Photoshop Top 40, Feature #3: Image Size

When I first pitched my Photoshop Top 40 podcast idea inside lynda.com, my producer gave me a wry grin and asked me what my Number 1 feature would be. Without hesitation, I announced "Image Size, of course!"

I later decided a couple of features earned higher honors. But I still consider Image > Image Size to be indispensible. It's the determinant of image detail, the seat of resolution, the place where your megapixels live and die. If Photoshop eats and breathes pixels, then Image Size is the program's stomach and lungs. Whether you're sizing an image for output or downsampling it for the Web, Image Size is where the action is.

This Week's Winner, Next Week's Hint

We had a record number of correct answers for Feature #3. Chosen at random, this week's Photoshop Top 40: The Final 10 Contest winner is ozmopolitan of Chattanooga, TN, who exactly nailed "Image Size." Congratulations, ozmo!

Now it's time to guess Feature #2. Hint: This feature is Command Central for just about everything you do inside Photoshop. And I'll throw in one more: If Image Size is Photoshop's stomach and lungs, Feature #2 is its brain. Keep an eye out for my newsletter in your email inbox (or spam folder ;-).

Feature 3 Image size

Very good and thorough explanation!
But I regret that the pixeldimensions size ( in top of the dialog box) isn't explained.
Why does the value that is mentioned here differ from the actual imagesize on disk?

Feature 3 image size (reply)

Are you referring to the “dimension” (ie: width x height) or to the “theoretical and somewhat arbitrary” amount of bytes it occupies on your hard drive ?

My guess is that you, like millions of others (including myself)
are getting confused over the old question about:

Image Size vs File Size vs Pixel Dimensions vs Saved Size
...or, When is File Size not File Size?

Deke does a great job on most of the #3 lesson but he did skim over this
point rather lightly... the URL (below) might help to clear things up for you.

Hope this clears things up.

Feature #2 new

Layers >< !

This is my sad face (*_*)

Just realized my guess for Feature #2 was already done. Is there any chance I can revise my official guess?

Pretty please? (My sig is so very appropriate right about now, too.)

Changing Image Size Default Settings

Image Size is the one feature I use the most. But I almost always use Bicubic Sharper (best for reduction). Is there a way to make this the default reduction? The default method should be user selectable. I even have circumstances when I'd like to set the default to be Next Neighbor for a while (yes I do lots of work with resampling screen shots for printed documentation). How can I change this default?

Try this

Hey Chas,

Navigate into Preferences, General, and look for Image Interpolation (should be near the top). Make your selection, choose OK, and that should get you going!

Thanks

Oh geez, there it is staring me in the face every time I open Prefs>General. I've gone past that setting so many times and ignored it while on a search for other settings, that it became background noise. That's the problem with a complex GUI like this, we become habituated to seeing only the features we use, and the ones we don't use become invisible.

200%!!!

Deke, you sit on a throne of lies.

You said you were going to show us the differences between the 3 image resizing modes, and then run through them again at 200%. Well, you didn't. And apparently you didn't actually watch the finished video because then you'd know that a) you didn't and b) you absolutely needed to do it. I could see essentially no difference between the three images at the scale at which you presented them (at least on the video podcast...is there a higher-res version around somewhere?).

Great series...despite your broken promises.

I don't sit on a throne of lies

I lie on a bed of lies. But you're right that I failed to show the images at 200%. I suck! Even so, I'm so damn responsible. So here's a demonstrative PSD file. Turn the layers on and off and view 'em at any dag-gum size you wanna. Here's the file. Right-click the link and choose Download or Save. Warning: It's a big file (> 5MB). And it's based on an original from Miroslav of the Fotolia image library.

Best intro to a comment ever, Flimsy

I'll let Deke defend himself while I sit back and enjoy "throne of lies."

Good call drukepple

but it's much faster to just open a photo, make the changes on your own system, and see the diff... just say'in.

Feature #2
