What sizes do you all send you images in, to places like Colab photobox etc for printing?
Ie what Mb / Kb sizes are required to get a "good print" from and if you want say, a 10 x 8 print do you send it at that size?
I am just wondering what is the optimum digital size to get the best hard copies from, and also for speed in "up loading" ? I hope I have explained myself?Cheers in advance

I just send them as big as I have them :shrug:

:agree: photobox (others more than likely do to) have a guide on their site for the minimum requirements for separate print sizes.

I always upload the max resolution image even of i'm only ordering 6x4's
 
I always save at the biggest size needed and 300dpi for printing. I use photobox a lot, if you want different sizes then you need to make sure you use 'fit to frame' or the image maybe cropped if your dimentions differ to theirs. You end up with a white border sometimes. We tend to work to a 3:2 ratio these days mostly, which is what comes out of our camera ;)
 
I use Photobox a lot - and I send my shots at the size I want them printed - and 300dpi.
 
Surely if you send them the size you require, at 300ppi the files would be massive, and take forever to upload.:thinking:

yep...they take an age! I use their ftp thingy though :) and i do the ironing at the same time! ;)
 
:thinking:what is this i r o n i n g you talk of, some new fangled hobby;):lol:

Thanks guys I did "whack" a few over, just as a test before I posted the first post, as I had never used either, at full size and it did take "forever" I thought it was just me, getting it wrong as usual
I used photobax & colab as a comparison and photo box was far cheaper ( less than half the price on my few of 7x5's and 10x8's ) I just hope the print quality is as good.
Thanks Marianne, I found in photobox that you can actualy shift the crop box up down left right to utilise the best "crop" when it differs which helps
 
I have a quick question,

After I've cropped the image etc, the sizes will not be 3:2 anymore (as and when it's just come out of the camera).

So for instance, a 30"x20" poster has a 1.5 difference on it's length.
So I have to expand the canvas and make sure one side is 1.5 times longer than the other.

Does anyone else do this, or do you just click "fit to frame" and hope it doesn't stretch/expand etc?
 
30"x20" is 3:2 isn't it?

but I know what you mean...we offer our customers prices for the right ratios ie 6x4 12x8 etc and tell them we offer other sizes but that the photos will have a white border or be cropped to fit :)
 
I generally have the crop set to a specific ratio when im cropping a photo, generally for me 3:2, 2:1 and 1:1.
 
Sorry.. I didn't explain very well.

30"/20" = 1.5. So one side must be 1.5 times longer than the other.

So, say I crop an image to 800x600 (for arguments sake). This will have a white border around one of the sides (as it's only 1.33 times longer)... so I have to go back to the original photo, and make sure the selection will be 900x600 (so that the longest side is 1.5 times longer than the shortest side).

Otherwise, as you say, the image will have a white border.

I was just wondering if you have any quicker ways, than physically cropping the image, finding out what size it becomes, then deciding to go back and make up the lost.

An A2 poster is 16.55"x23.41", so you would have to make sure one side was 1.41 times longer than the other.

Or am I doing it wrong? :thinking:

why not make a crop tool to the dimentions you need with 300 dpi?

Thanks Marianne, but I don't know how to.

However, it makes perfect sense :)

I'll have a toy about with CS3 tonight.
 
if you are using CS3 then you will have not trouble with up sizing using the crop tool. you just fill in the dimentions in the boxes at the top of the screen 16.55in x 23.41in 300dpi and you can crop your image to your hearts content. Remember to add in the 'in' for inches though or it will make your pc go crazy and die if you don't have enough memory....I speak from experience! :lol:
 
Excellent!

That was brilliant. :) I'll check it out later.

Thank you!
 
Last night I sent my very first pic off to the printers. Thought I would take advantage of the £5 Photobox poster offer, so I sent an upscaled 300dpi 30"x20" to be printed on matt. The file ended up pretty damn big, but im sure it was worth the wait of the uploading. then once I receive the poster, im going to take it to get it framed and glassed. :)

If you enter 16.55 those dimensions it will attempt to crop the image to 4,965*7,023 so unless you have a 20 megapixel camera or have upsampled the image it will not work (or it might expand the canvas with a lot of blank space, not sure which).

If you leave the dpi box empty though you can use the crop tool to pick out as much or as little of the image as required and it will keep the proportions fixed.

Thanks for the input Mij.

Messiah, good job you remember to click "Matt" - I left it on gloss and they look like giant photos now lol.

Hehe. Well my thinking behind it was that if its going behind glass it doesn't really need to be gloss in the first place. I had a right job getting it ordered though, as it kept refusing the offer code for some reason.

I am assuming he is working on the photo that comes out of the camera to begin with.....if he is already thinking of an image 30" by 20" then surely it has to have a lot of info already there? Photobox will soon tell you if the image is too small anyway. I would still put 300dpi in the crop tool info if you are working on a large image. Am I stupid to assume soemone would be working on a 72dpi image 800px wide? I don't think so! I have never had any trouble cropping in the way I suggest :razz:

It is nothing to do with whether there is enough detail but simple mathematics. 16.55" x 23.41" at 300dpi means a resolution of 4,965 x 7,023.

The maximum size of files produced by a 30D is 2,336 x 3,504.

Oops, having just tested it you are right. It will automatically resample the image for the specified resolution using whichever format you specified in the General Preferences.

I knew there was a good reason I kept that box blank, I got the wrong one, sorry.

Incidentally, Photobox produce large prints (above 10" x 15") at 254dpi so if using them you should use that resolution otherwise they will have to downsample for printing.

that's useful info about photobox thanks...

No probs about the boxes on the crop tool...I just knew it worked ;)
