Question on Recovery in ACR.

My camera is set to Uni-WB and I ETTR. For the vast majority of images, the ACR histogram shows highlights set to the very right side (as expected) with Exposure set at 0. (Of course this is after I've set WB). Occasionally I have an image that shows that highlights are clipped in all 3 channels as indicated by white showing in the triangle (probably due to my getting too close to the right when exposing). I understand (per a Bruce Fraser post) that when all channels are clipped nothing can be done to recover the highlights. (And my attempts to recover with either Exposure or Recovery sliders visually bear this out). What is bothering me is that when I move Recovery to the right, the white triangle (and the clipping warning when opt is held) both indicate that there is not longer any clipping. It seems to me that these indicators should continue to stay at white (and red) rather than indicate that clipping is not longer present. Comments?

Interesting. Maybe it could have something to do with the profile you're using? I'm testing with the Camera Standard profile.
I would like to see your file (as, I'm sure, would the Adobe guys). YouSendIt.com will host large files - send it to yourself then post the link here.
I actually did some more testing, and while I can't get the clipping indicator to go away with just the Recovery slider, I can make it go off with huge negative Exposure settings on a test image of mine that has only marginal overexposure. This is that image:

I can't explain why, unless perhaps math error resulting in a small value change may be playing up, that this should occur.

Follow up question on recovery data on USB flash drive

HP instructions say the 32 GB flash drive should NOT be branded as Windows 8 compatible. I bought a Sandisk 32 GB yesterday for $20 on sale, but it says on the back it is compatible.
Other more/or less expensive flash drives did not address whether compatible with Windows 8.
I have Windows 8.1
Thanks in advance for your help...
This question was solved.
View Solution.

Hi,
If the flash drive is listed as 'Windows 8 compatible' it cannot be used - the reason is because the HP Recovery Media creation software looks for an external device and flash drives marked Win 8 compatible show as internal drives.
In the example below, the 32 Gb usb flash drive 'Dave G' shows as an internal drive which cannot be used, while the usb flash drive 'Removable Disk H' would work.

Few questions about recovery on P100-400

Good evening all,
I have a few questions about recovering my laptop...
So, I was thinking if the only way to clean my entire disk is to use the Recovery DVD?
I ask this because I think that the computer becomes too "heavy" with all the applications it came with. So I was wondering if I can format the Hard Drive instead of recover it.
If I format the drive do I loose warranty? Is there any future problem related to genuine software?
It's possible to install Windows XP Pro (and not the actual windows xp media center) with the original Operative system's product key?
Thank you.
Best Regards.

Hello
I will try to give you few answers and I hope it will help you.

I do not understand what you mean with I can format the Hard Drive instead of recover it but you can do follow: install OS using delivered recovery media and after doing this remove all applications you do not need. After doing this maybe your notebook will not be heavy anymore.
> If I format the drive do I loose warranty?
NO.
> Is there any future problem related to genuine software?
I do not know what you mean exactly
> It's possible to install Windows XP Pro (and not the actual windows xp media center) with the original Operative system's product key?
No. Something like this is not possible. Product key belongs to delivered and preinstalled OS.

Filevault encryption: no security questions, no recovery code; how to revert?

Running the latest Yosemite (10.10.2) on an iMac (upgraded from Mavericks) ...
I decided I wanted to encrypt the boot drive on our iMac, so I clicked to turn on Filevault. Here's what happened:
I was NOT offered a recovery key. (As this point, I didn't know when the key is normally offered.)
I DID get a window that asked if I wanted Apple to save my key, and I clicked on the radio button to do so. Then I clicked on CONTINUE.
I did NOT get any security questions to answer, just a RESTART button. I thought, maybe the security questions come after the restart.
I clicked on RESTART and the iMac restarted and encrypted the drive (17 hours).
Concerned that I didn't have a recovery key, I read up on the forums. Sounded like if I simply used my user password, I could turn off Filevault to decrypt the drive, and I'd be back to where I started. I did so, and watched as it decrypted the drive (6 hours). Filevault indicates that is is "now off."
I thought I'd try again, so I clicked to turn on Filevault. This time, I did NOT get a recovery key (same as before) and I did NOT get the window asking if I wanted Apple to save my key — only an immediate RESTART button. I canceled.
I restarted the iMac, noting that the startup graphics were different — the iMac now starts immediately with an all-white screen, something that one forum participant said is evidence that your boot drive IS encrypted regardless of what Filevault says.
This concerned me because it now seemed like the drive might be encrypted and I had no recovery key and hadn't been asked any security questions.
I thought if I turned on Filevault I could generate a fresh recovery key that would supplant anything Apple was storing for me — and give me a chance to answer security questions.
I turned on Filevault and was, for the third time, NOT offered a recovery key but this time I DID get the window that asked if I wanted Apple to save my key. Apparently the restart at least added this screen. I cancelled.
So while Filevault says it is off, the immediate white start-up screen suggests the drive may be encrypted. Regardless, Filevault is not offering a recovery key or security questions.
I have sketchy ideas about how to rectify things:
I could start up from an external backup (unencrypted) of the boot drive, erase the boot drive, and clone the backup to the boot drive. Will that create a bootable (non-encrypted) startup drive? I don't think so ...
I could start up from the external backup (unencrypted) of the boot drive, erase the boot drive, then do a clean install of Yosemite on the boot drive. Would that clear any existing encryption? I don't know ...
Or I read about using Terminal to un-encrypt a drive?
Any advice would be much appreciated.
Thanks,
Bradley

Basic questions about recovery/repair preparation

When I got my machine, over two years ago, I made repair disks on DVD's per Toshiba's instructions. Now, with my nightly backups, I have it make a system disk image on a NAS device.
If I were to have a large failure and need to restore my system, is there anything I can do now that would prevent me from having to go back to my inital system install of two+ years ago and start reinstalling everything?
I guess what I'm wondering is if would making another set of more recent repair disks be useful at all in giving me a "jump start" on recovery and how my scheduled system disk image fits into the picture. I've heard some folks say system disk images from a NAS device can't be used but they were not particularly credible sources so I don't know.
Probably pretty basic questions, but having recently had a scare with my machine, I want to be sure I'm as prepared as I can be.
Thanks.

If you cannot boot from an optical disc or flash drive to a program that restores from that NAS image, Sally, then it's useless. What system/procedures are you using? Read the manual.
The original recovery discs in my view are not very helpful. I would use them only to establish whether hardware is at fault when debugging a problem. Daily backups are the best source of recovery. We keep ours for ten days and test the recovery procedure from time to time.
Most of us who make backup disk images create them on an external drive connect via USB. Windows 7 already has such a backup program. One can boot from a repair disc to restore that image.
As you realize, this is important Let's sort it out.

Question about Recovery Media Creator

Hello everyone, first of all, I don't know if this question should be in this catergory, but I thought this would be the best to post in.
My question is about the Recovery Media Creator procces. I was about to create the recovery DVD and I noticed there are several Recovery Media options (Recovery Media 1 to Recovery Media 3).
My question is, what are the differences between them? Does it matter if I only check one of them so I would need less DVD's or a smaller USB?
Thanks in advance.
PS. excuse my grammar or bad explanation if there is any mistake.

Using Toshiba recovery media creator recovery image saved on HDD will be copied on DVDs or USB media and it will be created as bootable media.
How many discs must be used depends on recovery image. For some notebooks 2 discs are needed and for some of them you need 3 discs.
The tool gives you also info which medias you can use and suggest you, for instance which USB device you need. For my U940 is 16 GB USB listed as suggested due to 9,2 GB recovery image.

Question on recovery

Hello all,
I think the following recovery should be possible but I'm not sure. Appreciate if you could shed some light.
Scenario
1) SCOTT user accidentally drops a table in SCOTT tablespace when the SCN was 100.
2) FLASHBACK is not enabled for the database. No way to Flashback the database.
3) RECYCLEBIN is set to OFF. No way to "Flashback table <tabname> to before drop".
2) Other users are still using the database and the SCN has progressed to 150.
Resolution to recover the tablespace to a point in time before the drop
1) alter tablespace SCOTT offline;
2) Restore datafiles belonging to SCOTT tablespace from the recent backup.
3) Restore all required arch logs.
4) recover tablespace SCOTT util scn=99
5) alter tablespace SCOTT online;
Is incomplete recovery possible at tablespace level within the live database? If yes, how can Oracle maintain SCOTT datafile at SCN 99 and all others at SCN 150?
To resolve the above situation, I normally create an auxillary database by just restoring and recovering system,sysaux,undo and scott datafiles from the most recent backup and perform an incomplete PIT recovery of the auxillary database to a point in time before the actual drop. I would then export and import the table from the auxillary database to the live database.
Restoring and recovering an auxillary database is a time consuming process so I was wondering if I could just restore and recover the affected tablespace in the live database itself.
Thanks for your time.

Hi Aman,
Thanks for your reply and time given to my doubt. Actually my doubt has raised due to above posted blog entry; in which the writer has not mentioned anything about another db. He simply has written:
"Assuming we have the latest backup, just executing the following statement would do everything needed to get the entire *tablespace* to a point-in-time in the past. Believe me, you don't have to do anything other than just this statement!"
So, here my doubt is how he is able to perform RMAN TSPITR without other db, with he help of recover tablespace ... auxiliary destination ...
I mean, even Hemant sir has said for Incomplete recovery; we need other db... So it caused me doubt please.
Sorry sir, if i am missing/asking something irrlavent to the OP's question.

Questions about recovery discs and partitioning Satellite A200-QH0

I bought a Satellite A200-QH0 model in Australia and due to lack of forums in our country I'd like to ask some questions here if that's ok.
The notebook contains 3 partitions - a 1.6GB "EISA Configuration" partition, the large OS partition, and the recovery partition. So I've made the recovery DVD??s using the Recovery Disc Creator tool as we aren't supplied with an actual disc. But I would like to know what these discs will do? My questions:
1. Will they truly return the hard drive back to _exactly_ how it was including the partition layout and pre-installed software?
2. Will the recovery DVDs work even if the drive has been repartioned? I would like to split the system partition to give space for data files etc. But will this extra partition stop the recovery procedure working properly?
Please understand that I'm not interested in reformatting the entire drive. I just want to split the OS partition. But in case I have to replace the drive in the future or something I'd like to know how close to "original" these discs will get me, no matter what I do to the drive?
Thanks,
Dave

Hi
Im not 100% sure how the recovery works on the Toshiba Australian notebooks but I presume the Recovery CD contains the Toshiba image with the Windows OS, drivers, tools and utilities.
I think if you would use the Recovery CD then the whole HDD will be formatted and all partitions will be erased.
I think the recovery partition will be not created using the recovery CD because the recovery CD was already created so the recovery partition is not necessary anymore

Canon MKIII Highlight tone recovery V ACR recovery

I can see the point of using the 1D MKIII's HTR feature with JPEGS for high contrast range subjects to hold important highlight detail.
What is the consensus re in-camera HTR for RAW, versus no in-camera HTR and using highlight recovery in AR V4 on RAW files? (less chance of shadow noise with ACR as highlight specific adjustment)
Are Canon merely reducing the exposure at the highlight end and increasing overall exposure from shadows up the scale hence their advisory notice that HTR technology may increase shadow noise?

>Personally, I would prefer to have the histogram show the true status of the exposure and not some shifted value
>What is "true status"? The in-camera histogram is based on the camera settings, which have no impact on the raw data. I would prefer raw histogram shown in-camera, at least as an option, but I don't think many customers share this preference.
This issue has been covered many times. Since the histogram is derived from the JPEG preview with most cameras, you should set the contrast to low. Contrast affects the quarter tones much more than the extremes of the histogram. If you want to see the channels without white balance, at least with Nikon cameras, you can upload a special white balance to the camera where the red and blue multiplers are set to unity (UniWB). Also you can upload a TRC to the camera to undo the gamma encoding, but I've never tried this.
If you do a bit of experimenting, you can correlate the camera histogram with the raw file and have a pretty good idea of what is going on with the raw file, and you can gain quite a bit of control over the histogram. Some cameras indicate clipping in the histogram when there is none in the raw file, and this can be corrected with the proper TRC.
IMHO, a raw linear histogram is not a good idea, since the data would be scrunched up on the left. A log base 2 histogram would correspond to f/stops and that would be my preference and also corresponds with human luminance perception, which is log.
>The exposure with HTP On is the same as with HTP Off, but the ISO will be halved with HTP On (that's the reason for HTP working only from ISO 200 up). The loss in the raw data is the least significant bit. As the 1DMkIII creates 14-bit raw data, this loss is practically meaningless (assuming that the extra bits or at least the first of them is not random).
If you halve the exposure, shot noise will be increased by a factor of 1.4 across the tonal range. Usually dynamic range is limited by the noise floor, rather than by quantization. The 14 bit ADC wouldn't address the increased shot noise, but it might reduce the read noise.

Question about the New ACR Corrections for Tonal Range

I find the new set of controls for tonal range in CS7 to be excellent! However, I am curious about what controls what. Black and Shadows work as I would expect but Highlight and Whites do not, at least in terms of traditional photography.
Highlights and Shadows are grouped together as I would expect, Black and White also. But if we are to continue with that progression, White should control the clipping point and Highlights the values a 2 stops or so above middle gray. I would expect Highlights to be similar to Brightness in CS5 except better behaved. It's reversed. Highlights =Recovery in CS5
It's confusing so I am suggesting that White control clipping and Highlight the upper values.

Thank you Patti for your response.
I think we are coming to this from different perspectives. Being so close to development of the current upgrade, I appreciate your insights as to how these controls work. I, on the other hand, am coming from long experience as a photographer and printer, exceeding 50 years at this point. So I have some legacy points of view, which is why I posted.
I spent this evening looking more closely. Here is a summary.
I messed with an excellent example for looking at this question, and I found something interesting. You can fix an image which already has clipping far easier with Highlights, but you cannot force an image with white values well below clipping into clipping using Highlights. The reverse is true with White. So, to fix a white clip, use Highlights, to force a white clip, use White.
Blacks and Shadows are different. You can both force and fix a Black clip with Black, but Shadows, while possible, has much less range. So Shadows are kind of vernier on Blacks. This is different than Whites.
I was basing my OP on only fixing clipping points, that is, bringing an image out of clipping, but not forcing into clipping.
So, indeed, what you and Jeff point out is closer to correct than my initial assertions. Yours are based on a broader range controls than possible in analog days. In naming these controls, one winds up with a foot in both the digital side and the old analog side, which gave rise to the names and the meanings.
So thanks to both you and Jeff for taking this up. It forced me into looking more closely at my conclusions, and while they weren't wrong outright, they were inadequate to the present state of the technology. Sometimes, experience can actually get in the way!
