In Topic: Photo Resolution

23 July 2014 - 01:18 PM

When I drag an un-resized photo into a layer Elements 11, which I now use, it appears that the resolution is 300, which is what the setting for the background layer is.  Does anyone know if I can stop resizing all the photos before using them in my layouts?

In PSE, you can simply drag your high resolution photos onto your 12x12, 300 dpi canvas.  The program automatically fits the photo's pixels in as 300 dpi, as Jo described above.

 

(A low resolution photo would appear on the canvas as a very small rectangle which is totally OK, if that is the size you want it printed at.  Enlarging it would result in blurriness, although for the purpose of blending it into the background, I find using low resolution photos OK.)

 

I am shocked that Paint Shop Pro degraded your high res photos when you dragged them onto a canvas and resized them.  I am not familiar with that program, but I understand it is a very good product.  If I were to guess at an explanation I would say that the algorithm for resizing via dragging, is really outdated.  Reminds me of Adobe PhotoDeluxe from 20 years ago, where resizing using the type-in-new-dimensions method worked beautifully, but the drag-in-the-sides method produced a degraded result.

You're welcome, MariJ.

 

More about resizing:  An image has a finite number of pixels.  The bigger you want to print it, the more you have to spread the pixels out.  This creates blanks between the pixels which results in blurry prints.  In other words, as the print size goes up, the dots per inch goes down.  The more pixels you start with, the more you can enlarge the print before it starts to get blurry.

 

Push the pixels in tightly (i.e. 300 dpi) and the image file prints sharp; spread the pixels out (e.g. 100 dpi) and it prints blurry.

It's very helpful to understand the difference between "resizing" and "resampling".

 

Resizing:  Take the number of pixels in the image and spread them out (to print over a larger area) or pack them in tighter (to print in a smaller area).  The file size stays the same.

 

Resample:  Remove pixels.  The image size and the file size gets smaller.  This is what we all do when we create a JPG version of our pages for uploading to the gallery.  Once you remove pixels, you can't get them back.  You have to go back to the original, unresampled image.

 

Barb, in your first photobook, you must have used resampled photos.

... the rep asked me what the resolution of my photos was.  I told her it was 72.  She suggested resizing the photos to 300 resolution and to redoing the book.  The print quality of the resized photos was perfect.

Most people misunderstand resolution.  You simply want high resolution images for print purposes and low resolution images for web display.  High resolution photos have MILLIONS and MILLIONS of pixels.  If you check your photo's properties, you will see the pixel dimensions e.g. 3072 pixels x 4608 pixels which is just over 14 million pixels.

 

On the other hand, the scrapbook pages in the Scrapgirl galleries are 600 x 600 which is only 360,000 pixels, or 0.36 million pixels.  You can absolutely print them at 300 dpi - the problem is that there aren't that many dots (pixels) so at 300 dpi, you can get a nice sharp 2 inch by 2 inch print.

 

600 pixels wide divided by 300 pixels per inch gives you 2 inches wide

 

ALL digital photos taken by digital cameras are "72 dpi" - this is meaningless.  Look at the pixel dimensions.  As long as you have enough pixels, you will get a sharp print.  Divide the number of pixels wide and the number of pixels high by 300 and that will give you inches.

 

3072 pixels x 4608 pixels ---> 10.24 inches by 15.36 inches.  This means I can print my file up to size 10.24 x 15.36.  However, if I want to print it as a 36 inch tall poster, it will be fuzzy.

 

4608 pixels divided by 36 inches = 128 pixels per inch which is not high enough for a sharp print.

You are not switching computers, so no, you can leave everything as is.
