[quote=dalematt]I'm not clear on what you want, but I use a free program for resizing: bigger or smaller. Check it out and see if it will do what you need.

Sorry, I guess I wasn't too clear on what I was asking. I do know how to use the re-sizing tools in PSE12 in general. With one of my cameras, my photos have loaded with a large size 72 resolution and I wanted to change them to a 300 resolution to print - or to work on. (now my new camera is loading with a resolution of 350) I know the pixels are important and that you can't add them but just wanted to make sure I was understanding the process somewhat correctly and making the change without losing pixels.

Many of you are using other software to resize. Why is the software better than using Photoshop? Or do you just use the software when making extra large sizes.

As Amehta said, pixels are generally more important than resolution. If you simply want to change image resolution to 300ppi then open your image resize dialog box and change resolution from 72 to 300. But first, uncheck the Resample image box.

You can then see that the image will print @300ppi 6.4"x8.53" with no pixels lost or gained.

"Resampling" adds or deletes pixels altering an image.

Changing resolution without resampling leaves the number of pixels, and thus, the original quality unchanged.

Changing resolution to 300 on the 2nd image would result in a 2.5"x3" print if not resampled.

So if I change the 72 resolution to 300 and also change the pixels back to the original number of 2336 and 3504 with the "resample" checked, I am losing pixels and picture quality?

I would not touch the images, the are what they are. When you display them, whatever software is being used will automatically resize them for the viewing size. When you print, they will automatically be resized for the printer. Ignore the 72 and 300 resolution numbers, and just leave the pictures alone. Anything you do to them will have lower picture quality, though it usually isn't perceptible.

My question may also apply here. When I shoot a scenery photo it comes out great at a 4x6 print but when I go to enlarge it to an 8x10 I lose about 1/3rd of the photo due to cropping. I would like to make a lot of my photos print like they look out of the camera. I can use manual cropping but then this isn't a size that prints in a standard enlargement. I shoot Nikon D7000s and am wondering if I have to go to a special print shop. Please don't send me a load of numbers like the posts above because I'm completely lost when it comes to math of any type. Hope I said this right so someone can figure out what I'm talking about........

The first issue is that 8x10 has to crop part of your image. The D7000 sensor is a rectangle with the same shape as a 4x6 print, but the 8x10 print is a different shape. An 8x12 print is the same shape as the D7000 sensor. If I don't want to crop at all, I print 8x12.

How large would I have to go to get the dimensions of the 4x6 but in wall hanger size. Even if I print at 8x12 I don't get same dimensions as a 4x6 and the print still has that square look to it........

An 8x12 has the exact same proportions as the 4x6, it does not have a square look. If you want to go even bigger, common sizes are 12x18, 16x24, 20x30, and 24x36.

And then you would have to have custom matte and framing done for that size??

Some of these sizes, especially 20x30, are common sizes. You would not need custom framing.

You could look at frame options at a site like Michael's (frames) to see what options you like.

Often I am not resizing just to print but for the web or a photo book or other project. Sometimes the original size is too large to upload to something or a 300 resolution is required. When uploading a photo to this site, do you use the original size? Does that make the image take a long time to upload or is it too large for this forum?

The pictures you have are 5mp, those should generally work fine for the web. If you want to make it smaller, that's really about changing the pixels. You could change it by half, from 2560x1920 to 1280x960.

I do not think anything "requires" a 300 resolution.

I do not use the original size of my pictures, but they are 36mp. I will post either 9mp (1/2 size) or 2mp (1/4 size). I have occasionally posted a full resolution 20mp image, it takes a little while but less than a minute, and the forum software handled it with no issues.

When I do need to resize, I use FastStone Image Viewer.

If you resample changing the resolution and then change pixels to their original dimensions in one step you may or may not alter the image. It appears you don't (unless you make it a 2 pass process), but it takes more time than simply unchecking resample, and seems to be more prone to user error.

Normally, the only reason I resample is to create a small "copy" of an image for easy web transport and display.

The same applies when I use the crop tool. If I crop keying in a specific size such as 8x10, I always make sure the "resolution" field is blank, because if not, the image will be resampled during the crop.
