Setting a White Point and Black Point

I would like to suggest for future versions of lIghtroom to have an ability to set the white point and black points similar to levels and curves in Photoshop. This would be in addition to setting middle grey in the white balance settings currently in Lightroom. I find that the method of using Threshold to find the closest white and black pixels and then using these points to set the black and white points in curves or levels provides a better way to fix a color cast than the methods available in Lightroom.

MB,
There is no real need for Black and White point eyedropper type tools in Lightroom. By holding down the Alt key while changing the Blacks or Exposure sliders the display will show the areas that are being clipped. This is much faster than looking around for the darkest and lightest areas manually. If you just like to click to taste (like using the White balance dropper) then forget the Alt key and just move the sliders until you get the desired look.
Remember that the problem with Photoshop is that there are so many ways to do the same thing that it has become difficult and bloated. Lightroom strives to keep the interface as clear as possible.

Setting White, Mid and Black Points in Camera Raw 7

I am using Camera Raw 7 and can not seem to locate where can you set the white, mid, and black points in Camera Raw with the eyedropper tool. It seems you have to create a new psd file in Photoshop to do this, which does not make much sense since it is a basic levels adjustment. I am batch editing a bunch of CR2 files, and I just need to select the black, mid and white points on a grayscale that I've shot in the images - is there a way to do this in Camera Raw 7? Thanks!!

ACR doesn’t work that way. There is an eyedropper for the overall white-balance that you can set by clicking on a relatively bright, neutral area, but there aren’t black and white-point eyedroppers. But, what is clipped black or white is determined by the output colorspace you have set at the bottom and you can get some idea of what will be clipped black and white by turning on the clipping indicators and watching for the areas you’d be eye-droppering on (the black and white patches in your grayscale) to start showing the clipping color overlay for black and white, but any further toning adjustments will move data in and out of what is darker than black and lighter than white so what is clipped for output will change as you fiddle with the various toning sliders.
The reason things are different: In PS, when you set a black-point and white-point in Levels and click Ok, the data below and above those is thrown away and that is the starting point for the next adjustment. In ACR, things are non-destructive and all the adjustments occur simultaneously, rather than sequentially as in PS, and no clipping occurs until you create the output file. This means that the pixels that are darker than your black-point and lighter than your white-point are still there, and can be moved into the black-to-white range if you do further toning adjustments. Having more headroom of the pixels that are outside the black-to-white range is good because you won’t get the posterization or banding that occurs when colors and levels are clipped after each adjustment in PS.
Can you describe what you intend your overall workflow to be on an image: how much adjusting will occur in ACR and how much, if any, might happen in PS, after the image is opened into PS from ACR, or opened from a file saved from ACR? There might be other ways to approach what you’re trying to accomplish.

Setting the white point and gamma

I've heard that when calibrating your display you should set the white point and gamma to native. What is the difference between setting the white point at 65k and the gamma at 2.2?
Thanks in advance for your time
Rick

The difference would depend on what the native points were to begin with.

IPad Air gets suddenly white screen and black apple

When I am working, my iPad Air gets suddenly (one or two times per week) white screen and black apple screen for a few seconds before I get back the control, anyone has the same problem?

It could be an OS issue but I would not bet on it. I just had a similar case myself (but white apple on black screen) on two unconnected devices almost simultaneously - both on an iPad and on an iPod touch. It is possible that there is something different going on here, perhaps at Apple's servers.
It could of course also just be a coincidence.

When I download a PDF, a user manual for instance, the page is black and the font is green, how do I change this to a white page and black script?

Try opening it with Adobe Acrobat Reader.
Note: Appleworks is the Apple office like application that stopped being able to run with Mac OS X 10.6.8. If you have a question particular to 10.9, I would ask in the 10.9 (OS X Mavericks) forum.

Shortcuts for whites, neutrals and blacks in selective color

I’d like to be able to assign Shortcuts to Whites, Neutrals and Blacks in the Selective Color dialog because I find the maintained (since CS4) necessity of manually selecting those a nuisance.
Or am I overlooking an existing opportunity to achieve that?

Photoshop CS5:
Alt+9 gives "Whites" but no sign of "Neutrals" and "Blacks"

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Ipad mini froze during ios 8.3 can't do anything frozen on apple screen now has white background and black apple can anyone help

I have an ipad mini ran the ios 8.3 update all going fine then on the last part it decided to freeze on the apple logo screen. The screen has changed colour, the screen is white and the apple logo is black now. I cannot do anything with it, I tried to restore through iTunes but nothing happens. I tried to connect to iTunes holding down the home key but that didn't work. Anyone have any other suggestions.

Try to reset the device:
Device Reset (won't affect settings/data/music/apps/etc)
1. Press and hold (& continue to hold) BOTH the Sleep/Wake button & the Home button.
2. Continue to hold BOTH (ignoring any other messages that may show) until you see the Apple logo on the screen.
3. Release BOTH buttons when you see the Apple logo and allow the device to boot normally.

Logic reads my keyboards white keys and black keys and vice versa

Logic is reading my Alesis Photon25 keyboard wrong. Pressing the white keys on my keyboard result in the black keys being activated in the transport window. For example, pressing C4 registers as C#4, and pressing C#4 registers as D4. Is there a way to solve this? Thank you in advance.

Try it in Garageband. If it does the same thing, then you've changed a transposition value within the keyboard.
If it only happens within Logic, check to see you haven't got any transposition values with the environments click&ports layer, and on any MIDI thru parameters.

Difference in white iphone and black iphone

Does anyone know what the small black area at the top of the white iphone is and why it is not on the black model?

You can see the same area on the black iPhone if you shine a light at it. It is the proximity sensor to let the phone know when you hold it up to your face.

Setting black and white points

Dear friends,
I am shooting some pics with a "Whibal like" target card which has a white, black and 18% neutral grey shades.
In Camera Raw I I can easily correct the white balance with the provided eyedropper on the top row by clicking on the grey target.
I cannot find any way to set the black and the white points though and have to resort doing that for EACH picture in Photoshop via a levels or a curves adjustment layers.
It would be great to be able to set those in Bridge/Camera Raw so that I can then copy those settings to other similar shots.
Any ideas ? Thank you
Marco
