Cropping in photoshop?

[Greg McCary]

When you crop a picture in photoshop how do you make the print come out the right size when you send it for print? An example would be the flag I posted. I cropped it to straighten the flag some. If I resize the photo in photoshop to 8 x 10 when I have a print made will it come out right?

yeah, it should. I'm a little unsure of what you're asking, but it sounds like you shouldn't have a problem.

Cropping and straightening are different.

1. Straighten the image.
2. Crop to remove the 'open' areas along the edges from the first step.
3. Then resize to your printing dimensions as needed.
(You may want to crop to the appropriate ratio in step 2)

Do not force the perspective of the image to 8x10 by unchecking constrain proportions when resizing or the image will be distorted. Crop to the 8x10 ratio (i.e.1600x2000 is an 8x10 at 200dpi). That or the image size of choice.

Does this help?

That makes sense. When I get my film developed have the pictures put on CD. Then I can play with them in photoshop and then have them redone to my liken. But the pictures that I get back from the developer on cd are very large in photoshop, 21.44 X 14.22. I just want to insure when I crop the image, remove some of it, that my enlargement are correct. So you are saying to crop in ratio to 8 X 10?

They're 21" x 14", but at what resolution? Usually I make 8x10 prints and smaller at 300dpi but over 200dpi should be OK. The problem is that 8x10 isn't the same proportion as a full frame 35mm negative - 8x12 would be. You'll need to crop that 12" side down to 10" which can mean 2" from one side, 1-3/4" from one side and 1/4" on the other, 1" on each side, etc.

And yes, do the straightening first - then the cropping.

That makes sense now. Photoshop tells me the picture is 96 pixels per inch. The image size is 18.938 X 12.792 inches. The crop I am wanting to do is already going to take 2 inches from the sides so this will work out great. This comes off in the straightening process. You guys are tons of help........

I sent the cropped print to a local department store for printing and everything turned out fine. Thanks for your help everyone. This web site really is helping me.........

First, goto the image size and one of the settings is: pixels per inch and change it, just make sure the resample image is unchecked, and only then click on ok.

Will going from 96 to say 200 or 300 improve the quality of print that I order?

Printing at 200 - 300 dpi will be a lot better than printing at 96dpi. The problem is, you can't just change it to 300dpi from 96. Well, you can, and Photoshop will help out but you're adding pixels to the file which can't change the original resolution. So, you're not adding resolution - only pixels. There may be a slight benefit to doing this, but it's not like shooting at a higher resolution.

On the other hand, you can change the resolution from 96dpi to 300dpi if you let the size (in inches) of the print decrease proportionally. Basically, as long as the file size stays the same (in MB) then you're not affecting the number of pixels in the image file.

If you're at 21.44 x 14.22 at 96dpi, the pixel dimensions are 2058 x 1365. Once again this isn't the same proportion as 8x10 so you'd have to crop the long side, but it could be printed at 170dpi (1365 pixels divided by 8" = 170). This should produce a pretty good print.
