Export from LR mb size issues
Mar 6, 2021 11:57:59 #
If I want to print this photo for 8x10...when I export the photo using the standard jpg settings my mb goes down to 1 mb from 13 for a tiff. I know the 1 mb will not look good printed.
What am I doing wrong and how do I keep a higher mb for printing when exporting as jpg?
Process is:
Original file is a raw file 27.3 mb loaded in LR > then opened in PS
Resized via Photoshop using Image > Image Size - settings attached
Saved, went back to LR and exported
Thanks

The megabytes and the megapixels are two different things. If you export in best quality jpeg it compresses the megabytes but does not change the megapixels. So you will still have the same pixel resolution to print with. You can see this in action if you look at export as in Photoshop, you can set the jpeg for any pixel resolution and the panel to the left will show you the resulting file size in megabytes.

I would just resize in PS and export from there. One less step and you would maintain full control. I believe that the problem is being introduced through some export preset options. Have a close look at your "preferences". Good luck.

Why are you resizing at all? Why are you exporting before printing? Where are you exporting to? In Lightroom just choose the final print size in inches, pick 300dpi and print it. If you are exporting for some reason make sure all the settings are big. 100%, ten inches long size, 300 dpi.

The TIFF is uncompressed from the JPEG making the file size different. But, that doesn't mean it has more (or less) data, it's just that the TIFF format is uncompressed relative to the same file in JPEG format.
For the JPEG export from the original (not PS resized) image, consider using the 100% JPEG quality and don't resize any aspect of the image in the LR export assuming your original crop is at least 3000 pixels on the long-side for a 10-inch print. Other than needing to crop your image to the 4x5 aspect, the printer will address the sizing of the total pixels in the JPEG file to the intended print size in inches. You can check the pixel size in the LR display or just looking at the file properties of the LR export file.

Try these export settings: 3000 pixels on the long side and 300 dpi. I've printed beautiful 11 x 17 images from Bay Photo that were under 1 Mb file size.
How are you printing? Local (your) printer or pro Lab?

Why re-size for printing?
I just print the <largest> JPEG I have and let the printer driver figure things out.
(I DO match the aspect ratio for the paper used.)
Confused...

I don't have a printer. I will try what people suggested...thanks.
If I send it to Costco for printing I do the same, I send the largest correct aspect ratio file.

I would not resize the image. Print labs and if you print your own most printer drivers will handle the resizing. You should be using sRGB and jpeg, unless your printer (or lab) supports a 16 bit and Adobe RGB workflow. Most don't.
Setting the pixels per inch in LR does nothing when you specify the size in pixels or when you export without resizing - setting it to 6 or 1000 will not make a bit of difference. If you resize, then the ppi resolution setting will make a difference, and it will either downsample if you have too many pixels or up-sample if you don't have enough to match whatever you put in that box.

Lastly, an 8x10 does not need 300 ppi to look crisp, unless you are looking at it at a distance of 11". That normal, arm's length of about 19" all you "need" is 181 ppi for a nicely detailed, crisp print.

Rather than use the Export Module in LrC why not use the Print Module? Not only will the Print Module allow you to set-up presets for various printing, it will allow you to create an appropriate Jpeg for the final print. If you are using a calibrated workflow it will also allow you to imbed the ICC protocol for the printer at the lab you are using.

I' don't understand why folks use Lightroom for anything, but then that's just me.

With a subscription base of 22 million, the software probably does several things relevant and useful to digital photography.

I prefer Lightroom . It is very intuitive
