ACR Blacks slider problem?

Hi
When i use the "Blacks" slider in ACR the darkest parts of the image "block up" and look very noisy. Unlike setting the black point or creating shadow clipping with the levels tool in PS, which gives a smooth effect, the black slider in camera raw seems to make the shadows crunchy and often with red pixels around the black ones.
I use both PS5 and PS6 and on both programs i have the same "problem". I also have used ACR 6.2, 6.7, 7.0 and 7.2. All with the same effect.
Up to ACR 7.0 the blacks slider had a range of 0-100 with the default being 5, and from 7.0 onward the slider can be set to either a plus or minus figure. In either version the default value often makes my shadows look pretty awful on screen. My question is - is this normal? In every book i read it says the blacks slider can be used ruthlessly to sett he black point but if i do that it creates a pretty blocked up result compared to the Levels black slider in PS.
I shoot with a Canon EOS 5d mk2 and the RAW files appear to have quite noisy shadows when compared to the out of camera Jpegs which have silky smooth ones. Not sure if that is part of the problem?

You have several issues swirling around...first off, the old Blacks slider in Process Version 2003/2010 is completely different than Process Version 2012. Yes, any Blacks moves in the earlier process versions tended to really clamp the Blacks...that is now considerably different in the new PV 2012.
So, which do you want to learn how to use?
The Blacks slider of PV 2012 is prolly the last slider you want to use in the tone controls in the Basic panel. If you use it too early, you are not taking an optimal approach to tone mapping. There are plenty of tutorial (Adobe TV) to learn how to use the PV 2012 adjustments...if you learn how to use PV 2012, I suspect your clamped Blacks issue will go away.
As far as the noise in the shadows, the camera JPGs get a dose of noise reduction in-camera. In ACR/LR, luminance noise reduction is set to zero (no luminance noise reduction at all). This would explain why your JPGs seem smoother than the default rendering in ACR/LR. I suggest learning how to adjust the luminance noise reduction in ACR/LR to optimize the noise in your raw captures. Some decent tutorials out there for that too...

Blacks Slider Problem!

Hey,
I shoot with a Nikon D300s and use lightroom to process my images. I was recently trying some grided portraits where I was exposing the model's face and letting everything in the background go pure black. I chimped a lot and also confirmed that the background was truly black, by zooming in so I can see just the background, then using the RGBL histograms to make sure they all read 0. However, when I opened the RAW images in Lightroom and pulled the blacks slider that defaults to 5, back to 0, the histogram miraculously showed no clipping in the shadows and my background was now a murky gray. Does this mean that lightroom is actually pulling detail out of the RAW, or is it just shifting the blacks to ~90% gray.
My light meter told me, that in several of my shots, the background was almost 6 stops or more underexposed, which to my knowledge translates to pure black, where the sensor is picking up no light and hence no detail. I hope someone here can clarify my doubt and tell me if I am missing something or doing something.In fact I took and image at f8.0 1/250th with the lens cap on and Lightroom still pulled back "something from nothing". 'Black' @ 5 gave me R:0 G:0 B:0, where 'Blacks' @ 0 gave me R:5 G:2 B:3. Could someone please explain what the issue is here?

As already mentioned camera histogram displays are created using a JPEG processed RAW image, so not a good indicator of the RAW data!
Download a copy of RAWnalyze 2.10.4.0 to view your RAW images "in the raw" and determine your camera's black levels.

You may also be interested in using UniWB:
http://www.malch.com/nikon/UniWB.html
By trying to expose for deeper blacks you are actually doing the opposite of UniWB! The objective of UniWB is to use the maxium signal highlight range of your camera when determing exposure settings. This lowers noise in the shadow areas, especially at higher ISO settings. How you set the Black slider and tone adjustments to "crush" blacks is up to you!

ACR - exposure slider

I notice when I use the exposure slider in ACR and back off when I see just the initial red clipping my image is way way over exposed... Anyone else experience this problem?

The clipping highlights are only an indication. Your best exposure will probably have some elements of red and blue; so trust your own eyes.
Use the recovery slider and black slider if necessary.
The vibrance slider is also useful - it will enhance subtle colors (e.g. sky and leaves in a landscape) without blowing out more saturated colors e.g. (red and orange flowers)
Have a play around with all the sliders and experiment - no permanent changes are made to raw files or jpegs in ACR.

How can I remove the black slide?

I created a slide show in iPhoto and saved it as a movie, .mov
Apparently in the conversion, a black slide was created at the beginning. This slide is not visible in iPhoto, but it is in .mov and MPEG-4
Does anyone know how to remove that black slide?
Thanks,
Jeanie

Jeanie:
Do you have Quicktime Pro? If so you can move the play head arrows in Quicktime Player to each side of the black frame and cut it out. If you don't have QT Pro try it anyway with QT Player. It might allow that type of editing. Otherwise try using iMovie to trim the black start frame off.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier versions) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. There are versions that are compatible with iPhoto 5, 6, 7 and 8 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
NOTE: The new rebuild option in iPhoto 09 (v. 8.0.2), Rebuild the iPhoto Library Database from automatic backup" makes this tip obsolete.

Blacks Slider

Just spent a couple of hours investigating the new develop module in a bit more detail. I've been trying to simulate my LR3 presets (both colour and black and white) using the LR4b 2012 process. Here are some thoughts:
1. The new process certainly has it's strengths.
2. It's a much bigger change, both in terms of how you apply adjustments and the underlying code than the 2003 to 2010 change. I could update most 2003 edits to 2010 with only barely visible perceptual differences. Not so with 2010-2012.
3. There seems to be much more localised adjustment going on in LR4b. It's hard to quantify, and I certainly see the power of it, but it's possible to end up with an image that looks 'over-processed' much more easily then in LR3. Specifically:
- Adjustments rarely seem to apply in a linear fashion. Obviously the sliders target different points of the histogram/image, but the response seems not to be linear.
- While the highlight tool in LR3 used to pull back the highlights, used in larger amounts it could be used to flatten the lighting image overall. I have yet to find an analogue for this in LR4b. Reducing the contrast slider has a different effect as does clarity. The closest thing is reducing the whites but the effect is somewhat different.
4. In b&w editing the blacks slider has an excessively limited range. I am bottoming out while trying to add sufficient black levels to well exposed images. This is a big problem for me as I like to produce deep rich b/w images. I never got NEAR the top of the blacks slider in LR3 but am bottoming the LR4b blacks out at -100 and wanting more from time to time.
Thoughts welcome!

You don't have to update your existing photos - in fact, I'd suggest not doing so unless you want to reprocess. Leave them on PV2010 and when you come to a photo that you want to use the new sliders on, then you reprocess. It's a completely different process so there isn't a simple one-button-upgrade as there was for 2003-2010.
Yes, the new sliders are image-adaptive rather than linear. Just be gentle with them.
For your B&W's, try the Tone Curve and see how that does for you.

Inserting Black Slide With No Music

Using iWork08, I opened a PowerPoint (PP) presentation and saved it in Keynote 08 (KN).
When running presentation in PP it is possible to have the first slide BLACK with no music, make a few comments, and when I want to proceed just hit the return key and the presentation continues with music.
In KN the presentation plays music with the first BLACK slide. If I turn music off, it turns it off for the remainder of the presentation. Is there a way to insert a BLACK slide at the beginning of KN with no music and have music commence with the second slide forward?
jzach52

Given the way that the current version of Keynote deals with audio tracks, what you are trying to do is not possible - directly. There are a couple of workarounds I could suggest, but both are rather cumbersome:
1) Determine how much time you need for your opening comments under the black slide and when Recording the Soundtrack, include that much silence at the head of the audio track before the music starts; have the first "real" slide begin with the music.
2) Create a silent, black slideshow: one single black slide with no audio. Then Hyperlink the end of this to the first slide in your regular presentation. This will allow you to have as much time as you need for the introductory comments.
CAVEAT: The slideshow will NOT retain any of your Recorded Synchronization when played back via a hyperlink. You will need to advance all of your Builds and Transitions manually. Thus, this is not likely a solution to your problem if you want your slideshow to playback fully automatically.

How to How to install ATI Radeon HD2600 driver on bootcamp 3.0 windows 7 partition w/black screen problem

Ok....so i've posted this question in a different way, and i gotten several "scratch the surface" answers from people just saying to install "Ati catalyst", or insert the os x dvd and run set up.exe, and update to boot camp 3.1 or 3.2...while these all seem like great suggestions, I am finding myself needing more specific direction or "hand holding" so to speak.....here is the MAIN problem...
The Background/history
I used boot camp (3.0, and i found updates for 3.1 for imac and for windows, but can't find for mac pro, AND they all are ".exe" files which run on windows..which as you'll see is the big part of my problem...So I recently updated my mac pro (with the ATI Radeon HD2600 graphic PCIe card with 10.6.7 from 10.5.8. I created a single partitioned drive to install windows 7 professional 64 bit. The download software function didn't work (Thanks, APPLE for that poor level of support) so have to select the option that i have already downloaded, or have other media with the drivers already on it....i restarted with the windows 7 disk in....
The installation of Windows 7 Pro 64-bit
So the installation of windows 7 seemed to go flawlessly, was able to use my existing 23" hd apple cinema display (so somehow it has drivers that work with the graphics card, or maybe the motherboard's on board video components) and i select english, and install now, custom, blah, blah, blah...installation causes a few reboots, then restarts ultimately back in os x since that is the default boot os i use on this desk top and have to do the "opt" button to select booting in windows....so when i try restarting in windows, now using the actual boot drive on which i am installing it, it ran through another reboot or two, but then after that, my display goes black.... in the communities, the solution sounds super simple... "go download the ATI catalyst for the black screen problem....windows 7 doesn't have device drivers that work with the ATI radeon hd2600...no problem, just go download and install...."
The problem, re-emphasized : I cannot even finish the install for windows, because of this driver problem....i cannot see anything....I have tried to reboot in safe mode, and that then seems to invoke whatever basic drivers that do work, likely through the motherboards onboard video vs the actual graphic card, and the screen works and says that it's wanting to complete the installation, so i'm thinking awesome this is gonna work....and then.. "windows installation was not completed and cannot be completed in SAFE MODE, need to restart, blah, blah, blah" pops up...and forces reboot...so Safe Mode allows me to see, but won't allow me to finish the install of windows 7...and without completing the install i can't run (ranther I DONT KNOW HOW TO) any of the various .exe files everyone is telling me are the solutions to my problem...like update 3.1 and 3.2 bootcamp...they're all .exe files? not sure why, because bootcamp runs in 10.6.7 i thought, but whatever...it needs running Windows to execute...then the ATI radeon hd2600 driver for windows 7 that i downloaded from the site has an installation program that is an .exe file, which needs windows to run... Does this make sense, why i can't just use these fixes, that seem to be the only fixes out there....so can someone school me step by step here (not just the highlights) of how to update bootcamp, and how to install the ati radeon driver without having been able to complete the windows 7 installation because the monitor goes and stays black????
This is so very frustrating for the record...and any substantial help "not just go download this..." would be immensely appreciated.
Some other things i've been told to try that i've tried and nothing seems to happen as i'm told it will....
---I've been told to install the osx dvd and run "setup.exe" - AGAIN...it's an exe file...and 2 - when i put in the os x file it just wants to re install 10.6...so need more help if this is even a real solution to understand how to make it work...
---I've been told to update boot camp to 3.1 and/or 3.2 from 3.0, using Apple Software Update....Well, my software update is saying everything is up to date and there is nothing new to download at all, and when i reverify the bootcamp version it is still only 3.0.2...and again downloading the updates from www.apple.com/support/ for 3.1 and 3.2...all of those are .exe files...need windows to run them...again, refer to the problem described in detail above...
---I've been referred to the black screen on imac early 2011 thread saying it should fix my problem...and reading it it SEEMED like the most promising resolution...it involves creating a boot flash drive for windows 7 and an xml file that sets the imac drivers to auto install during the windows installation..and it got me farther than anything else..but still ultimately ended up in the darned black screen...my assumption is that it's because it's for imac and not mac pro so not ati-radeon specific drivers....ok....that's enough..please...anyone who thinks they can help...your help is desperately needed...thanks so much in advance!

hey Hatter, thanks so much for getting back...so just to be super clear...is there no way to install the drivers using an exe file given my current state? no way to do it with command prompt or something? if can make work with existing card, i'd prefer it...now when you say it's 'toast' how do you mean? it works well with the os x partitions and always has...so i'm not sure i follow, just want to be clear...
Now to your point of starting with only the one drive installed...so i would put that bootcamp drive in bay 1 and disconnect the rest...i'm not totally sure what you're suggesting the effect should be of doing this? just that i'm just installing windows without the bootcamp deal...but if windows 7 doesn't support the ati radeon hd2600, it still will go black screen no? or you're saying it will run video through the motherboard if it's the only bootdrive, and will run all the way through the windows install without trying to switch over to the hd2600? (slrry flr these questions..just really want to make sure i understand what you're telling me..thanks so much for your patience and help by the way...it's very greatly appreciated...your support is priceless!
So now, assuming none of the above is possible...referring now to the ati 5770 that you referred to...you mention it works with 10.6 well, and that windows 7 supports it ...2 questions on that
1) Windows 7 supports" meaning, out of the box windows 7 supports it? or will i have to install drivers still through some update, because again, if that's how i have to do it, then won't work, cuz can't start windows to see anything to install any drivers or run any thing at all...so it would have to just work with initial installation.
2)hardware wise for my Mac Pro 3,1...intel dual quad core xeon, blah blah....will this card work? it's a PCIe and should fit on my board no prob, etc?

Facing Black catridge problem within 2 months of purchase HP laserjet p1108 by printing 300 pages.

Hullo sir,
I'm Facing Black catridge problem within 2 months of purchase HP laserjet p1108 by printing 300 pages.The printer window shows you have to print pages < 50.what cani do?

Hi @thangaraj,
I see by your post that you have only printed 300 pages and it is now it is showing you have less the 50 pages left.
I would like to help you resolve this issue.
Is this the original toner that shipped with the printer?
You should get approximately 1500 pages according to the specifications for what ships in the box.
The page count is based on page yield. Depending on what you were printing.
Still I believe you should have gotten more then 350 pages, unless you were printing full page pictures in black and white.

Lumia 920 - Black update problems, slow app respon...

I have had a lumia for well over a year in the UK, I updated to the black update a week ago, and the phone became completely unresponsive, similar to theDej's problem here: http://discussions.nokia.com/t5/Nokia-Lumia/Phone-inoperative-after-lumia-black-update/m-p/2372351/h...
However, I contacted the carrier (EE) and they replaced the handset. I set up the replacement handset, which then prompted for the update, and I took the plunge and applied it again.
Now, although the handset mostly works, some apps have stopped functioning, and most importantly the WiFi settings and Bluetooth settings pages often become completely unresponsive, drop their connections, and dont show any available connections, so I cant reconnect to WiFi or bluetooth without restarting the phone. Also on some occasions, turning off the phone shows the "goodbye" screen, but either doesn't turn off and returns to the home screen or it magically restarts without me pressing the power button.
Has anyone come across any issues like this, is there anything I can do?

Please, try the Nokia Software Recovery Tool and report your results. We have a lot of Bluetooth/Wi-Fi issues reports since Lumia Black – no problem here. However, we have so many, sounds like several different issues.

My PSU is a 850watt EVGA SuperNova G2 so i know it's not that what causing the problem.
rest of my setup as follows
3770K @4.2Ghz
MSI Z77 Mpower
8GB corsair memory
ect ect.
Any idea's as to the cause of the problem?
edit here what it doing I've uploaded it to youtube.

First of all remove any oc. Then list specs more detailed: >>Posting Guide<<

I bought my Mac Air 13' in August. Black screen problems constantly happens. I asked some of my friends who also use Air. They share the same experience. Overall, it is a pretty good computer. But it bothers me when I do work and it suddenly goes black.

without more information, I assume you mean a blackout from sleep issue.
Go to system preferences > energy settings > raise the "turn display off" setting up to as needed, say 5 mins. or 10 mins.
AND ...
unchecked the "Put hard disks to sleep when possible" in both the battery and power adapter tabs.

Fifa 12 airplay via appletv, black screen problem

FIFA12 Appletv airplay black screen problem.
Hello, i wanted to play fifa 12 iOS with tv via airplay. But it dint work, i see game picture for half second then tv goes black screen. Audio still working and game i can go to play, but i cant see the game picture. This is very sad because every other game works with tv via airplay. The only game which would be really great with airplay doesnt work :( We tested it with two different tv and two different iPad 3's. And the tv is 40" the other one was much smaller and apple tv is the newest one with newest software.
Has someone else had this problem? is the apple tv problem or maybe fifa 12 have bug or something? i hope we can get this working, iv seen fifa 12 via airplay working very nice in few youtube videos so why it doesnt work for us.
also where would be best place to contact fifa12 makers for this problem.
Sorry for my bad english, it's not my national language.

Keep getting black slides after exporting a time-lapse in LightRoom

No matter what camera I use, I continue to get black slides in between frames of timelapses I make using Lightroom 5. I'm using a plug in that allows me to export the slideshow at 30fps. ANY HELP WOULD BE GREAT!

Me too. Would love to find an answer to this. As far as I can tell it's not to do with viewing it on a screen at the wrong fps, Lightroom is actually inserting black frames between the frames we put in...
