Can I Crop a Perfect 8x10 automatically like in iPhoto?

[Bert Bigelow]

Bert, I think that may have been 4:27 AM PDT, not CDT....




Yup, you're right...but your message header says "Pacific"...like mine, so I assumed....

[Stephen C. Smith]

I usually use the crop tool. I simply type 10 inches in the width and 8 inches in the height box with 300 ppi in the resolution box. Then I draw a crop rectangle and move it around until it's where I want it. Then click the check mark to commit the crop.

Voila.

Perfect 8x10 every time.

"perfect" eh?
Hmmm.

Steven, I believe Mac's point is that by specifying 8 inches by 10 inches by
300 ppi, you're probably upsampling your image - unless the pictures coming
out of your camera or scanner are at least 2400 pixels by 3000 pixels (Beth,
there's that math again). Upsampling has been recommended against many
times on this forum, although lately we've had some guidance that upsampling
10% at a pass yields good results. In any event, just a word of caution
about forcing large prints to 300 ppi if you don't have the pixels in your
image at the outset.

Hi Chuck,

It does indeed resample. So, it's best to first change the resolution using
the "Image Size" window.

Select image|resize|image size (or right click at the top just above the
picture and select "image size").

When the Image Size window opens uncheck "resample image."

Then, change the resolution to 150, since the default is set to 72. A
resolution of 150 is quite sufficient for printing photos, assuming that's
what you're doing. Here's an example of the effect:

Original photo taken at 5.25MPs. Resolution default of 72. Dimensions
35.556 x 26.667. After changing the resolution image resized to 150, the
new dimensions are 17.067 x 12.8.

Now, if you use the crop tool using 8x10 (or 10x8) with a resolution setting
of 150 no further (noticeable) resampling will be performed.

This is definitely one of the major advantages of using Photoshop 7, since
you can set up custom tools for this purpose.

Today I changed the images in my shopwindow. One of the images is a 50x50 cm (20x20") print, printed at 254 ppi, so 5000x5000, made with a Fuji S2 Pro camera. This camera upsamples from a 6 megapixel file to 12 megapixel. I cropped the image to about 2800x2800 and upsampled about 10% each pass to 5000x5000.
It looks flawless.

Afterwards I tried to upsample this image up to 200x200 cm on my screen (at 254ppi again)in 10% steps. Just a matter of curiosity how far one can go.
This file was 20.000x20.000 pixels and on my monitor I could hardly see any degradation of the image at a 100 % setting. This bicubic upsampling is amazing!
I'm glad I didnot save this image with 7 layers....

+If you were not so good in math at school, 200 cm is about 80 inches. ;-))

I've been groping my way thru this forum for months and have gotten a wealth of info I know I couldn't get anywhere else.Your answer to Dan's question is the one I've been waiting for.It also is really a short course on sizing photos for printing.I followed the steps and came up with an excellent 5x7 on the first try,and a dandy 8x10 on the second.And it's soooooo easy!
I think that if one begins with a file with a whole bunch of pixels,printing 8x10's(or larger) should be a snap.
Thanks for unsnarling my brain.

Louis,

How kind of you to mention that after reading my post...came the dawn for you! I'm delighted I posted something useful to a few people. The thing is, the 'giving' is just reciting steps for one of my practices...the really exciting part is realizing those words on a screen allowed someone to put into place the last pieces required for comprehension. Sharing is a very nice thing, we all have something to contribute.

:)

Steve, I haven't been able to get a perfect match between my conventional monitor and printer, in spite of efforts to calibrate the monitor. I finally resorted to making some adjustments to the brightness and contrast parameters in the printer - that seemed to be a good compromise.

Depends on how much you crop.
You could have an image at 20ppi.

Or if you put in figure in resolution box, it upsamples.

I'd never been able to print a really decent 8x10 until your post-- did some OK ones,but the cropping was always the bugaboo,(I must not have been paying close enough attention to some of the other posts on the subject).I printed an 8x10 of my georgeous flowering yucca for a pro photographer friend who has been needling me about digital cameras ect.for too long a time.He was impressed,and tho he is retiring soon,has said that it might now be the time to "look into it" 'cause he's tired of the smelly lab.He is trying to convince himself that the things I'm doing are being done with a $30 PE-2.I've invited him to look into this forum(particularly the Challenges)if he needs further confirmation.This was so much fun.
