So, who's all entering / thinking of entering the contest? I am contemplating it, waiting for an idea for a cover design to come to mind, but nothings happening yet.

Quote: " The top five finalists will be asked to resubmit their entry as a 115,000 pixels by 72,500 pixels image in bmp format. "


I was pretty surprised by the image size we need to work with though. It seems pretty massive considering the largest I've ever worked with is 4096x4096, lol, but I guess you need all that quality. PSP X can't even handle an image size that large when you create a new canvas... Maybe I won't be entering, lol.

Photoshop can handle an image that size, you just have to remember to work in an art-format is all.

Commonly for that sort of size you want a Canvas 10x7" at 1024dpi
Why they'd want it exported as bitmap format is a little beyond me though, why not ask for single layer .psd as most apps output to this.

That has to be BS, how can anyone save a 115,000x72,500 image? especially in .BMP format! that's a 23Gb file.

Yeah, in BMP form that would be massive, LOL. Lets see... that would take me roughly... 2 weeks to upload that onto a server for them if DC is to believed that it's 23gb.

Dark coder is right.

115,000 * 72,500 = 8,337,500,000
8,337,500,000 * 3 (24bit) = 25,012,500,000
/ 1024 = 24,426,269KB
/ 1024 = 23,853MB
/ 1024 = 23GB

well at a guess it's more likely a typo, but as i said above; it's possible with a higher dpi and not to incure a ridiculous hard disk usage.

the bmp format isn't restricted to purely pixel format. just never actually seen it use the pel system before myself.

I have actually seen images that are several gigs in size, so it wouldn't be too hard to believe. But yah, for a competition? Probably a typo.

I have a full legit version of PhotoShop 7 and it will only allow a maximum image size of 30,000 x 30,000 pixels! Thats a bit of a blow.

Thinking about it, even if they printed it at 600dpi (which would be very unlikely for a book cover as I am pretty sure they are normally printed at about 300dpi) it would print out covering *13,895,833 square inches! Thats *8,965 square meters! One heck of a big book.

Is it to be read by the orbiting Space Shuttle occupants?

(* of course my maths might be off - I did this quickly)

depend on the publication zappo, but most actually seem to use 1200dpi as it gives a nice photofine output.

1200dpi?! They would have to use some fine quality paper to benefit from that. Most packaging (boxes etc) are certainly printed at a maximum of 300dpi and you can get some pretty small readable text and reasonable quality photo images at that. With mass printing like I would expect with a book cover I shouldn't think the printers would be willing to print at that resolution (or would charge a fortune).

I have come across this situation before when asking a printing company for file specs and been given some huge figures for printing resolution. I can only assume its because that might be what the printer is capable of but its never actually used, especially in production runs.

The only email address I can find on the Digital Skills site is the one for the competition entries, or I would email them and query it.

Just had a reply from them... and it IS a typo.
The real size of the final image should be 11,500 by 7,250 and the Web site will be updated shortly.

Thats better. Its still quite high (approx 900dpi) but they may want an overly high res version 'just in case' and will end up shrinking it down before going to print.

Photoshop can do higher in future versions, however its not backwards compatible.

Hardly anyones home rig is going to be colour balanced for CYMK printing.
let alone the gadget to get it correct.
