Should one change the default resolution when editing

I use PS 7 and learning fast.

The default resolution when I open a photo, is set on 72 pixels per inch. This produces a photo with not a lot of detail. I have read somewhere that it is better to work on 300 dpi.

Is this correct?

And if so, how do I change the default setting?

Or do most of you work on the 72 dpi- it is just that the image that you see in preview, does not look the same once finished

Thanks

Hey avz10,

Resolution is only important when printing. It determines how many pixels are printed in each square inch of the image. The more important measurement is image size, meaning how many pixels were actually captured by the camera/scanner etc.

Both the resolution and image size can be viewed/modified inside the image size dialogue box.

Hope that helps

Thanks for your reply, but just look at the difference and help me set the preview parameters:

I am not sure that this will display well, but let's try:

I have a Canon 450D that takes excellent pictures.

If I open PS to edit, the quality of the picture is not what it should be, making editing difficult:

This is the picture as saved on my PC:

The best area to look at is to compare the back of the guy in the front's neck. Although it is a biiger picture, the edge of the neck is sharper.

So my question is, is it possible to get a better image while editing?

Hey avz10,

If you look at the top image, and then look at the bottom-left corner, you'll see your custom zoom ratio, and it's set at 16.7%. That means you're viewing the image at 16.7% of it's actual size. Grab the zoom in tool from the toolbox, or press CTRL + a few times to make it appear larger. A zoom size of 100% is where each screen pixel is displaying one pixel of the image.

Hope that helps

Hi Matt

Thanks for your answer- it is spot on and what I wanted to know. At 23% my pictures generally fills the screen and the picture is clearer/sharper.

Would it be possible to set the default to 23 instead of 16%?

Thanks

Hi avz10,

I wouldn't recommend working with 23% all the time to be honest. For example, if you look at an image that has text at 23% it will appear a little jagged. Try the same image at 25% and things will look much smoother. You'll see pretty much all of the image too.

So, it I use 25%, is it possible to set the 25% to the default?

Hmmm, off the bat I don't think it is. Not easily anyway. It's probably something you'd have to write a script for, and then run every time a new document opens with the scripts event manager.

You can resize to fill the screen using the keyboard shortcut CTRL 0.

Hope that helps

Yes, I think that's the way to do it.

There are quite a number of shortcuts! Is there a list somewhere?

Matt · VIP

Yeah, here we go, it's an article I wrote a while back-
