LR3 - Questions regarding virtual copies with different exposures and Merge to HDR Pro in Photoshop

Hello,
I'm currently testing LR3. I have a master copy and 4 virtual copies with different exposures selected in LR3. I tought to myself that I could simply use the "Edit / In Merge to HDR Pro in Photoshop" option and tune the resulting HDR image in Photoshop but it seems that Photoshop doesn't take in consideration the exposure changes I've made on the virtual copies in LR3. The 5 images are identifical in the HDR Pro tool.
Is there something I can do to about it ? Maybe there is a step I've forgot in my workflow or something ?
Maybe I could simply export the master and virtual copies to JPEGs and then import these in the Photoshop HDR Pro tool but I don't think I would get the same results right ?
Thank you for your help.

Depending on the image ISO and overall content, you can get some pleasing DR pickup using this routine over simply hitting the fill light slider up and the exposure slider down. I never really liked the PS approach since it seemed to require too much tweaking inside PS. I have experimented with LR/Enfuse and Photomatix plug-ins and have settled on Photomatix for my HDR exposures (both "real" with multiple images and "fake" with a single image as you have described). I think LR/Enfuse is donation ware so you might want to start there. In both cases, the resultant image still needs a little adjusting back in LR after it is automatically imported into the Library.

How to install Virtual Keyboard with Different language ?

HI,
How to install Virtual Keyboard with Different language (Arabic) in MacBook Pro ( Mac OS X v10.5.8 Leopard).
Thanks,

How to install Virtual Keyboard with Different language (Arabic) in MacBook Pro ( Mac OS X v10.5.8 Leopard).
What are you talking about exactly?
OS X comes with a virtual keyboard already. It is called Keyboard Viewer. You activate it by going to system prefs/international/input menu and checking its box (plus the box for Show Input Menu in Finder). At the same time you can check the boxes for the Arabic keyboard layouts.
You can then select the Arabic keyboard layouts and the Keyboard Viewer from the "flag" menu at the top-right of the Finder.
Let us know if you have further questions. If you are talking about some specific non-Apple app, could you provide the url?

Ability to process several raw files with the same content but with different exposure into the single picture

Can you add to the Lightroom an ability to process several raw files with the same content but with different exposure into the single picture?
Base raw files can be given with exposure bracketing during shooting, for example.
The goal - to get maximum details in darks and lights (if we use the "ligths recovery" or "fill lights" we lose the quality because raw file just have no all required information).
The similar (but not the same, only the idea) thing - is High Dynamic Range Photography in Adobe Photoshop
Thank you

The plugin LR/Enfuse does this already. And of course Photomatix have a plugin available for Lightroom. This essentially amounts to pixel editing, which is beyond the range of Lightroom's metadata editing.

One picture, two images with different exposures

I have a Rebel T2i EOS 550 camera.
When I take a picture and plug the memory card into the computer, two images of the picture show up. It appears they are with different exposures.
How do I stop the computer/card/camera from doing this, and only take one image?

If I had to guess, I'd say you are saving in RAW and jpg. Probably the difference in what you're seeing is that the camera is processing the JPG and the RAW file is just with the basic settings, waiting for further processing in DPP or some other software.
You can set the camera to save in just RAW or JPG.

Re: One picture, two images with different exposures

In DPP, RAW and JPEG will both show up. The one that says CR2 at the bottom is RAW.
Like previously said, check your camera setting.

I have some questions regarding setting up a software RAID 0 on a Mac Pro

I have some questions regarding setting up a software RAID 0 on a Mac pro (early 2009).
These questions might seem stupid to many of you, but, as my last, in fact my one and only, computer before the Mac Pro was a IICX/4/80 running System 7.5, I am a complete novice regarding this particular matter.
A few days ago I installed a WD3000HLFS VelociRaptor 300GB in bay 1, and moved the original 640GB HD to bay 2. I now have 2 bootable internal drives, and currently I am using the VR300 as my startup disk. Instead of cloning from the original drive, I have reinstalled the Mac OS, and all my applications & software onto the VR300. Everything is backed up onto a WD SE II 2TB external drive, using Time Machine. The original 640GB has an eDrive partition, which was created some time ago using TechTool Pro 5.
The system will be used primarily for photo editing, digital imaging, and to produce colour prints up to A2 size. Some of the image files, from scanned imports of film negatives & transparencies, will be 40MB or larger. Next year I hope to buy a high resolution full frame digital SLR, which will also generate large files.
Currently I am using Apple's bundled iPhoto, Aperture 2, Photoshop Elements 8, Silverfast Ai, ColorMunki Photo, EZcolor and other applications/software. I will also be using Photoshop CS5, when it becomes available, and I will probably change over to Lightroom 3, which is currently in Beta, because I have had problems with Aperture, which, until recent upgrades (HD, RAM & graphics card) to my system, would not even load images for print. All I had was a blank preview page, and a constant, frozen "loading" message - the symbol underneath remained static, instead of revolving!
It is now possible to print images from within Aperture 2, but I am not happy with the colour fidelity, whereas it is possible to produce excellent, natural colour prints using its "minnow" sibling, iPhoto!
My intention is to buy another 3 VR300s to form a 4 drive Raid 0 array for optimum performance, and to store the original 640GB drive as an emergency bootable back-up. I would have ordered the additional VR300s already, but for the fact that there appears to have been a run on them, and currently they are out of stock at all, but the more expensive, UK resellers.
I should be most grateful to receive advice regarding the following questions:
QUESTION 1:
I have had a look at the RAID setting up facility in Disk Utility and it states: "To create a RAID set, drag disks or partitions into the list below".
If I install another 3 VR300s, can I drag all 4 of them into the "list below" box, without any risk of losing everything I have already installed on the existing VR300?
Or would I have to reinstall the OS, applications and software again?
I mention this, because one of the applications, Personal accountz, has a label on its CD wallet stating that the Licence Key can only be used once, and I have already used it when I installed it on the existing VR300.
QUESTION 2:
I understand that the failure of just one drive will result in all the data in a Raid 0 array being lost.
Does this mean that I would not be able to boot up from the 4 drive array in that scenario?
Even so, it would be worth the risk to gain the optimum performance provide by Raid 0 over the other RAID setup options, and, in addition to the SE II, I will probably back up all my image files onto a portable drive as an additional precaution.
QUESTION 3:
Is it possible to create an eDrive partition, using TechTool Pro 5, on the VR300 in bay !?
Or would this not be of any use anyway, in the event of a single drive failure?
QUESTION 4:
Would there be a significant increase in performance using a 4 x VR300 drive RAID 0 array, compared to only 2 or 3 drives?
QUESTION 5:
If I used a 3 x VR300 RAID 0 array, and installed either a cloned VR300 or the original 640GB HD in bay 4, and I left the Startup Disk in System Preferences unlocked, would the system boot up automatically from the 4th. drive in the event of a single drive failure in the 3 drive RAID 0 array which had been selected for startup?
Apologies if these seem stupid questions, but I am trying to determine the best option without foregoing optimum performance.

Well said.
Steps to set up RAID
Setting up a RAID array in Mac OS X is part of the installation process. This procedure assumes that you have already installed Mac OS 10.1 and the hard drive subsystem (two hard drives and a PCI controller card, for example) that RAID will be implemented on. Follow these steps:
1. Open Disk Utility (/Applications/Utilities).
2. When the disks appear in the pane on the left, select the disks you wish to be in the array and drag them to the disk panel.
3. Choose Stripe or Mirror from the RAID Scheme pop-up menu.
4. Name the RAID set.
5. Choose a volume format. The size of the array will be automatically determined based on what you selected.
6. Click Create.
Recovering from a hard drive failure on a mirrored array
1. Open Disk Utility in (/Applications/Utilities).
2. Click the RAID tab. If an issue has occurred, a dialog box will appear that describes it.
3. If an issue with the disk is indicated, click Rebuild.
4. If Rebuild does not work, shut down the computer and replace the damaged hard disk.
5. Repeat steps 1 and 2.
6. Drag the icon of the new disk on top of that of the removed disk.
7. Click Rebuild.

Drive A + B = VOLUME ONE
Drive C + D = VOLUME TWO
What you put on those volumes is of course up to you and easy to do.
A system really only needs to be backed up "as needed" like before you add or update or install anything.
/Users can be backed up hourly, daily, weekly schedule
Media files as needed.
Things that hurt performance:
Page outs
Spotlight - disable this for boot drive and 'scratch'
SCRATCH: Temporary space; erased between projects and steps.

(normally I'd link to Wikipedia but I can't load right now)
Disk drives are the slowest component, so tackling that has always made sense. Easy way to make a difference. More RAM only if it will be of value and used. Same with more/faster processors, or graphic card.

I bougt a new Macbook pro in 02/26/2013, in 11/25/ 2013, my trackpad become bulging, they exchange the trackpad, but not the bulging battery. I went there yesterday, with different problem, and they said one screw came off from the truckpad again!

I bought a new Macbook pro in 02/26/2013 from Apple Canadian Ices -003. Than I could not use it, because my cursor uncontrollably was jumping around the screen, I was resumed my trackpad become bulging, Than on11/25/ 2013 they changed my trackpad for free, because was manufactoring defect, but not the bulging battery. They said that is do not needed. Since that my cursor is quiet often quivering, I think my Macbook has serious manufacturing defect. But they said no, during a year period I went to the genius bar at least 15 times, with this and similar problems. I went there yesterday, with different problems, and they said one of the screws came off from my truck pad, therefore they need to fix it and change it. I said: - What, how, what is the real problem? A screw does not comes off just like that? They will change my trackpad again, but not the battery. They said has to rebuild the operation system, I'm saving all of my data right now! I would like to exchange the battery too, or maybe get a new Macbook. My Macbook is 2010 China model. How long I would have this trackpad problem? What are you suggesting?

If it's a 2010 as you say towards the end of your post, it's out of warranty. The battery isn't covered in that case. Why don't you just buy a new battery if that's your concern? If it's a 2013 as you say up at the top, it shouldn't have a bulging battery. How do you know it does? If it really does, ask for the store manager and explain the problem.

1
Close all iWork applications
2
Uninstall Keynote; this must be done with an application remover tool to delete the installation properly. Appcleaner is known to work correctly for this purpose, it is free and can be downloaded from here: Appcleaner Download
3
empty the trash
4
shutdown the Mac and restart. After the start up chime, hold down the shift key until the apple logo appears
let the Mac complete the start up procedure completely, it will take longer than usual as the hard drive is being repaired
5
Reinstall Keynote by logging into the Mac App Store using download / install

I have 2 apple id's with different apps and data saved under each. It's very annoying so now I want to create a new id with my primary email address I use now. If I do that is there any way to transfer all my saved apps and app data like game saves etc so I don't lose all of that information and can easily switch to a singular apple id?

Apple does not transfer content bought with one Apple ID to another Apple ID. Apple will not merge two Apple IDs.
If most of your content was bought with the Yahoo! Apple ID but you now want the Gmail address for your Apple ID, the trick will be to change the address used for the Yahoo ID with the Gmail address. However, to do that you must first free the Gmail address from that other Apple ID. Use the instructions from Apple to substitute another address that is not used as an Apple ID for your Gmail address in the Apple ID with the Gmail address. Then, when the Gmail address is no longer used in an Apple ID, you can use the same instructions to substitute the Gmail address for the Yahoo address in the Apple ID with the Yahoo address.

I have an iPhone 5 and have just set up the iCloud for it. I also have an iPad with different content and I also want to connect it to iCloud. Will I lose everything that's on my iPad or iPhone or do they sync together without losing anything?

The problem is that all services are bundled with your Apple ID ([email protected]):
Your iCloud account (Mail, Contacts, Calendars, Reminders, Notes, Backups, etc.),
also iTunes & App Store purchases (Music, Movies, TV Shows, etc.),
and the iTunes Match services.
(I guess that all your devices - yours and your wife's are connected to one iTunes library, right?)
If you want that your wife gets her own iCloud account for Mail, Contacts, Calendars, etc. but gets also access to your media then you have two set up two things on her device:
iCloud (Settings > iCloud) with her account (e.g. [email protected])
and
iTunes & App Stores (Settings > iTunes & App Stores) with your account (e.g. [email protected]).
In this case she gets access to your library and could use the same iTunes Match account.

Setting a fixed and consistent exposure level with merge to HDR Pro?

I do panoramas with sets of bracketed HDR images. From LR I select my stack and then merge to HDR pro in CC. CC then produces a screen with a white point preview slider or the option to tone in ACR. Since I want to tone in LR I have tried to set the white point consistently for each HDR output in the panorama set, but I cannot get consistent exposure levels. I then try to adjust them all the same in LR, but sometimes differences result in undesirable effects in the panorama stitched output.
How can I get a 32bit HDR from PS CC back to LR and have each stack come back in with exactly the same exposure without me trying to guess with a slider?
I task all the images for the panorama with identical settings. Same brackets, fstop , shutter speed, ISO, etc. I should be able to get them all processed into 32bit HDRs and looking the same without manual adjustment guesses.
Thanks.

I'll tell you my workflow for panoramas such as this. Starting from bracketed stacks of images.
1. I select all images, go into Develop and turn on auto-sync. Turn on "Remove Chromatic Aberration". Do not turn on "Enable Profile Corrections". Set a custom white balance to make sure all images are WB'ed the same and optimize sharpening and noise reduction. Basically you want all images to be developed exactly the same and fairly conservative at that.
2. Export all images to 16-bit tiff in prophotoRGB or adobeRGB (depending on how colorful they are)
3. At this point one can add a logo to the nadir shot or do it at the end using the workflow I described above.
4. Load all images into hugin. Generate control points. Optimize positions - first just positions, then positions and view. Level the panorama in the GL preview and make sure the projection is set to equirectangular and the view to 360x180, then optimize view, barrel and positions and finally "everything without translation". During all these steps remove errant control points by going into the control point list and deleting the ones with the largest deviation, which are usually bad control points on clouds or other moving things. Also make sure the pano stays correctly leveled.
5. Mask the tripod out of the images that have it in them using the mask tools in hugin. Mask feet and stuff out of the nadir shot.
6. Do a photometric optimization with high dynamic range, fixed exposure.
7. Go to stitcher, set the optimum canvas size, uncheck "exposure corrected, low dynamic range", Check A. "exposure fused from any arrangement", B. "High dynamic range->tiff", or C. "blended layers of similar exposure, without exposure correction" depending on what you want to do.
8. Stitch
If you did A. You will get a tone mapped image that you can work up further in Lightroom or Photoshop. That image will be tone mapped respecting the wraparound on all sides so it won't have weird seams in a spherical projection. If you did B. you get a 32-bit tiff that will work great in Lightroom and as long as you don't use highlights, shadows, clarity and such will remain good. If you did C. you can load the multiple panorama layers you get into a HDR Pro in Photoshop, and load that into Lightroom.

I cannot import my AVCHD files by using log and transfer. I can see all the files, but when I add the file to import que it doesnt work, the status is a red and says that its no data. I have tried with different cards and different cardreaders, but it is still the same. Why?!

Please give us more specific information -
What make/model camcorder are you using?
Are you absolutely certain this is AVCHD video? Tell us more about the video settings you used in the camcorder (eg, frame size, frame rate, quality level)
Why are you attempting Log & Transfer from a card reader instead of from your camcorder? Have you tried doing Log & Transfer from your camcorder?
Are the SD cards straight from the camcorder, unaltered, or are you just using the cards as storage?
Are you using FCE 4.0 or FCE 4.0.1?
