Can You Upload 300 Dpi on Tumblr
Lú_ bilang:
DPI is a measure of how many dots on ink impress on a square inch of paper. It'south irrelevant to how big a photo looks onscreen. PPI, on the other manus, is a measure of how many pixels (bits of light) are in a square inch; well-nigh monitors have 72 pixels per inch. Monitors can't show you 300 PPI because they aren't made that way (your photograph editing software merely pretends to do so if y'all tell it evidence you "print size"). You'll find that Flickr talks about measurement in terms of number of pixels.
You can have that number of pixels and and roughly catechumen it to figure out the size your prototype is at 300 dpi. An image that is sized to look keen onscreen at 1600 pixels on the long side (the eye "large" size on Flickr) would come up out about 1600/300 = v 1/3 inches long.
And hither you lot thought artists didn't demand math ;)
Most photo volume software volition do some resizing for yous anyway, and then y'all probably don't need to take your pixel count exactly right. Just not too pocket-size.

Thanks for the reply Lu ...and I know most of that. Except that math is wrong:
1600/300 = five 1/3 which would hateful 1600/72 dpi = 22.22 ...which would atomic number 82 ane to believe the smaller the dpi the larger the print.
How practice people have 300 dpi on Flickr?
My question has nothing to practice with viewing, simply for press. PS: not trying to be combative or a smart ass or anything. Just all the posts and replies I've read deal with viewing. I'1000 not talking about viewing, I'm talking about printing and honestly more on how people become their photos to 300 dpi on hither?

I but upload mine and they stay @ 300 dpi on Flickr...
Check your Exif before you upload.. Is it 300 dpi?
I'm thinking y'all demand to adjust that in your photographic camera...
Do you use Photoshop or other Photo editing software?

Information technology doesn't matter what dpi the setting in the paradigm file is - dpi, equally recorded in the exif data - has nothing to do with how an image is displayed and naught to exercise with how the image is printed.
If y'all upload an epitome that is 1800 10 1200 pixels, it volition print the same whether it is set to 72dpi or 300dpi. You can print that image at 25 inches by 17 inches (72dpi) or at 6 inches by four inches (300dpi) or 3 inches past ii inches (600dpi) - it doesn't matter.

It'due south a totally irrelevant question, I think. What exercise yous hateful past "have 300dpi on Flickr?" Flickr is not a impress.
I have photos that are 3000x2000 pixels, which ways, if I send them to a printer at 300dpi, they'll be ten inches on their longest side. If I send them to a printer at 200 dpi, they'll be xv inches on their longest side.
The actual "dpi" setting that you encounter on a file doesn't actually mean annihilation except to a printer who may default the size based on a combo of dpi and the number of bodily pixels. Simply information technology'south the actual pixels that are important.

@Pacdog ...thats my main reason for the question ...my photos are 300 dpi on the computer but plow into 72 dpi when uploaded ...wondering why some alter and some don't?
Just interested really...

@Brenda Anderson ...if you lot look in the additional info, some have 300 dpi, mine and many others are resized to 72 dpi.
I am sending them to a printer through Flickr, thus the question ...I do know dpi ha zero to practice with viewing photos on a screen.
Honestly though, your answer makes more sense than the 100'southward of others I've seen ...It'south like a compression ratio.

The dpi setting in the image data has nothing to exercise with displaying the photograph on the screen AND nothing to do with printing the paradigm.

Seems to me that OP is merely wondering *how come* that his photos alter the dpi number while other users''dip value remains unaltered, regardless of the importance of dpi.

The DPI value in the EXIF information is ignored. You can withal transport your prototype file to print without whatsoever EXIF data attached.

If you accept a 1600 pixel prototype and desire a 16in print, information technology will look like shit because you lot take about 100 PPI and about printing companies will tell you that isn't enough. If you lot desire a 5in so information technology will wait fine every bit the paradigm volition have almost 300 PPI. DPI is a thing with printers and is independent of the PPI in the source. Suffice to say that if the printer is doing 300dpi and so in the 16in example information technology volition deposit three blobs of ink for every pixel in the image and in 5in example it volition deposit i hulk of ink.
In that location is a threshold where the number of pixels in the image and the size of the print changes from looks OK to looks like shit. In modern press that is when there are more than ii blobs of ink deposited for each input pixel. So given the 1600 pixel image an 10in impress will look OK.

That is right - but it would probably await rubbish
If you have a picture with a "display size" of 1600x1600 pixels and you printed information technology at 1600 dpi then the picture would be printed as a 1 inch foursquare
If you printed it at ten dpi it would exist 160 x 160 inches - Over four metres square. If you printed information technology at 1 dpi then it would be 1600 inches along each edge - 133 1/3 anxiety or 40.64 Metres. If each dot was an Inch square and you stood far plenty away it would await fine!

Anywhere from 12 to 30 dpi is common for billboards :)

Don't forget as well that unlike press materials can cope with different print resolutions - canvass is much more tolerant of depression-dpi prints than glossy paper, for instance.

If yous have whatever doubts, y'all can utilise dropbox to share the images with your printer. I find that's a much easier way to share images for that purpose.
