Today’s Question: In Lightroom Classic is there an easy way to find out if all my photographs in the Catalog have keywords?

Tim’s Quick Answer: You can indeed locate photos that do not have any keywords in metadata by creating a Smart Collection based on this metadata criterion.

More Detail: A Smart Collection in Lightroom can be thought of as a saved search result. And as it turns out, one of the options for defining a Smart Collection is to filter images based on an absence of keywords.

To get started, click the plus (+) symbol to the right of the Collections heading on the left panel in the Library module, and choose “Create Smart Collection” from the popup menu. In the Create Smart Collection dialog that appears, enter a meaningful name in the Name field, such as “Photos without Keywords”.

Next, click the popup at the top-left corner of the “rules” area, which is the large white box that takes up the majority of the dialog. Choose “Keywords” from that popup. In the popup to the right of that, choose “are empty”, meaning you want to filter images based on a Keywords field in metadata that is empty.

You can choose whether you want to save this collection inside of a collection set (and if so which set) in the Location section of the Create Smart Collection dialog. Then just be sure that there are no other rules listed for your Smart Collection. If anything other than the “are empty” rule for Keywords is listed, click the minus (-) symbol to the right of that rule to remove it.

When you’re finished defining the Smart Collection, click the Create button at the bottom-right of the Create Smart Collection dialog. You can then navigate to the Collections section of the left panel in the Library and select the Smart Collection you created in order to view all images that do not have keywords assigned to them.

Note that the Smart Collection will dynamically update, so that if you add keywords to an image within the Smart Collection, it will automatically be removed from the Smart Collection. And, of course, if you remove all keywords from an image, that image will be automatically added to the Smart Collection.

Today’s Question: Is there an add-on GPS accessory you would recommend for a DSLR without a built-in GPS receiver?

Tim’s Quick Answer: GPS accessories are available for a variety of different digital cameras, including digital SLR models and others. In addition, you can use a separate device to record a track log during your photography, which can later be synchronized to the photos you captured during the recording of that log.

More Detail: Some digital cameras include a built-in GPS receiver, so that you can have location information added to metadata for potentially every photo you capture. For cameras without a built-in GPS receiver, you may find that an accessory GPS adapter is available. In addition, you can use a completely separate device to record a GPS track log during a photography outing.

There are a handful of GPS accessories available for various camera models. In some cases you may find that your camera manufacturer offers such an accessory. In addition, there are some compatible devices available from other manufacturers. A couple of examples include Aokatec (http://www.aokatec.com/AK-G.html) and Promote Systems (https://promotesystems.com/products/promote-gps).

If a GPS accessory is not available for your camera model, or if you simply don’t want to use such a device, there are a variety of ways you can record a GPS track log. For example, a variety of smartphone apps are available that enable you to record a track log. In addition, many GPS navigation devices include this feature. The idea is that you can record a GPS track log during the time you are out photographing, and then you can synchronize the track log with your photos using supported software (such as Adobe Lightroom Classic CC) to add GPS location information to the metadata for your photos based on the track log you recorded.

To be sure, the simplest overall solution is to upgrade to a camera with a built-in GPS receiver. A good alternative is to opt for a GPS accessory (if available for your camera) so you can still have location information added automatically. But if this isn’t an option for you (or you want to avoid the additional battery drain caused by the GPS receiver), creating a track log during your photo outings is a great option as well.

Today’s Question: In one of your video lessons on Lightroom I noticed that you only had one section of each panel open at a time, and that when you opened a different section the previously opened section would close. Where is the setting to enable that feature?

Tim’s Quick Answer: The option to have only a single section of a panel open at a time in Lightroom is referred to as “Solo Mode”. You can enable Solo Mode for either panel by right-clicking on an empty area of the panel, and then choosing “Solo Mode” from the popup menu.

More Detail: When Solo Mode is activated for a panel in Lightroom, only one section of that panel will be open (expanded) at a time. When you open a different section on a panel with Solo Mode enabled, the panel that had been opened will close (collapse).

The Solo Mode feature operates independently for each panel (left or right) in each module (such as Library versus Develop). Therefore, you can enable Solo Mode for some panels in some modules, but leave it disabled for others if you prefer.

You can see Solo Mode in action in tip 41 (from April 11, 2018) in my “Lightroom Quick Tips”, which features a new quick tip every single week. This course is available as part of the GreyLearning Ultimate Bundle or the Mastering Lightroom Bundle. In addition, the course can be purchased as a standalone on the GreyLearning website here:

Today’s Question: After reading some of your posts about using a camera with a built-in GPS receiver, I’m giving thought to an upgrade to such a camera. But I’m wondering if there is a clear indication that the camera actually has a GPS signal, so you have some confidence that you really are recording the location information. Do these cameras have such an indication?

Tim’s Quick Answer: Many cameras that include a built-in GPS receiver do indeed provide some form of indication about whether the camera has acquired a good GPS signal.

More Detail: As you can probably imagine, different cameras have different ways of indicating the status of the GPS feature, and some cameras don’t provide any clear indication of the current status.

With digital SLR cameras that include a built-in GPS feature (or the accessory devices available for cameras without a built-in GPS antenna), there is generally an indication on one of the camera’s displays to let you know if the camera has acquired a good GPS signal.

For example, on my primary camera, there is a “GPS” indicator on the top LED display. When the GPS antenna has been activated in the camera’s settings, that indicator flashes. Once a good GPS signal has been acquired, the indicator becomes solid. Other cameras use different indications, but in most cases you will have some indication that you have a reliable GPS signal, and therefore will have accurate location information embedded in the metadata of your photos.

In most cases when the camera does not have a good GPS signal, no location metadata will be added to the images. However, it is worth noting that in some circumstances photos may have outdated (and inaccurate) location information embedded. For example, I’ve had situations where the first few photos I capture at a new location have location metadata from the previous day’s location.

Of course, checking the status of the GPS signal first can help ensure the most accurate location metadata. So, when looking for a camera that includes a built-in GPS receiver, it is a good idea to also take a look at how the GPS signal status is displayed, so you can help ensure the location information in metadata is accurate for all of your photos.

Today’s Question: I have started to use Landscape Pro, which saves back to my Lightroom catalog as a TIFF file. If I then export as a JPEG, do I lose quality doing this? If so, when I want to send a file to a lab for printing and they accept TIFF or JPEG, which would you consider the better choice?

Tim’s Quick Answer: While it is possible to produce an excellent print from a JPEG image, I do recommend opting for a TIFF file when possible. While the impact may be minor, there is always at least a small degree of quality loss when saving an image as a JPEG.

More Detail: A JPEG image always has compression applied to it, and that compression always causes a certain degree of quality loss for the image. At a high quality setting the JPEG compression won’t be especially significant, but there is still a degree of risk that some of the compression artifacts will be visible in the image (and in the final print).

Therefore, to help ensure maximum print quality, I always recommend using a file format that enables you to either not apply compression at all, or to employ lossless compression. The TIFF file format is one such option.

If possible, I recommend using the TIFF format (rather than JPEG) when creating derivative images you will send to a lab for printing. When creating a TIFF file, be sure to either not use compression, or to use LZW or ZIP compression (both of which are lossless compression options).

It is most certainly possible to produce high-quality prints from a JPEG image. However, there is also a risk that a print from a JPEG file will exhibit some degree of visible compression artifacts. So, if possible, I recommend the TIFF file format rather than JPEG when creating a derivative copy of an image for printing.

Today’s Question: I was recently told by a Lightroom guru that when importing images shot in RAW into Lightroom, they actually come in as JPEG images. If that is true, what then is the advantage of shooting in RAW?

Tim’s Quick Answer: Your raw captures are not converted to JPEG images upon import into Lightroom, so you can indeed retain the original raw captures and the benefits those captures provide. The previews of your captures viewed within Lightroom (other than in the Develop module) are JPEG previews, however.

More Detail: It is possible you may have misunderstood what that Lightroom guru was saying (or that they weren’t in fact a guru).

Lightroom does indeed enable you to import (and therefore retain) supported proprietary raw capture formats. The confusion about converting to JPEG probably relates to the previews that Lightroom generates for your images. You can choose, for example, to generate “Standard” previews for all of your images upon import. These are essentially JPEG images that are approximately the size of your monitor display (depending on your Preferences setting and monitor configuration).

The previews Lightroom generates enable you to view your images more quickly in the Library module, and also to view a preview of the image even when the source files are not available, such as when an external hard drive containing your photos is disconnected from the computer. In the Develop module a full preview based on the source image is generated and updated in real time as you apply adjustments.

So, JPEG previews are most certainly created for your images when you import them into Lightroom or view them within the Library module, but those JPEG previews do not replace your original raw captures. The actual source files you imported would still be available. The only other exception to this would be if you converted your proprietary raw captures to the Adobe DNG format during import, but in that case you would still have the DNG version of your image, which is similar in concept (and provides the same quality) as your original raw capture.

Today’s Question: When cropping a photo in Lightroom, one is given the option of “As Shot”, “Original”, or “Custom”. What is the difference between the first two, and when would one use one rather than the other?

Tim’s Quick Answer: The “As Shot” crop option in Lightroom is for supported images from cameras that enable you to choose a crop that differs from the native aspect ratio of the sensor. With such a capture, the “As Shot” option would activate the crop aspect ratio set at the time of capture, and the “Original” option would activate the full image based on the sensor dimensions.

More Detail: For many photographers the “As Shot” and “Original” crop aspect ratio options will produce the exact same result, either because their camera does not offer the option to alter the capture aspect ratio, or because Lightroom is not able to access that information in the metadata for the capture.

When you select an in-camera crop aspect ratio that differs from the full aspect ratio of the sensor, you are of course capturing an image that does not contain all of the available pixels based on the sensor in the camera. With a raw capture, however, that crop setting is just a metadata value, and the full range of pixels available on the sensor will actually be included in the raw capture.

With supported capture formats, Lightroom is able to access the in-camera crop setting, and make that available with the crop tool. So, if you have taken advantage of this option with a camera that is supported for this feature in Lightroom, you can choose whether or not to crop to that aspect ratio setting based on the availability of the “As Shot” crop aspect ratio option in Lightroom.

Today’s Question: I am using latest version of Lightroom Classic. How do I discontinue Import DNG Creation? Under preferences, File Handling, I am unable to disable this feature. Hence, my images are no longer available in Canon Raw. I’m missing something, obviously.

Tim’s Quick Answer: The option to create Adobe DNG (Digital Negative) files upon import is found at the top-center of the Import dialog. Simply choose the “Copy” option (rather than “Copy as DNG”) and your proprietary raw captures will be retained without being converted to DNG.

More Detail: When importing new captures into Lightroom, you’ll generally want to copy your images from their current storage (such as a media card from your camera) to a hard drive. However, there are actually two “copy” options when importing your photos.

At the top-center of the Import dialog you can choose whether you want to copy the photos being imported, move those photos, or simply import from the current location using the “Add” option. When downloading from a media card, of course, you would want to copy the images to a hard drive.

If you prefer to make use of the Adobe DNG format (rather than your camera’s proprietary raw capture format) you can choose the “Copy as DNG” option at the top-center of the Import dialog. Of course, if you don’t want to convert your images to DNG (or you want to import the proprietary raw captures and convert to DNG at a later time) you will want to use the “Copy” option.

So, next time you import photos, you can simply change the import setting from “Copy as DNG” to simply “Copy”, and you’ll be once again copying your proprietary raw capture files without converting them to the Adobe DNG format.

Today’s Question: I often submit images to camera club competitions. I shoot in RAW and only use Photoshop (not Lightroom). I must resize the image and convert the image from PSD to JPEG. Do you think it makes a difference which is done first: resize or conversion?

Tim’s Quick Answer: In concept I would perform the resizing step before saving the image as a JPEG. But in reality I would recommend using the Image Processor feature in Photoshop to help automate this task (even if you are only processing a single image).

More Detail: As noted above, conceptually I would want to resize the image before saving a JPEG copy, rather than saving as a JPEG and then resizing that image. In reality the differences in terms of image quality would be virtually non-existent, especially in the context of an image that will be impacted by the quality loss involved with JPEG compression.

In any event, you can make the overall process of creating JPEG copies of your master images by using the Image Processor feature in Photoshop. You can find this feature on the menu by choosing File > Scripts > Image Processor. However, I recommend using Adobe Bridge to first select your photos. Within Bridge you can then choose Tools > Photoshop > Image Processor to send the selected photos to Photoshop and bring up the Image Processor dialog automatically.

Within the Image Processor dialog you can first select where you want to save the copies of your images that will be created. You can then turn on the “Save as JPEG” checkbox, and turn off the checkboxes for the PSD and TIFF file formats. Below the “Save as JPEG” checkbox you can then set the other options for the JPEG images, including a setting for resizing the images, setting the quality level, and converting to the sRGB color space profile (which I do recommend doing).

Once you’ve established the desired settings in the Image Processor dialog you can click the Run button to process the images you had selected. The resulting files will be saved in the destination folder you specified. Note that if you chose the option to save the images in the same location as the source images, they will actually be saved in a folder by file type (such as “JPEG” in this case).

Today’s Question: Is there a way to use the leveling tool in the crop menu on auto import?

Tim’s Quick Answer: You can have your images automatically rotated (such as to straighten a crooked horizon) during the import process by using a preset that includes the Upright mode set to “Level”.

More Detail: The Crop tool in Lightroom enables you to adjust the rotation of the image to straighten a line that should be perfectly vertical or horizontal, such as a horizon line. There is even an Auto button that enables you to apply the rotation to the image automatically based on image analysis.

As you may have noticed though, you’re not able to save crop settings as part of a preset in the Develop module in Lightroom. That means the leveling feature of the Crop tool can’t be applied as a preset in the Develop module or upon importing new images. You can, however, achieve the same leveling result by creating a preset that includes the Upright Mode option, with the Upright feature set to “Level”.

To create a preset that includes automatic leveling, be sure to first click the “Level” button under the Upright heading in the Transform section of the right panel in the Develop module in Lightroom. Then, when saving a new preset, be sure to turn on the “Upright Mode” checkbox under the Transform checkbox within the New Develop Preset dialog.

If you apply that preset within the Develop module or using the Develop Settings popup in the Apply During Import section of the right panel in the Import dialog, the preset will apply the Upright correction to rotate automatically based on an analysis of the image. Note that you could also apply more sophisticated transformations by using the Vertical or Full options for the Upright adjustment, for example.
