    Raw / JPEG

    GoshawkCso Community Member

      Hi there. New to Lightroom4. I have my camera set up to take RAW + JPEG, it looks like its importing both the RAW and JPEG file into windows, but it appears that I am only able to edit the smaller JPEG version in light shop. I am looking to do the following:

      1. Verify that I am editing the RAW file

      2. How can I save the newly developed/edited image without overriding the original copy?

      3. How can I export edited (RAW) file to folder to save/burn and develop?

       

      Thanks in advance.

          1. The RAW file will have a "raw" extension, e.g. .NEF for many Nikon cameras, .CR2 for many Canon cameras, etc.

           

          2. Lightroom automatically saves your edits in the Lightroom catalog. You do not have to issue a save command. Lightroom never changes your original.

           

          3. File->Export (although I have no idea what the "develop" word is doing here, you "developed" the photo before you exported it in the Lightroom Develop module.

            DjP, thanks for getting back so soon. I just saw that CR2 (using Canon). Re: # 2 - so I can basically change whatever I want, but always go back to click "original"? - and it will revert back? Re # 3 - I see the size of the original CR2 file is about 32MB for a particular picture. When I go to export, the file size shrinks dramatically - down to 6 or so MB? Don't I want to be able to save this as a larger file size - ie making/printing v. large portraits? I would have thought after the export, file size would not have changed. When I am exporting, is it changing to a different file type? I basically want to edit the original RAW file, and be able to print that same RAW image.

             

            Thanks again for your help appreciate it!

              Re: # 2 - so I can basically change whatever I want, but always go back to click "original"? - and it will revert back?

              In Lightroom Develop Module, you can view the original and the edited by toggling with the backslash key. To go back to the original so you can start over, you would press the Reset button. You might also want to use a virtual copy.

              The Lightroom Print module will allow you to print the edited RAW. If you want to send the photo to a commercial printer for printing, then you have to export a JPG (some places take TIFF files as well), but commercial printers can't print a RAW. JPG is a compression technology, and is 8bits versus the RAW which is either 12bit or 14bit, so yes the JPG will be smaller. Nothing to worry about.

                DjP thanks again - you are one step ahead. So just to be clear on #3. I have a handful of RAW images that I have edited - I am satisfied and now I want to send them to a photo store to have them print a certain sized image. According to the above, all I need to do is simply click on the files I want printed > Export > Export as JPEG, then save to device and bring into store - is that correct?

                 

                Is there a specific reason for commercial printers not being able to / allowing for printing of RAW? I apologize if this is a silly question, but isn't RAW the best quality you can use? So for example, the quality of the JPEG image will be poorer/less clear than that of RAW? Let's say I wanted to print a life-sized mural - wouldn't exporting as JPEG and subsequent printing result in poor(er) quality?

                 

                Thanks again for your time this is very helpful.

                  Sounds good to me

                  Is there a specific reason for commercial printers not being able to / allowing for printing of RAW?

                  Because their hardware/software isn't designed to handle RAW

                  ... but isn't RAW the best quality you can use? So for example, the quality of the JPEG image will be poorer/less clear than that of RAW? Let's say I wanted to print a life-sized mural - wouldn't exporting as JPEG and subsequent printing result in poor(er) quality?

                  Converting a RAW to a JPG will cause some degradation of quality, but assuming you choose a relatively high level of quality when you convert to the JPG, most people can't see the difference between the RAW on your screen and the converted JPG on the same screen. Yes, there is a difference, and if you know exactly what to look for, or if you blow it huge, you will see a small difference.

                    Okay. So in the Export screen shot once JPEG is selected, all I need to do is adjust the Quality scroll bar ? Guessing 100 = Best? Is there anything to do from here on, for instance Image Sizing? For example, let's say I wanted to print all 5 of my images @ 16x20. Further it looks like resolution defaults to 240ppi, if nothing is clicked. Is there a setting/input that I can just type in each time that will maximize output quality based on each frame size?

                     

                    Also...is there a place in Lightroom where I can select a border/frame to go around the image before exporting?

                     

                    Thanks

                      You rarely need quality of 100. For most people, 80 or 90 suffices and saves disk space. See http://regex.info/blog/lightroom-goodies/jpeg-quality

                       

                      To print at 16x20, you first need to crop to 16x20 (or 4x5). Then in the export dialog box, under Image Sizing, you choose width and height to be 16inches x 20inches. PPI of 240 (or maybe even a little lower, big photos don't need as high resolution because they are usually viewed at a distance), and then export.

                      Also...is there a place in Lightroom where I can select a border/frame to go around the image before exporting?

                      Maybe there's a plug-in that can do this (I don't know), but Lightroom itself will not do this.

                        What the borders concerns: take a look at http://www.photographers-toolbox.com/products/lrmogrify2.php

                        This Lightroom plugin may well be what you mean.

                          Thanks for link that was helpful... getting closer. If I select the cropping tool under the histogram in the upper right-hand corner of Lightroom, and I lock aspect ratio and begin to crop, where can I see what size I am cropping to? For anything larger than 16x20, I would use the same methodology is that correct?

                           

                          Thx
