Lightroom :: How To Increase Exposure By 1 Or 2 F-stops For HDR
Mar 21, 2013
My goal is to:
1) Take an existing picture.
2) Make two more copies of it.
3) Alter the exposure compensation of the copies by either exactly 1 or 2 stops up or down as needed.
4) Merge those shots to form a quasi-HDR composite image.
When I open the master/source picture in Lightroom, how do I change the exposure by exactly one or two stops leaving all of the other settings untouched?
Yes, I know the master exposure slider goes up to 5.00, but what exactly do those values mean if anything in direct correlation to f-stop's? Is it accurate? how changing the exposure is executed.
Why when Lightroom loads images (in develop module), all images turns gray and dark (the preview looks fine - expected exposure and full of colour). All settings are on 0, no auto tuning or presets are applied.
Also, when I take pictures (Nikon D4), they looks fine in my back screen and I would guess D4 knows how to calculate exposure. But in Lightroom they all come out at least 1 full stop unexposed, so after adjusting exposure I got unnecessary noise grain (and work).
I even tried to upload thought Nikon View NX (soft for Nikon transfers) first, as I was hoping that after importing files to Lightrooms I will also get camera colour settings (like Landscape, Portrait, Vivid, etc.).
This is screenshoot - when Lightroom loads/process all images they all turn so dark as selected image. Neighboring sunflowers all were the same, and they was as I expected them to be.. Before they turn dark...
I am getting an Error message stating "There was an error calculating the effective exposure for the target photo. No photos were changed. The files are jpegs. Is this an issue? I have been successful using this Develop feature on a few files, also jpegs, but more often than not, I am getting this error message. The selected file has an exposure adjustment done in the Develop module. Does MTE only work when the originals are significantly different in their original exposure?
I don't see it listed in the metadata options although LR knows it exists. (I don't see metering mode either) Is exposure bias really not a filter option?
When I send photos to photoshop, they come back to Lightroom noticeably lighter even If I don't edit the picture in Photoshop. I'm using Lightroom 4.2, Photoshop CS6, images are RAW, and OS is Windows 8.
I have no presets marked to run(that I know of), and my raw images look great, but the first time I look at them individually, they change a full stop brighter... What is going on! I correctly expose each image and am having to overhaul them in LR.
As most of you probably know, Lightroom cannot properly deal with Nikon's Active Delighting -- it just "ignores" the information, whereas vendor specific software interprets that information. Since vendor specific information can later on redo the ADL development process which usually happens inside the camera the necessary information must somewhere be preserved.
Most metadata-editors know settings like ADL off, moderate, high, etc. But that cannot be all there is. I noticed that my D7000 varies the under-exposure (1/3 EV -> 1 EV) in the same ADL-setting. What I'm looking for is exactly that amount of under-exposure (or a value from which I can derive that).
How do I get the my exposure option back to my + and - keys?
Normally I can quicky change my exposure with the + and - keys, but now it only changes my clarity in stead of my exposure. How can I change it back to my + / - key on the keyboard?
It seems that even with a calibrated screen and across multiple print labs and colour profiles, my prints will always come out about a third stop darker than what looked good on the screen. I attribute this to the screen emitting light vs. the page only reflecting it. My question: is there an efficient way to give an equal exposure boost across an entire shoot? I don't want to sync a specific exposure setting. I want to make virtual copies for print and then add maybe 0.3 exposure to all files, on top of their current setting.
The only way I can think do to it now is to export 16-bit tiffs which will reset the exposure to 0.00 for those files, and then sync them all at +0.3 exposure. This is really inefficient for time and hard drive space. Even a preset will only set a specific overall exposure setting. I want a preset that adds exposure to the existing number.
I have a group of about 500 images I took yesterday. I want to find all images out of that group that have a certain exposure compensation (exposure bias). I am trying to create a smart collection of these but am seeming to have problems doing so. I have set up the following criteria: Date = 2013-31-13; and Searchable EXIF = 1/3. I've tried other variations. The best I can do is get 17 images put into the smart collection, but only some of them have an Exposure Bias of 1/3; others have a bias of 0. I know I have quite a few more with exposure bias of 1/3.
How can I do this....again, I want to find all images with a certain exposure bias, either 0, 1/3, or 2/3.
When I select Brush, changing the exposure supposed to change only the selected part exposure. In my LR-5 it changes the whole image exposure. What am I doing wrong?
I have been trying to create a preset that updates the Process Version to 2012, changes contrast, highlights and shadows, but leaves the Exposure unchanged.
So, I change the Process Version to 2012, set the sliders for contrast, highlights and shadows where I want, and then I create the preset, leaving Exposure (and a bunch of other things) unchecked.
Then, I apply the preset to a photo that is currently Process Version 2010. The process version, contrast, highlights and shadows all change as expected, but the Exposure goes to zero.
I will be shooting a series of photos that inludes a gray card in each image. How can I use Lightroom to obtain the same exposure in each image relative to the gray card?
In Lightroom 3 when you moved through images these modify keys (+ and -) would always remain at the temperature slider. It seems to now always default to exposure. Is there anyway you can change this?
I'm trying to fix the exposure on the TV screen using the brush tool, and it's not doing the job at all. Even with multiple overlays of adjustments it's not changing the exposure nearly enough, and you really can't see the game at all. The white areas of the image on the screen are remaining that way and the rest is just slightly darker and becoming less saturated as well.
I thought maybe LR was just not up to such a radical adjustment and that I need to use Photoshop (which I don't own), but then I tried changing the exposure on the whole photo, and taking it down to zero made an enormous difference on the TV screen, which turned out at the correct exposure, well saturated, with only a little loss of data. This tells me that the data is there in the image--so why can't I get it locally with the brush tool?
After that I tried leaving the whole image underexposed and then using the brush tool to increase the exposure everywhere but the TV screen, but it stayed pretty dark.
I want to increase the exposure of a batch of photos by one quarter of a stop.The Quick Develop module seems to allow only one third increments.Can I change this? The Sync function matches absolute exposure. So apparently do all the presets.I see that there is a third party plug in that may do this, but is there no way to do it in Lightroom 4?
I get artifacts when I lighten (dark specks) or darken (white specks) when I use the adjustment brush to adjust exposure on my photos. It would seem to be a big enough bug to get noticed and promptly fixed, unless I am doing something wrong.
Is there a way to specify the begin and end exposure adjustment on the gradient tool?
What I really want to do is apply an even exposure adjustment to the bottom section of an image. There's a hard line where I want the adjustment to begin, so I don't really need a gradient. I know I can do this with the adjustment, but that requires passing the brush over a large section of the image and, of course, being very careful in lining the edge of the brush up with the edge of what I want to lighten. I'd like to be able to put a line across the image and say "lighten everything below this line" by x amount.
I have a batch of photos that are adjusted individually for exposure. Now I want to increase the exposure to all of them by say. .10 stop. Is there a way to do this in LR4 without having to adjust each file individually?
when importing photos (raw files) to Lightroom they look very different than in the camera. At the very beginning photo looks more or less the same and then, a message „Loading…” is displayed and in a result the photo looks differently. It looks like with imposed dimmer yellow/red filter, higher contrast, much lower sharpness and what is most important, they are all overexposed sort of. The screen settings are as sRGB, ICC profile: sRGB IEC61966-2.1. I am using DSLR Sony A700 that save photos in ARW format, Lightorrom just updated to version 4.3 .
I have been using Lr 5.3 to adjust some RAW images. My Develope pane is now missing the pane for White balance, hue and also the pane for Exposure, Contrast, highlights etc adjustments. I don't know how this happened or how to restore them. I am using iMac.
Is exposure and contrast supposed to be altering saturation in version 2012? See the 4 screen shots below to see what I'm talking about (RAW NEF taken with a Nikon D4 and the other details are on the screen). Here I am adjusting effects contrast, but I don't think it matters which contrast.
v2012 contrast set one way (this slightly peach tone is accurate and desired):
v2012 contrast raised. There is no mistaking how much yellower it is. Now if I try to fix this with the color controls, something else usually gets thrown off.
This does not happen in v2010: Contrast raised (if anything, slightly opposite):Do not get me wrong --the 2012 controls are far superior at their named function --but they make the mistake of doing more than that function.
The fundamental problem here is that this makes it extremely difficult to edit a photo because changing one setting alters settings you may have already set. When order in which you tweak things becomes a factor, it exponentially increases the complexity (and edit time) because you are then dealing with a moving target. You keep having to go back and reset settings that should not be drifting, and did not drift in prior releases. This is a problem for me especially with photos containing a wide range between light and dark, especially where contrast is desired in both light and dark (as above). This is not the first contrast control problem I've posted (it appears to interfere with lens correction). Contrast seems to be at the center of all my release difficulty (that combined with lack of a linear brightness control). Contrast appears to be adjusting more than just contrast in v2012.
Lightroom stops importing, the progress bar stops moving. After quiting Lightroom and trying to sync the folder it happens again. There are no strange fileformats in the folder, just straight JPG and XMP. This is pretty annoying - such a basic functionality should work out of the box.
I've read that the german character "ß" could be the cause (so every file tagged with German Street Names in it will stop LR from working! Excellent.) – and the release candidate 5.2 should fix the issue. BUT: I am not very fond of installing a release candidate; what happens later, when the final version is released? Does the automatic update function its job? Or do i have to fiddle once more to get the final version working?
