large size print from a 60MB jpeg/tif

[Pedro_The_Swift]

As above I have couple of different types of files (of the same pic) I'd like to reproduce to frame/laminate
I'd like the finished product worthy of hanging on a wall...

I would like the finished size to be around 600 x 400mm, somewhere around there, its not critical.

What sort of reproduction options are available?

We have a similar sized canvas print of this image (Bucko remembrance ride)

I’ve used bestcanvas.ca before. They do a great job and it is not expensive.

Your topic heading kind'a males no sense.

60Mb jpg/tif is confusing.
is it jpg or tif? .. hugely majorly different beasts.

jpg can be carp. Nothing wrong with them, but compared to tif .. jpg is basically carp!

if you have a 60Mb tif file(which I think is the case), then for sure 24" print(or 600mm) is easily done .. larger maybe.

If you have a 60Mb tif, and you have software that will convert to jpg and maintain the same file size(bytes), is a faux conversion.
jpg, by it's nature is a compressed file type, so will always be much smaller than a tif file.

In a nutshell: you need to have a look into the properties of the file you have. What camera captured the image(or film if it was a film scan). More Megapickles simply = larger file size in tif terms.
In jpg terms, it will be larger, but not by as much if it were a tif file.
What you want to look for(or know) on the properties of the tif file, is .. is it 16bit? .. 8bit .. 32bit(very unlikely). Does it have any compressions .. LZW is the most common.

The other major factor is the actual image itself. How much dynamic range is contained in the image. ie. are there very bright bright bits, and very dark dark bits?
This can be important to maintain as much detail out of the print(digital to print, that is) as you possibly can.
eg. if the image has a lot of dynamic range(very bright to very dark areas) then find a good quality print service near you, and get a tif file to them.
If the image isn't as wide dynamic range as above, then a 10Mb jpg file version of a 60Mb tif file .. will do just fine. No one would tell the difference.

But expect conversion of about that scale:
A 20Mb raw file, will probably convert into a 60Mb tif file(at 16bit, no compression), which would then convert to about a 10Mb jpg file at the highest possible quality level.

And what software are you using too?

can you upload a small sample of the image to see? even a small sample will be easy to spot if the image has a wide dynamic range issue.

Thanks Arthur,, I think..

as above I have both a 60mb tif file and a 60mb jpeg,
I also have "cropped" copies of both types of files, but like I said I'm not really concerned about size or cutting anything out,,
I didnt convert anything or click the camera that took these...
I just like the pic and want it on my wall,, [wink11]


here it is in jpeg form...

Level the horizon first or it will always annoy you.

Making a large print is all about resolution. The file type only matters in regards to whether your print service will accept them or not.

A good print can be made from an image with 240dpi (dots per inch)

600mm / 25.4 = 23.622" x 240dpi = 5669 pixels wide.
Assuming the printer is also 240dpi in the vertical ( It may not be)
400mm / 25.4 = 15.748" x 240dpi = 3780 pixels high.

A 24mp image (6000x4000) would do nicely.

Dunno what happened. I made a reply after Ron, and it vanished!

Anyhow, for that image, jpg should be OK .. no worries.
I find it strange that your jpg is as large as a tif file.
Only probable reasoning is that tif file has a lot of compression .. or alternatively jpg has been uprezzed in some way, making it a 'faux' high quality file.

There are differences in file types, but again the reasoning for using one over another is when the dynamic range in the image can't be displayed by a jpg.
jpg is by design, 8bit colours. Tifs can be made as you wish. The norm is for 16bit.
In theory, if your tif was 16bit and not compressed, it should be at least 4x larger(usually more) than the jpg version of the same file.

The only thing I'd now recommend(Pedro): what software do you have for imaging? whatever you have, can you find the image properties. If you can do this, check for the colourspace of the image. One of two options will be either sRGB or aRGB(adobeRGB). Can make a slight difference.
The other tip for you .. if you can .. take the jpg version of the image to some print service like an OfficeWorks, or HaveryNormal ... or whatever ... you have close by, and get a typical 6x4 type print made up of it.

Note that some time back I once used OfficeWorks for a small print job, and wasn't thrilled with the Kodak equipment they were using. For the job tho(for mum) was good enough .. but I'd never get anything for personal use done there.
Until recently tho! .. had to do same again .. some photos for a funeral event thingie. No time to chase up any service other than the OW just down the road .. so headed there.
I have to say, very impressed now with the Fuji equipment they now used. Not badly priced too .. and played with the tablets and stuff while I waited a few minutes for the prints to finish. Easy stuff do do.
Do this before you get a large expensive print made .. basically, eyeball the thing that you think you're going to get first.
