Title: JPG for Juried Competition
Post by: Alan Goldhammer on June 12, 2010, 06:06:54 pm
I received the instructions for a competition at a small local gallery.  All entries (photo as well as other artwork) need to be submitted as JPGs on CDs.  This is OK but the dimensions required seem curious, "...Images should be no larger than 800 pixels in the largest dimension at a resolution of 300 pixels per inch."  This cannot be done in LR as the minimum size for printing at this resolution requires a 4" minimum dimension.  I can do it easily in Photoshop but the image ends up being of relatively poor resolution (the file size is 319 KB).  Nothing is said about what software will be used to view the entries (Windows Photo Viewer???  ).  If I do a simple 4x6 image from LR, I get an out of spec file but one that clearly looks better on the screen.  Has anyone come across this type of entry criteria?  I'm tempted to send both files along with a not to the person who is doing the judging.

Thanks for any thoughts.

I see it all the time. I prepare images of artwork for artists to enter art shows, juried competitions and for state arts grants. Your image prep must follow the written requirements exactly, including the spelling of the file name extension; jpg vs. jpeg. If you have Photoshop or Elements it's easy. In image size, specify 300PPI and then make the long dimension 800 pixels. It's imperative that you convert to sRGB before saving as maximum quality JPEG. You can't use Save For Web because it makes the resolution 72PPI. If you don't have Photoshop or Elements, e-mail me the images and I'll format them to the required specs and e-mail them back to you.

Foregoing the editorial comments about alleged juried art shows and their knowledge (or rather lack thereof) of digital imaging (ooops, guess I slid that in ;-) ).....

.... in LR - File>Export, choose your saving location, select JPEG as the file type, choose your quality setting, colour space as sRGB then in Image Sizing set your dimensions to 800 pixels on the long edge and resolution to 300 ppi.  Click Export and you're done.

Thanks to both of you.  Figured it all out with your assistance!!!

Nonsense:images have no any physical dimension until rendered.

Hear, hear!  I can't count the number of times I have tried to get that point across to several (presumably knowledgable) people.  It always results in either a vacant stare or a dispute.

While I fully agree with you, I think I should present a different point of view: magazine designers think in physical dimensions and resolutions; for them, "1200px" is a completely meaningless measure, while "4 inches at high resolution (300dpi)" is as clear as day (even if both terms refer to the same image, go figure). I guess that when your work moves around a physical media of fixed dimensions, you end thinking in physical dimensions and resolutions, not pixels.
