Resolution 72 px

Hello

When i crop a picture to 1024 px 768 px 72 px (resolution) and "save for web and devices" after on the properties of the pictures on window details i get the info 96 ppp on the resolution, when i choose 72 px on the crop.

Can someone help me ?

Thanks

Ignore the 72px part, it virtually has no meaning. (can not remember the source of that info)

It’s YES and NO depending how you look at it. Or in general, the complete (graphic) PHOTO requires 3 values while video requires 2 (actually more than graphic but it’s another story).

GRAPHIC

"1024 x 768 x 72pdi" is 72x larger than "1024 x 768 x 1pdi". And you WON’T see any graphic format without those basic requirements.

VIDEO

1024 x 760 are the main resolution part, then it requires the BritRate (similar to PDI) and FrameRate etc.. for quality and playing back etc. And with Video you may see more, especially dozens of different codec for Video and Audio part.

I suggest you read the next article:
http://www.dpiphoto.eu/dpi.htm

A picture does not have a 3rd dimention, only X*Y (1024 pixels * 768 pixels for example).
One pixel can be a (again, for example) 16 bit value for representing color and brightness.
The amount of DPI (dots per inch) is only of interest if you want a hard-copy (or photoprint) of the image, not for web use.

If the article says it doesn’t then I would suggest you NOT to read.

That’s wrong example.

DPI = Dot Per Ink
PPI = PIXEL Per Ink
LPI = Line Per Ink

Different words but same meaning, and they are part of ALL graphic formats. Now, you LOWER your DPI then VIEW (not printing) and you will see the 3D

The ‘I’ means inch here…

That’s what I meant too, but I don’t think you get it. And now with newer Photoshop you won’t see the term "DPI" and "LPI" like used to.

I don’t think any more discussing will be needed. You just create your JPG without the 3rd value you learned from the article you gave us, then I will CUT OFF my tounge asking for your forgiveness.

No you do not… lowering the DPI wil only cause the printed picture to look blurry. no 3rd dimention.
I you are able to put a 3rd dimention on a 2d surface (i.e. paper): you are a very very rich man.

I know wikipedia can be somewhat doubtfull, but:
http://en.wikipedia.org/wiki/JPEG

There is no sucht item there as the 72dpi (or whatever value) in the text.
A PICTURE HAS NO 3RD DIMENTION IN A GRAPHICS FILE, JUST x AND y

(I will not react anymore on this thread….)

As I said GIVE me a JPG without PPI just for DISPLAYING.

And I can tell you that I can have a much more detail printing from 1-PPI than 150-PPI or 300-PPI image. Do you get this far?

See above! I don’t say anything about 72-PPI specific, as I even tell you that the 1-PPI can even give more detail on *both* Printing and Displaying than 300-PPI image.

And I don’t say anything about 3-D either or the image has nothing to do with 3-D. Samething, people talking not just by opening the mouth but it will depend on many different thing. Example

– A tounge

– A mouth

– A vocal

– A brain

And additional thing like the specific lanuguage and whatever may need to make a specific sound.

Again, give me a regular/normal (1 or 2 dimention) without the 3rd value. I don’t care any format, I don’t care where you get the image. Or you can capture from a 2D movie whatever.
