upsizing in lightroom 1.2 - better to use photoshop?

[wrightm]

Hello, I need to upsize a lot of photographs for a photo library....from 23MB to 48MB....it is suggested to use bicubic smoother in photoshop CS.

I saw there is a way to do it in lightroom. Is it the same quality, process, method in lightroom for upsizing as it is in photoshop?

Is it better to upsize in photoshop CS rather than lightroom?
thx

Test it. It depends on the photo. LR 1.2 used a Lanczos algorithm which for most images should be as good as or better than PS.

In addition to what Victoria said -- in Lightroom you can set up an export preset and resize a whole bunch of photos really quickly. I don't know if that is as easily done in PS.

A step that large may require a purpose built upsizing application.
If you are already selling to the library ask them what upsize apps they are happy for you to use.

Alamy & Getty, both of whom I've worked with, are happy with bicubic smoother or something equivalent. I know it sounds silly, but hey! I've used LR's upsize in the past, and there have been no complaints.

Maybe I missed something-I often do. But you mentioned upsizing the FILE size from 23 to 48 MB. What about the IMAGE size, pixels? If you have a jpg file just converting it to tiff,esp.16bit, will increase file size without increasing image size.
I have seen where several places stipulate a file size when IMO that is secondary to image quality. The number of pixels is the important thing.
Just re-read op. didn't say file, but that is what increases if you increase MBs.

 

[Victoria Bampton]

Good thinking Ernie, the main stock agencies usually want 8-bit tiff 48-52mb uncompressed size - the measurements you'd get by opening the file into PS and going to Image Size to check the size.

 

[Mark Sirota]

Right. For some reason these agencies specify what they want in terms of bytes rather than pixels. It's one of those many awkward things that Photoshop has foisted on the community. There'd be a whole lot less confusion if they'd actually say what they want, which is 16 megapixels, with a bit depth of 8 bits/component.

From 8 Mp to 16 Mp is only a x1.4 linear increase, easily within the capabilities of either PSCS or LR.

I do upsizing in lightroom for 48mb stock images I submit to Alamy. I’ve never had a problem with the results I get from Lightroom and neither has Alamy. I used to do this operation in PS, but even with an automated script function, I find Lightroom is much more efficient. Just make an export preset and your off and running.

I don't disagree.
When I said:

My point was if a client or library wants images in a specific way, it is not usually beneficial to argue. Give them what they want, because they are paying.
