Sony A1 imports are dark in LRC

I have same problem with Sony A1. I was photographing a bird and I said to myself "what beautiful light!" When I opened in RAW entire photo was 1 stop underexposed. (Note My exposure compensation is locked to zero) I looked at the Color space and it was listed as "Camera ST" which is a space I have not seen before. I normally use Adobe RGB. Since I only use Photoshop, Lightroom is not a solution for me. Trying to figure out what menu button I need to fix in the Sony A1. This has only recently started as problem.

Color space has nothing to do with exposure. The color space on the camera has nothing to do with the raw, only the JPEG previews. 

You opened the raw where to see it was 1 stop underexposed? Not in any Adobe product, it has no raw Histogram.

You said, Used my Minolta Flash Meter III for an ambient exosure reading of 15th of a second at F5.6 at ISO 100. If you reduced the light level for the 15th second at F5.6 ISO 800 by -2.0 EV as read on your Minolta Flash Meter III then I agree the two files should be near identical.

No sir. The exposure for both was identical. No sir, there is zero reason to alter the ISO on the meter either. 

The ISO plays zero role here. ISO isn't an attrubute of actual exposure. Exposure is two and only two attributes which control the amount of light striking the sensor: Aperture and Shutter. The ISO makes zero difference here. The two captures have identical exposures as both, repeat both, were 15th of a second at F5.6.

The ISO being set to 100 vs. 800 doesn't alter this whatsoever. 

Setting ISO speed does not change the sensitivity of the sensor to light, like volume control does not change the sensitivity of a radio. In both cases the setting (ISO or volume) controls only the signal processing, while the input stage (sensor, antenna) provides the same input signal.

But when ISO setting is cranked up, automatic exposure results in more noise - automatic exposure in this case decreases the exposure (that is, the combination of aperture and shutter speed is set to allow less light captured by the sensor). Less exposure, less light, more noise. I did not use automatic exposure as I pointed out. 

And further, a higher ISO can produce LESS noise than a lower one, again because it has nothing to do with exposure (when the photographer doesn't allow  automatic exposure):

A better test would be to set your camera for auto exposure (Aperture or shutter priority), set ISO to 800, shoot a picture, and then without changing the lighting set PP7 and shoot the same picture.

 No, it would be another invalid test like the URL provided. PP7 and PPOFF are identical. When everything else is the same (and again, ISO isn't at all a factor here). Had I done as you suggested, the two would differ due to exposure (actual and real exposure) and the test, seeing what PP settings do, alone. Doing as you suggest isn't what the test was about which is to invalidate the URL suggesting, incorrectly, that changing PP settinsg affects the raw. It doesn't. 

I didn't use "Auto Exposure" for exactly the reasons expressed. 

---

I noticed in PP7 and auto ISO pulls down the exposure to create the dark picture (and yes the histogram is showing this prior to the shutter closing). Styles as others have pointed out is not the culprit. Solution is turning off PP since i shoot very little video.

---

Again no! PP7 settings alone, and that IS the test, do nothing at all differently to the raw data. PP7 doesn't affect exposure and RD shows this clearly. PP7 changes the JPEG processed from that IDENTICAL raw from that of PPOFF. Hence the JPEG is again, useless! 

And I thought we both knew; the Histogram is a lie and tells us again, nothing about the raw data or its expsoure. But RawDigger does.

EXECUTIVE SUMMARY

Camera Menu Picture Profile 7 setting underexposes the image file by -2.0 EV.

---

I don't follow you. PP7 doesn't under or over expose anything (on this end). The two images I shot here have identical exposure. The ISO is indeed different. But ISO has nothing to do with actual exposure. 

---

What's strange is the embedded preview with Picture Profile 7 doesn't match exposure or contrast (gamma).

---

Again I'm not following you if your comment has anything to do with my testing. And in some cases it doesn't matter either: the embedded preview has nothing to do with anything other than some raw to JPEG rendering by the camera. It was just wrong and meaningless. The exposure for raw was the exposure for raw; what's the embedded preview got to do with this? 

Solution: PP7 and PPOFF are no different; they don't affect the raw. The video posted is rubbish and worse, the author of it apparently doesn't accept this. That said, there seems to be zero reason to use PP7 or many other settings (and at least for me, it simply mucks with the ISO, which was a pointless setting from the start for raw). I didn't use an ISO to base my settings on exposure. Which is why both raws are identical. 

And a nice video:

I have one; RX10IV and the manual shows:

Standard:
For shooting various scenes with rich gradation and beautiful colors.
Vivid:
The saturation and contrast are heightened for shooting striking images of colorful scenes and subjects such as flowers, spring greenery, blue sky, or ocean views.
Neutral:
The saturation and sharpness are lowered for shooting images in subdued tones. This is also suitable for capturing image material to be modified with a computer.
Clear:
For shooting images in clear tones with limpid colors in highlight, suitable for capturing radiant light.
Deep:
For shooting images with deep and dense colors, suitable for capturing the solid presence of the subject.
Light:
For shooting images with bright and simple colors, suitable for capturing a refreshingly light ambience.
Portrait:
For capturing skin in a soft tone, ideally suited for shooting portraits.
Landscape:
The saturation, contrast, and sharpness are heightened for shooting vivid and crisp scenery. Distant landscapes also stand out more.
Sunset:
For shooting the beautiful red of the setting sun.
Night Scene:
The contrast is lowered for reproducing night scenes.
Autumn leaves:
For shooting autumn scenes, vividly highlighting the reds and yellows of changing leaves.
Black & White:
For shooting images in black and white monotone.
Sepia:
For shooting images in sepia monotone.

First of all I want to thank everyone for the ideas and help, this has been really puzzling for me and the quick response was wonderfull!!!

This was strange as i would inport a file that had images from both my A7R4 and the A1, the A1 were badly underexposed and the A7R4 were good.    As the files were imported that looked fine and then darkened.   They showed to be properaly exposed in camera.    

Todd's suggestion on the picture profile was right on.   In setting up the camera, i had followed a suggestion to use picture profile 7 and when i went to no profile, the problem was corrected.   I will keep it there for now and try to better understand this more later.     

Again thanks everyone for the help!

They are set to none on import, have thought about using them to add light back  in or do it in Synch, but would like to understand the true problem and not to workaround.   The preset setting is Adobe defualt, as Sony A1 is not listed as an available camera.    I have talked to 2 other A1 shooters and they do not have any issues, so something must have changed.
