Printing format options (how to print type question)

Hi everyone,

I am going to be printing at home (or rather at work) my photos now (which I was usually sending to MPix to do)

I have just a complete utter newbie question here.

I open up my image, straight out of the camera and the format/image size info reads : (in PSCS3)

Pixels Dimensions
Width 2304 pixels
Height 3456 pixels

Document Size
Width 32 inches
Height 48 inches
Resolution 72 pixel/inches

Scale Styles (checked)
Constrain Proportions (checked)
Resample Image (check Bicubic sharper)

Ok, basically what I want to do is create a size of the image that is 16" wide and 24" high and of course with a resolution that is acceptable for a good print. (or just say any size to simply the idea here)

So I know to change the Resolution to 300.

But when I do that, the stats change to :

Pixels Dimensions
Width 4800 pixels
Height 7200 pixels

where in lies my concern. Where do the extra pixels come from and more importantly is there anything I should do or change to make sure I get the best print possible?

Sorry for such a complete newbie question here, but many thanks to everyone that reads and replies.

Try this...
The size you want in in. or cm.
resolution 360
bicubic sharper
Check the image to see if you want to sharpen it after upsizing it.

First
YOU DO NOT NEED SUCH A HIGH RESOLUTION FOR A GREAT PRINT!

300ppi or 360ppi is great for a small image that you view close up and see every tiny detail. The larger you print the further away you will view your image and honestly you could probably print at your native resolution and see very little difference (if any).

Your native res is 144ppi. If you feel you must resize your image don't double the size - Ps will add random pixels to generate your required image.

I'd be inclined though to resize only slightly - to a max of 200ppi. Your print will look just as good as it will at 300ppi !! You will get FANTASTIC output at 200ppi (try it)!

Not for a 24"x16" print! Why such a high resolution when there is absolutely no need? Also means a HUGE file size.

Ok, so basically,

I open the image size property box.

Leave all boxes at the bottom checked, but type in my values :

Width = 16
Height = 24
Resolution = 200

Leave the default option Bicubic as it is and click OK?

I have to agree with EOS_JD. Re-sampling destroys detail, printing at a lower resolution does not. While agreeing that sometimes re-sampling is necessary, keep it to a minimum and you will get better prints. You will be hard pressed to see the difference in an image printed at 200 ppi and one printed at 300 ppi.

Or just uncheck the last box (Resample Image) and type in my format size 16"x24" and have it automaticall reset the resolution to 144.

It should look fine at 144ppi. Although I must admit I do like to resample slightly when printing large prints. Your image will not deteriorate very much (if at all) going to 200ppi.

There are a few ways to set the image size. i prefer the use of the crop tool.

Select the crop tool and in the boxes at the top of the screen enter your image size 16in wide x 24in tall and set 200 in the resolution (ppi) box.

Take the crop tool and drag it over the whole image and hit enter.

You are ALL making this way more complicated than it needs to be.

Don't adjust anything! In photoshop, once you are happy with your image and ready for printing, go to "Print with Preview". Enter the paper size you plan to use and the orientation of the image.

A sheet of paper showing your image in the middle will appear. Is it big enough for you? or maybe too big? Then adjust the size in the percentage size box.

That's it, no need to resize, re- res or re- anything.

All I can say is ....
Give it a try and compare the result.

I have done so many times. I have a 150ppi 30 x 20 print on my wall and I can't tell the difference from a 6x4 (unless I look close with a magnifying glass)!

I'm afraid it's not as simple as you make out because the OP wants a specific size of print. Also I doubt that he/she will have a 17" wide printer required to print the image she/he wants. That being the case YOU NEED to set up the image correctly for it to be printed at a specific size.

Even so, I would ALWAYS set the size correctly in ps. By setting the %age in the driver you are still resizing thje image but without the same control. You are leaving it to Ps and the printer driver to add the pixels and also you are unable to see the effect on your image of increasing / decreasing the image size. Sometimes an image requires a little sharpening after resizing.

Whilst your method may work, for most professionals this is not a good way to print your images.

What could be easier than setting the size and resolution and printing as suggested?

I meant try it my way. Actually, this is a Scott Kelby idea.

i know

I've done it both and didn't see the difference. Why go for a huge file size? i have the SK book too. At the end of the day it's just personal choice. Both ways do a job - I lust prefer not to resample too much.
