana because they compare the other programs to Photoshop to see how they measure up, but PS is not cheap which is why there are other programs out there that do a lot of things that PS can do and perhaps a few things even better than PS. GIMP is one that comes to mind and is free. You would do well to search for image editor programs on line to see what each one does, ALL my experience is with PS so I cannot speak to the other programs. I believe in your canon menu you will find a setting for file size, and can change it to a smaller file in the camera, BUT with the smaller file size you lose some of the sharpness and clarity when you print the photo out. That is why everyone says to use the largest file size you can.
