When Mobile Uploading From Canon Do I Resize It
Resize earlier printing or upload total size files?
Resize before printing or upload full size files?
This is my normal workflow when I have shots printed:
PP in Lightroom.
Export from Lightroom to full size JPEG with export sharpening practical.
Upload the full size JPEG to the printing service.
I assume the file is then resized by the press service to the right print size (ie. 4x6 inches).
Would I benefit from resizing the JPEGs myself? This would possibly generate a better export sharpening result? The files would be smaller to upload besides.
Or am I improve off letting the printing service do the resizing? I guess if my file does not match exactly their printer, they will have to resize anyway. In this instance information technology would exist better if they had the full size file to downsize from, rather than having to resize my 4x6 inch file?
Re: Resize before printing or upload total size files?
In my opinion, information technology is all-time to upload the full size image, as it gives much more headroom for resizing if the service needs to. it also allows you to exploit the total potential of the printer's resolution. Though, if it was necessary to resize before uploading (say if you had a slower connection and a lot of images) then it would probably exist of benefit to resize commencement.
Therefore, I'm inclined to say stick with uploading the full size files.

Re: Resize before printing or upload full size files?
If you lot photographic camera has a 3:ii aspect ratio it has the aforementioned aspect ratio as a 6x4 print I would upload the full size camera prototype if I liked the paradigm limerick as is.
If I exercise not like the epitome composition or I want a impress that does not have a 3:2 aspect ratio I would first set up the crop tool to the aspect ratio that the impress will be and crop the image to that aspect ratio with a composition of my liking. I don't desire the lab to have to make a crop of my paradigm.

Resize to 300 ppi
I always resize to 300 pixels per inch. Many press companies resize for speed because time is money therefore they may not utilize more advanced resizing techniques that photoshop uses. I have a PS script that automatically resizes all of my images.

Re: Resize to 300 ppi
300 ppi is non a size its a pixel density. A size is something like 4" ten 6". Depending on how many pixels you have in the ii:iii attribute ratio epitome ingather printing it 4" x half dozen" its Printing DPI will exist ready to some value. As long as the Printing DPI value is over 200 DPI I see no reason to resample an image'south pixels down or upwardly to print at 300 DPI. Press my Canon cameras 2:three 8MP un-cropped images at iv" 10 6" prints at 584 DPI Printing them 16" x 24" would print at 146 DPI and so I resample then to 200 DPI for 16" x 24" prints. I have had a impress made that was printed 6' 10 eight' on canvas that 3:4 image I only resampled that paradigm to print at 100 DPI and it looked dandy for you lot practice not view a 6' ten 8' image upwards close. The homo eye can simply resolve to effectually 300 DPI upwards close from a distance forget about it...

Re: Resize to 300 ppi
I concur merely that was a somewhat convoluted explanation!
Too I think a more accurate number is really close to 240-260 DPI merely it all depends on how far away you are. Any closer than about 6 inches and your educatee is at minimum aperture. It'south impossible to focus closer than this unless yous reduce the light entering the eye (Pin pigsty or squinting). At vi inches you should be able to see dots at 250-300DPI. So again how oft do people get 6 inches away from printed cloth?
Anything under 8x10 I print at 300. From 8x10 to 12x16 I'll print at 240-200 and annihilation larger than that usually gets 180-200 because no one's getting also close to it. (I practise this largely so I can go bigger prints out of my camera. If I could I'd print everything at 300 just because there's no reason not too [unless yous're printing on crummy paper that will blot the ink])

The point of my append was to provoke thought many just read thing similar 300ppi, put that in their memory bank as print epitome size to use. They practise not understand the reality of Digital Imaging. Its not that difficult if one just starts to think about what is going on. A convoluted explanation may only kickoff that procedure... Help them see thing from some other point of view...

Re: Resize before printing or upload full size files?
Good advice, but they don't provide this info (Pixum they are called).
On one page they list the minimum required resolution. And their upload software provides a feature to resize JPEGs earlier upload (I turn this off). On another page they require quite big JPEGs for season greetings cards. So somewhat mixed messages.
