I am still holding out for Keurig support. Sorry, but that is a deal-breaker for me.

A new line of instant film cameras with film that has a sticky back so you can put the photos on the wall.

Introducing.... "Pentacks"

Well, thank you, Mike :) I try to find new ways to capture this everyday scene.

Yup, the one and only. That roll was just me experimenting with it and I didn't get a lot of good results. Now I have a vision as to how to use it.

Anywho, more:

Photo taken by my father, Walther Kraus, in Olympia, Greece in 1928 (9x12cm negative copied with K-1 and smc Pentax-DFA Macro 50mm f/2.8).

and you know so many folks would learn about their photography a hell of a lot quicker if they followed the same routine from the get-go. But persuading someone who has just shelled out hundreds or thousands on their first camera, to use it in manual mode and dont look at the meter.....well forget it !

Luminance versus RGB histogram, and the fact that a different set of development parameters (Lightroom default versus your camera settings) being applied to the raw image will both affect the shape and spread of the histogram.

Another option is to get your Pentax Digital Camera Utility software (or anything else - eg DxO Optics pro) to open the RAW, and compare it with what Lightroom is doing. It might help you figure out what's going on.

When you're importing it's probably showing the embedded jpg from the raw, and once it's done importing it looks at the raw data and applies a default profile. What you're describing sounds exactly like the highlight correction effect, so you might want to double check that it's still turned off.

It could also be that your default profile in Lightroom changed. Try adjusting a picture to a standard profile or no correction to see if that's the case. (Not sure the exact buttons on Lightroom but in DXO you right click the image and select "no corrections" it will show the raw image as shot with only your in camera settings applied.)

If you can't figure it out try shooting in raw+jpeg. If the jpg is underexposed too then it's either a camera setting or camera error and you can try doing a factory reset.

Be aware that the JPEG brightness and contrast settings may influence the in-camera histogram. I don't have a K-50 at hand, but know this is the case for my K-3. Again, the histograms for both the camera and Lightroom represent the processed image's brightness distribution. They do not represent the camera's exposure meter reading or the base sensor response.

Yes, I know. This is a bit problematic, particularly if one is doing ETTR or some other histogram-dependent exposure scheme, but that is how it is. The histogram is never based on the RAW sensor response. White/highlight clipping is always a combination the actual exposure plus downstream image processing and quite legitimately so is the histogram.

My practice is to routinely use the "natural" custom image setting for RAW capture. Doing so provides a histogram that is generally representative of the subject as seen by the eye.

Are you importing both JPG and DNG versions of the same image into LR, and, if so, do they look similar to each other, or do their exposures, and LR histograms, also vary between each other?

Check if you have highlight correction enabled. On mh K-3 it causes a similar effect where the jpg looks fine but the raw data is underexposed when loaded in DXO.

Highlight correction underexposes about a stop to keep from blowing highlights and corrects it in camera when making the jpg. The jpg thumbnail included in the raw file is also corrected but opening it in a raw editor shows the underexposed raw data. Boosting by 1 to 1.5 stops should fix it, or turn off highlight correction on your camera. (If the K-50 doesn't have highlight correction you can just ignore what I've said.)

I'm a fan of the natural setting too. It looks the closest to what I see and remember in my mind. Bright seems to overemphasize reds and oranges in skin and wood tones.

I wonder if it displays the processed version's thumbnail but shows the histogram based on the unadjusted raw data?

This recently happened to me with my K3. Turned out I had inadvertently bumped the exposure compensation button on the camera. The images looked correct on the camera screen, but when I uploaded them, I had to bump the exposure by 1.5 stops to get it correct.

Conjecture: Lightroom might be correct. The photo is underexposed, but the camera LCD brightness is cranked too high so you don't notice it. That's a different camera setting than the color profile.

Look at the bottom line of the K-50 photo display: 1/2000, F--, ISO 100. The F-- suggests you are using a manual lens. What aperture did you use, and what were the lighting conditions? We can calculate backwards and estimate if 1/2000 shutter would create underexposure.

This is pretty much the rule. The in-camera histogram is based on the preview JPEG, which in turn reflects the JPEG image settings. Lightroom's, OTOH, is based on its RAW conversion as modified by the import profile and whatever settings applied in PP.



What import profile are you using? If other than Adobe Standard, you might want to switch to that.



Those profiles only apply to in-camera JPEG, in-camera RAW conversion, in-camera image review (JPEG and RAW), and RAW conversion using the Pentax software that came with your camera. In other words, proprietary Pentax stuff. Lightroom does not have the means to reproduce them for RAW conversion* and simply ignores them.


Steve

* This is generally the case, though Lightroom does have Pentax-provided import profiles that correspond to several of the custom image settings for several cameras. I don't remember if those include the K-30/K-50 models.

SMC-K 55mm f1.8 at f2.8 .

I'm always on the look out to add to my collection.
I was trying to decide between the 30 f2.8 and the 85 f1.8, until everyone started posting with the 28 f3.5, and the 35 f2.
Now I have to add to my searches.
