p.1 #1 · Resolution in Capture NX2

Ok, here is my dilemma. I like the cropping tool and most of the adjustments in Lightroom but like doing my final adjustments with Capture NX2. So here is my problem. When I export the image with Lightroom I export them at 300dpi. Then I open the photo in Capture NX2 and do my final touches. I edited One hundred and eleven photos last night and when I went to copy to disk there was only 148mb size folder. I double checked and what had happened is when I go to edit the photo in Capture NX2 the program would default save as 72dpi. I had to go back and do all my final adjustments all over again. Talking about frustrating. I had to manually tell Capture NX2 to save as 300dpi for each photo when I went to save it. Did a Google search and couldn’t find where to default save the .jpg’s as 300dpi. Can anyone tell me how to do it?
After manually telling NX2 to save 300dpi The cd was 488mb. More what I was expecting.

Mine defaults to 300 dpi. I have no idea how yours is 72. Check your Lightroom settings, as I can't find any preferences to change the dpi settings.

Who cares waht the setting is in dpi? It only give you the print size, nothing more, it has nothing to do with file sizes.

It only means: 3000 pix so you can print in 300dpi->3000/300= 10 inch.

However, if I export from LR and set dimensions in pixels, I agree with you. DPI has no effect on file size. But, if I export in LR and set dimension in inches, DPI does have an effect on file size. I have no idea why this is, but it is. I am sure it is some setting in LR, but I haven't bothered to pursue it.

My lightroom isn't the problem. It exports 300dpi. The problem is when I open that file in NX2 and then save it, I click to save at the best quality but NX2 saves at 72dpi unless I Physically tell it to save at 300dpi. I give my client all there photos at 300dpi because they do print a lot of the files. They do crop the images at times so I want to give them a quality image.

Save a photo as 72 dpi and as 300 dpi and let them print the same size and what do you get? The same print.

Ok, I believe you because I don't have a lot of experience in printing. I will so some more research before giving my client 72dpi images.

thanks, but still deoesn't answer the question on how to get NX2 to default "save as" at 300dpi.

Thanks.

Of course when you export in physical dimension with a dpi value the output is effected by the size.

example:
10x15 @ 300dpi -> 3000x4500 pix
20x30 @ 300dpi -> 6000x9000 pix

But when you change the dpi in PS size window, you see change the photo size, but the "pixel" size stays the same(2000x3000).

So when you want to print real big, you can upsize your file with this tool and PS(LR, NX or whatever editor) resamples your file to a bigger file.

I’m confused. If I save a 1280x1024 file with a dpi of 72 the file size is say for instance 500kb but If I save the 1280x1020 file to 300dpi the file size changes to say 3mb but the file size is still 1280x1024.

Check your LR export settings. Make sure you aren't bringing them in at 72. If you are getting a different file size then something is resampling. The old bit about ppi not making any difference does not hold true for resampling.

When you do what you describe, you're resampling.

You're resampling the image. In Photoshop the 'Output Size' is referred to as 'Document Size'. I don't know about Lightroom because I don't use it. Point is, turn 'Resample Image' *off*, and you can set Document Size or Output Size to 1 dpi or 1000 dpi, and the File Size will remain exactly the same as long as Resample Image is turned off.

Thanks Osai and Jack, that makes more sense.

I appreciate the responses and help.
