Pentax K5 and lens detection

Hello,
I have noticed since some LR revision that we have a problem in automatic lense detection(even in raw) with the pentax K-5 and some lens :
pentax SMC DA 18-55 3.5-5.6 AL WR : DNG ok, PEF ok
pentax SMC DA 50-200 4-5.6 ED WR : DNG ko, PEF ko
pentax SMC DFA 100 2.8 macro WR : DNG ko, PEF ko
for those ko lens if I chose pentax in manufacturer list it detects the correct lens model.
In can supply images if you need to correct those bugs.
Regards

My first question is why are you converting to DNG before importing into Aperture? It appears that Aperture should support the RAW files from that camera.
Second question is how familiar are you with the whole concept of RAW images? You realize that none of the camera settings (apart from shutter speed and aperture) affect the digital RAW file.
One of the strengths and reasons for shooting RAW is the ability to adjust white balance after the shoot. JPG images are extremely limited in their ability to have there white balance adjusted.
RAW conversion software is as much art as science, which is why no two RAW conversion programs will render an image in exactly the same way.
So I would first eliminate the DNG step and then see how that affects the workflow.
regards

My Mac is doing strange things: delaying between users, mouse flickering and bouncing, gets stuck with rainbow wheel flickering. I ran the appel hardware test and it detected an error: 4MOT/4/40000003:HDD-1233 Does anybody know what that means? HELP!

My imac is doing strange things:
-delaying between users: when closing session it goes to blue, then takes a while to appear users signin box, and then wont recognize mouse command to enter until a couple of minutes later... then everything seems alright until....
-it gets stuck between things, the rainbow wheel appears and its just delays there forever....
-and every now and then the mouse starts flickering and bouncing wildly onscreen.

WZZZ answered about where to get iStat. And do check the SMART status. If it is an overheating problem due to a fan or logic board problem, your hard drive is possibly cooking itself to death. If so it isn't a faulty hard drive even though the hard drive might fail. So assuming it's a temperature problem, even if you are able to repair things on the disk with software, that is working on symptoms, not causes. I could be wrong however.
RE: AppleCare: Your iMac came with one year of AppleCare (Apple's warranty program), but within the first year you can buy 2 more years. You have to extend by the one year anniversary of purchase of the computer. Your 10,1 is too old to still be in the first year, and since you asked what it was, I'm sure you don't have it. Bottom line meaning is that whatever this problem turns out to be, you'll have to pay for it. Unless there is something like this. It is for 2011 iMacs with certain Seagate drives. You can put in your serial number for fun, but it looks like yours is too old. Lastly, some people have had Apple help them anyway if it is just out of warranty, but many have not. Your machine is one of these. Type in 10,1 in the search box. Is there an Apple Store near you? Just b/c it's out of warranty doesn't mean you shouldn't have it looked at by Apple. But no one here can say at all what Apple will or will not do.
Hope you get it taken care of!

Directory Damage, what can be used for Disk Repair and Virus Detection?

Hi,
My eMac is acting up. Yesterday I started getting these messages that I needed to restart my computer (message was in a brown box window with an icon of a start up button in background).
I did the disk repair using Start up CD and it came back with "invalid key......." or something like that, and when I tried to repair it, it tried to repair the B-Tree's but then said it could not repair the problem.
I have Diskwarrior 3.03 Build 39, on a CD and on my FW Ext HD, which has a clone of my Mac HD.
Diskwarrior could not produce a graph of Mac HD because the directory was damaged. When I did a rebuild it hung on step 9 comparing directories, said there was 7 million + tests. ( I let it hang on step 9 for 15 hrs. to see if maybe it was just taking a long time due to corrupt directory). I finally clicked on Skip and got to the report page. I could do a preview, but the replace button is greyed out. When I was comparing the sizes of each folder, in both preview and original, I got a can not calculate error message on a few of them. The size of Mac HD in preview compared to the one in Original was different by 4 gbs. A week ago I repaired the Mac HD and did a Diskwarrior directory repair on all my HD's.
Before I do any reformatting of HD or other drastic measures, I was wondering what is safe to use for disk repair and virus detection. I know there is Norton System Works 3.0, Norton AntiVirus and TechTool, are these the only ones? Are these safe to use? Are there any other programs that can repair directory damage?
Thank you in advance,

The long-standing rule of thimb has been that if Disk Warrior can't repair a mungled disk directory, then you're looking at reformatting or replacing the hard drive. Since this is a week-old hard drive, I'd suspect the replacement hard drive is itself bad. It might save you grief in the long run to contact the vendor who sold you the drive and inquire about their warrenty. You might want to first run the file system check utility fsck as described in Using Disk Utility and fsck
Directory repair and antivirus protection are different critters. Norton AV is mostly safe (if you don't mind it's track record of false positives) and is used by the IT department at the lab where I work. Norton SystemWorks, AKA Disk Doctor Kervorkian, is most assuredly NOT safe. For every poster reporting something nice about it, you'll find at least 2 dozen cursing it. It has a known track record of detecting problems no other utility finds and of "repairing" drives such that nothing can then read or repair the drive short of low-level reformatting (and occasionally even that fails).
Tech Tool Pro 4 has a good reputation, as does Drive Genius. Tiger OS X 10.4.2 and later include a version of Disk Utility that can for the first time also make effective B-tree and keys out of order and overlapped extent repairs. Still, my personal gut feeling is that if Disk Warrior is choking on the hard drive, you're looking at reformatring while zeros the drive (zeroing should detect and map out bad physical secotrs).
You can also refer to Disk First Aid: What to do when it finds an error and to Handling "overlapped extent allocation" errors reported by Disk Utility or fsck

Odd Issue Editing in Photoshop with color and lens corrections

First off, I'm on LR 4.4 and PS CS6 (Camera Raw 7.4.0.137) using ProPhoto RGB as my LR colorspace and have my PS color settings as Working Space: ProPhoto RGB and my color management policies to preserve embedded profiles.
When I right click on a DNG in LR and choose "Edit in Photoshop", LR sends it to PS and PS does its "Reading in Camera Raw Format" and opens the image. However, the colors are off (very muted) and any lens corrections I've applied in LR are missing. My monitor (iMac on OSX 10.8) is calibrated with a Spyder. I've also noticed that if I choose to edit in another application, it renders the tiff fine and the color and lens corrections are correct in the tiff.
Anyone have any ideas what my issue is?
Thanks,
Matt
ETA: After some experimenting, it seems that the "Adobe Standard" profile is what gets sent to Photoshop. The rest (Camera Landscape, Portrait, etc.) are ignored. What's going on here?

Sounds like you need to reset your warning dialog. Preferences>General>Prompts [Reset all warning dialogs]
Then try it again and make certain of the three choices you are Editing a Copy with Lightroom Adjustments.

Metadata and lens profile don't match

Hi,
I have a Fuji X-e1 and the latest update of LR 4.4 running on 10.6.8, 16GB RAM, all OS software up to date.
The problem is my Fuji RAW files don't show the correct lens profile in the Develop module. The only choice available to choose is for Fuji X100 (which I've never owned or shot). The metadata in the Library module is correct for both the lens and camera, and also shows correctly in Bridge.
However, with the same software on a friend's Macbook Pro -- also 10.6.8, LR 4.4, etc. -- the lens profile correctly allows for the X-e1 and 18mm lens auto-correction.
I uninstalled LR on the desktop using an uninstaller called Zap It, downloaded 4.4, reinstalled and still the same 'error'.
Any ideas on 1) why the error and 2) how to correct it?
Thanks!

There are a lot of profiles for Raw-images but much less for JPG images.
Lr will display only those lens profiles that apply for the file format in question. So when you have a JPG image the profiles for Raw images will not be displayed in Lr, and vice versa.
If you don't have the correct lens profile in you list you have to download it.
For this you need the Adobe Lens Profile Downloader.
And for this program you need Adobe Air.
Download both programs from Adobe's website - they are free of charge.
Then install Adobe Air first, and when that is installed, install the Lens Profile Downloader.
Once it is installed just open it, it is self-explanatory and will display all available lens profiles once you have selected your camera and lens makes.

Missing Camera and Lens Metadata after iPhoto Import

I've noticed that the Photos for Mac app seems to have "lost" all of the Camera and Lens Metadata associated with each of my photos. Has this happened to anyone else?
No matter which photo I choose, the Info inspector window shows "No Camera Information" and "No Lens Information". I've confirmed that the Camera and Lens metadata is still present in the original iPhoto Library.
If I create a new iPhoto Library with just a dozen or so pictures and then choose that Library when launching Photos for Mac, by pressing the Option key while clicking the Icon, the photos are imported with the Metadata intact. Clearly something went wrong with the import of my much larger main iPhoto library. (The main library has over 100,000 photos in it.)
I'm wondering if there is some way to force Photos for Mac to re-index the Metadata. Any thoughts?
Thanks,
Michael

I have the same problem.. no lens metadata
will rebuild library with alt-cmd-start-Photos help?

Drag and Drop - detecting drop away from a component

Flex 4, AIR 2.0 app
I have a drag and drop detecting a Button drag away from a Group1 into Group2.
When the user drops into a Group2, the Button is added to it, which obviously removes it from Group1.
I would like it that if the user drags away from Group2 and drops it randomly on the screen, the Button will be added back into Group1.
Does anyone have any ideas as to how I might go about detecting the end of a drag when not over a component, so I can add the button back into Group1 again?
Hope that makes sense!!!

Thanks Ronnie,
I'll have a look at gthis as it looks a bit more efficient than the solution I have come up with.
The only thing I'm not sure about is at what point my Button gets put back into Group1. In my current movie, I have a function which handles the dragDrop event. But if I drop outside a component, I don't have an event from which I call the handleDrop(dragEvent) function.
I'll have a look.
In the meantime, what I'm doing is Making my drag item a custom component, passing a reference to it's default container (Group1) and its Default X and Y co-ordinates.
Then, I have a dragComplete handler which is called whenever the drag item is released - I then check the action property of the event and if it is "none" I know it has been dropped outside a recognised target and I can add it back into its default group and set its default x and y coordinates. This seems to work quite nicely at the moment.
so, my code in the Drag Button looks like this:
<?xml version="1.0" encoding="utf-8"?>

    // ask the DragManger to begin the drag

      event.target.x = _defaultX;

Lightroom, 5.5, Mac version: lens metadata incomplete and/or inconsistent. Photos taken with the same camera and lens display the lens metadata differently in LR 5.5, but are the same in the original files

LR is putting different descriptions of the same lens, used with the same camera, in the metadata of photos taken on the same occasion.
For example:
The following two images were taken with the same camera and lens.
They were imported at the same time into LR by copying.
The only difference in treatment is that the first was an untouched out-of camera jpeg, the second had been flipped using Preview on the Mac.
The one that was flipped has a full description of the lens, the one that was untouched has an abbreviated description.
When you show the file in the Finder and read the metadata using Preview, the correct full lens description appears.
Why is LR displaying the metadata differently for these two files?

Can you zip up a few of your GoPro images, upload them to dropbox.com and post a share link, here, so others can experiment with them, or do you mean this issue is global to all camera models?

Row and Column detection of a 2D boolean array

I use an array as showed by my example (LB8.2).
Press a 1 or 0 in the array changes it's value and it gives
back the Row and Column (that was changed).
I use this to program a 22 channel patterngenerator (GPIB).
It sends only the column (channel of patterngenerator) patterns, so that makes it faster.
Has someone an idea if this row and column detection can be made simpler (faster)?
Kind regards, Bernard

2 question about GPU and Lens correction ,cs5

Hi
i have 2 questions about Gpu and lens correction in Cs5
1)Filter->lens correction->search online
i get often and almost every connection time out at the first click on search online , at the second click i get no online profile
is it normal?
2) question is about Gpu
it run faster , but talking about ajustament layer
like saturation or vibrance for example
i found with the gpu on , a light slow refresh compared with gpu off
i have set cache levels 6 ,history 20
i guess are the defaul
well i add a saturation layer and move the saturation slide ,increase o decrease saturation
with Gpu Off , the changes are immedially , i mean i can see in real time the increase o decrease of saturation
with Gpu On it takes a few(very few) time more
again is normal ?
don't be angry , i'm going to buy cs5 and i'm unsecure ... the price make a big role
thanks

For what it's worth, I also see a timeout on the first [ Search Online ] click, after about half a minute delay. Second click turns up results immediately. This happens each time Lens Correction is started, even without restarting Photoshop, and in both 32 and 64 bit versions. Also note that I started with one profile listed by default (though from the wrong camera) for my 40D with 28-135 zoom.
I alsow noticed that I was seeing progress bar activity in the Lens Correction dialog while I was typing this (even though Lens Correction was NOT the active window) every time I hit the 'L' key. Strange.

New 27" iMac ejecting external hard drive and not detecting it consistently

I purchased my iMac from Best Buy two days ago and am wondering if I have a lemon. During the process of transferring files via an external hard drive I have noticed a number of issues. My old 2007 iMac had no problem reading the drive but my new iMac keeps ejecting the disk every couple of minutes. I will get a message in the corner of my computer stating that it was not ejected properly.
At one point, the new iMac would not read the drive at all. I plugged in my iPhone and it detected it at first but eventually ejected it and would not detect it again either, not even to charge it. I restarted the computer and it started detecting the iPhone and the external the drive, but now I am back to getting the same error message. I have tried to repair the disk using disk utility and it does not detect any problems. I also tried using every single usb port.
I would appreciate any suggestions and will be taking it back if it keeps having issues.

Fetch and peak detection all channels of PXI-5105 with 4M record... HELP!

Dear collegaues!
Please help me to improve performance my application, see attachment, and sorry for my English.
So, my task is to fetch and peak detection all (eight) channels of PXI-5105 with 4M record and sample rate 4M with loop 1 sec...
Inputs of all my channels are wiring to NaI detectors with 0,5...1 microsec of pulse width (really) and freq from 0 kHz to no more than 40 kHz.
Why I've selected 4M record and 4M sample rate namely? Answer is that I've tested PXI-5105 previously by generator 40 kHz and 0,5 microsec width pulse. It is working fine and peak detection indicate for me 40000 pulses/sec. If I set lower than 4M record and 4M sample rate it is no working. In my honest opinion 4M record and 4M sample rate are very min settings.
In the present time peak detection working only 6 channels... When I've connected to diagram more than 6 "peak detector.vi" - I see the error "...out of memory...".
Please advise me, what is to be done for that is all working fine.
Solved!

What you are running into is an out of memory error in LabVIEW. You have enough onboard memory to capture 4M samples per channel on the digitizer. The issue is with fetching and manipulating that data in your LabVIEW application. You will want to step back and take a look at how you are handling your data to understand why that is happening.
1) 4M samples/ch = 4M Samples x 2Bytes/sample/ch = 8M Bytes/ch
2) Expanding to 8 channels creates 64M Bytes of data in the raw binary format
3) You are scaling your data by fetching in a 1D WDT format. This stores each sample in a 32 bit double, expanding the memory to 256M Bytes (in addition to timing information)
4) By splitting up the array of waveforms and branching data it you can easily create copies of this data, and if your consumer loop is not completed with the last data, you may be trying to capture a whole new set, creating yet another copy.
So you can see that while you have 1.5GB of controller memory, when dealing with large arrays of data you can easily eat up that memory. There are several things you can try to make your application more efficient. You could work with an unscaled binary data format, you can wire the array of waveform directly to the peak detect vi (instead of creating 8 copies, you will have a single copy with arrays of output) or you could revisit the record size you have chosen (experimenting with your threshold and width settings might help you to get the results you want with smaller record lengths).

Missing camera and lens profiles in CS6 upgrade

I have just upgraded from CS5 to CS6 on OSX 10.7.5 and am running the latest software (ie CS6 13.05 and ACR 8.2.0.94). My old Canon 7D profiles are available in CS6 but I can't see any profiles for the latest cameras like the Canon 6D or Ricoh GR (among several others), which are meant to be supported. Is this a known bug and/or is there some fix?

I had lots of hassle installing CS6 the first time (ie installation error code U44M1P7 - tried lots of workarounds to no avail) so eventually deleted both the old CS5 and CS6 and did a fresh install of CS6. This worked fine and didn't appear to have any problems in then running all the latest software updates. However, the camera and lens profiles I was expecting to see in ACR and PS Lens Correction Filters just aren't there. I'm just using PS CS6.

How do I download camera and lens profiles?

I am new to CC. How do I download camera and lens profiles and install them in Photoshop and LR5?

Hope this answers your questions. If not check back.
Lens profile support | Lightroom 5, 4, 3 | Photoshop CS6, CS5 | Camera Raw 8, 7, 6
You did mention Photoshop CC, and Adobe Camera Raw 8.6 does have a lens correction tab
8.7 Release Candidate has updated ones as well. http://labs.adobe.com/downloads/cameraraw8-7-cc.html

Camera model and lens model

Just a bit confused about this in the metadata. Every time I reopen Ap 3. the camera and lens info on the metadata has gone. I then need to select all the photos I want the data for and in metadata click " update from master ". When I close that project and reopen the information has gone again and I need to repeat the procedure. Am I being stupid here by missing something obvious ??
douglas

Stola,
I am willing to share my lens profiles with others and I have sent this profile directly to Adobe and it is in the database, accessible from Photoshop CS5.
I will have to send you the lens profile as an attachment since a Lightroom user cannot access the lens profile database, according to what I have seen on this forum. You can send me a private message with your email address and I will send the file to that address, it is an 83 kilobyte file and is for RAW images, the NEFs, shot with the D700. I took 120 different images, not 27, to develop this profile, so it is a good one that I invested a lot of time in developing.
In order to send a private message to me with your email address to mail the lens profile file to, you would click on my name beside the post of the topic, and then when the menu comes up, on the right, choose "Actions", "Send private message", and then compose the note to send me your email address within the private message, unless you want to post your email address on the forum, which robots can obtain and then spam you with advertisements, etc..
