Ever since I've got my D300s when I bring photos into Lightroom (2.7) it automatically adjusts the exposure. It briefly shows the image as I took it and saw it on my LCD, but then a second later the exposure changes. I like to live on the edge, so it's usually bumping my exposure to being blown out. I've been meaning to look up why it's doing this, but haven't found the time. Can anyone save me time and explain why it's doing this?
My theories are:
- Some setting in Lightroom
- Camera firmware |

| The key is that Lightroom knows you are shooting with a different camera, and Lightroom's default processing settings can be saved separately for each camera. Set them to what you want them to be, and save them as the default setting for the camera, and you are set to go! |

Hmm, can't say I've ever set up a preset by camera. Here's a screenshot of my preset preference. If it were making those changes automatically thinking I was still using my D80, wouldn't the "make defaults specific to camera serial number" be selected?

Not quite.
What aliqui is seeing is that when the file is first imported, LR uses the preview JPEG that is embedded in the RAW file. After LR generates it's own preview, the image changes to LR defaults. LR doesn't apply camera specific settings like sharpness, saturation, etc.

Well, perhaps my statement was incomplete. Lr *can* approximate (note approximate) the in-camera settings, if you load profiles specific to your camera. But that's another subject.
The key here is that she sees different or unexpected behavior with the new camera. She needs to set it up how she wants it, then lock it down for that camera by saving it as default settings, which are always specific to the camera. So whether or not she had previously saved default settings, this is what she needs to do to accomplish her goal.

Actually AlohaDave hit the nail on the head - I see the issue that the OP mentioned whenever I import files from my 5D - initially when viewing the images as they import (generally in grid view) they look very similar to the image I get on the LCD of the 5D, this is a result of LR using the small embedded JPGs to quickly display a thumbnail - however after a few seconds it changes to a more neutral look in Grid view as LR generates thumbnails based on the RAW and using the LR engine. Unless shooting in JPG the only setting that can really be imported into Lightroom is the whitebalance, and then only as long as you choose the "As shot" preset. Data in the EXIF such as the exposure preference chosen at time of shooting (+1/3 +2/3 etc.) is retained in the EXIF, and will be displayed if you ask for LR to display that info, but that doesnt translate to automatically pushing the exposure slider up in LR. Unless this is something specific to Nikons, but never heard of it myself. |

Yes, abaolutely, the initial preview is due to the embedded JPEG, which of course exactly reflects the camera presets. For the RAW data, however, even the WB setting is an approximation on import, *unless* you apply the same camera profile to the RAW as was applied to the JPEG. Lr profiles are available for some cameras, and can be created from scratch if you know how.
Exposure compensation is never something that you'd want applied "as shot" since physical exposure (and thus the RAW data) was already compensated for it; if you re-applied it, you'd be compensating twice.
So my original advice still stands... if you want to be able to duplicate out-of camera JPEGs (I almost never do, FWIW) then install camera-specific profiles. If you just want a reliable starting point, set your personal preferences and save the settings as default for camera.
What I usually do is to set WB to "As shot" so I am in the ballpark, then tweak later. Either I've shot a gray card and can set based on that for a series, or I manually tweak one of the series and copy/paste the setting. I lock the exposure at zero, and set a conservative sharpening setting (Amt = 50, Radius = 0.6, Detail = 0) that will work for the highest detail images (I can always crank it up if needed). I apply no NR by default, again I can introduce it as needed.
In most cases, the default settings get me close, but I am still tweaking each series shot in the same lighting conditions to optimize color rendition, and each image gets its own adjustment for exposure. |

| Thanks guys. I haven't had a chance to really read (understand) and experiment with what you're saying, but hopefully in the next couple days I'll get some time. |
