Question about RAW+JPEG in LR 1.1

Hi,
I just want some information on how LR handles the JPG+RAW files.
1- When I look at the picture in LR, do I see the JPG or the RAW? (because the JPEG I get from my D50 is more punchy than the RAW, so I want to know which one I see)
2- When I want to modify the photo, do I work with the RAW by default (I suppose)?
3- Can I choose which one I'm looking at or working on?
4- Let's say I haven't got the time to work on the RAW and I need to send the pic. Can I decide to export the JPEG (with the punchy colors)(and resize it) or LR will automatically export the RAW?
5- Is there any advantage (in 1.1) to use old way (separate folder for RAW files, to have both in LR) than the new JPG+RAW capability?
Thanks a lot again,
Dany

Here's some info regarding this from Mete Atamel, engineer on the LiveCycle Data Services team:
When shared-backend=true, a single consistent view of data is guaranteed but this is not due to the shared-backend property itself but rather the fact that when shared-backend=true, there's a single DB used by multiple instances of LCDS.
Imagine the scenario where you have two LCDS nodes in a cluster with two data management destinations, one on node1, and one on node2, and they are clustered (via JGroups). You can have those destinations maintain their own DB, and when a change happens in one node¹s destination, the other node's destination gets a JGroups message and updates its own DB. This works but it's not ideal because at a given time, you¹re trying to maintain the same cluster state on two different DBs and there are times when the connected clients do not get consistent view of the data.
Instead, you can use a single DB and have the two destinations talk to the same DB, so you have a single consistent view of the data. When this is possible, you enable shared-backend property in LCDS destinations, that way when one destination updates the DB, and sends a JGroups message to the other destination, the other destination does not try to update the DB again, instead it simply passes the update message back to the connected clients without sending it to the adapter.

A Question about RAW and Previews

I have just recently starting shooting in RAW (mostly for the post production editing abilities - I am an avid amateur photographer bent on learning as much as I can). I set my camera to capture in RAW + L. I don't know why I feel like I want it to capture both the RAW and JPEG file, and thus leads me to my first question: Is it necessary to have the camera capture both the RAW and Large JPEG? I am assuming the answer to be no, as I am sure if after importing the RAW file into Aperture, you could always export a JPEG if you wanted one? So no need to fill up your internal memory (if using managed masters) with the extra JPEG? Is this thinking correct?
Next, if you do import RAW-only files and then want to export certain images, do you have a choice to export the original RAW image? It seems that it only allows you to export a JPEG Original Size. To answer my own question, perhaps you have to export the Master in order to export the full RAW file when exporting? If you want to export a JPEG, you have to export not the Master, but a version of the Master? Is this correct?
Lastly, I wanted to ask a question about Previews. I have my preferences set so that previews have the highest quality with no limits to size. What is the significance of setting it this way? I just assumed that if I wanted to share an image at the highest quality without exporting it, this was the way to go. Is there any validity to this? The reason I ask is that I don't want to have all of these high quality previews taking up internal disk space if I really don't need to. Is there a way to change the preview size once previews are created? Meaning, if you have it set to generate low quality previews, can you change it dynamically to high and vice versa?
I know this is a lot in one post. Thanks for tackling it.
Mac

You can change the quality of the Previews in the Preferences -> Previews tab.
You can regenerate Previews with the Delete and Update Previews under the Images menu.

Question about RAW to JPG file sizes

Hello all, I have a question/concern in reference to file size changes when converting from RAW to JPG formats in PSE6. I've recently purchased a CANON 50D, and have started shooting in RAW format (actually RAW2+JPG). I have the CAMERA RAW 5.2 plugin and my workflow process is something akin to this:
1. Separate all RAW and JPG images into their respective folders.
2. Open the RAW folder in BRIDGE, and then open up a CR2 file. CR2 file is approx 15MB at this point, as reported in Finder.
3. Perform various corrections in ACR52 to the file, then do as SAVE AS to a DNG file.
4. Next step is to OPEN IMAGE, bringing it up in PSE6.
5. Make any necessary corrections to the picture, and then do a SAVE AS to a new file name and folder, selecting JPG format.
6. Selection MAX QUALITY from subsequent dialogue box, and SAVE.
When the file is saved, its now down to a mere 2.1 or 2.2MB, and when viewing its properties (vs. the same file that came from camera in JPG format), its down from a 44x66" format, to somewhere around 4x6" and 240dpi.
I've been doing some reading on this over the weekend, but cant explain away the severe loss in file size, and whether this is right, or if I'm doing something wrong in the process.
Appreciate any advice or suggestions to help improve my work processes, and ultimately the final photos!

Regarding your file size questions, have a look at this thread and see if it answers some of your questions:
http://www.fredmiranda.com/forum/topic/741532/0
> When the file is saved, its now down to a mere 2.1 or 2.2MB, and when viewing its properties (vs. the same file that came from camera in JPG format), its down from a 44x66" format, to somewhere around 4x6" and 240dpi.
Dimensions and resolution are related and multiple combinations can be produced from the same number of pixels. For example, your 50D at maximum image size produces 4,752 by 3,168 pixels. This full-size image could be printed at:
- 19.8 x 13.2 inches at 240 PPI
- 47.52 x 31.68 inches at 100 PPI
- 7.92 x 5.28 inches at 600 PPI
As you can maybe see, talking about dimensions and resolution doesn't make much sense until you are ready to consider printing. Note also that I used "PPI" or Pixels Per Inch since this is the slightly more correct terminology. DPI or "Dots Per Inch" is usually a reference to how a printer lays down the ink drops onto the paper. Many printers actually put more "dots" on the paper than there are pixels. Many people and companies use DPI when they mean PPI.
Now in your case you are apparently starting with an SRAW2 raw file. SRAW2 files from the 50D have a reduced number of pixels and are 2,276 pixels wide by 1,584 pixels high. At 240 PPI this would allow you to print the image at 9.9 by 6.6 inches. If you are ending up with something smaller than that, it means you have either re-sampled the image (changed the image so the same image is displayed with fewer pixels) or you have cropped the image.
Hope that helps.

Question about showing jpeg metadata in lightroom

Hi,
I have briefly gone through the sdk material but there are some aspects that remained unclear to me. In more detail, I would like to show the RegionName tag from jpg-file in the LR metadata for searching etc. This tag includes the face recognition data from Picasa. I have already experimented with the exiftool and know how to add the names in RegionName to Subject or Keywords tag in both jpg-file and corresponding .xmp file for the raw-file. However, I would like to find an elegant solution by showing the tag in the LR directly. Before trying the make the LUA code, I would like to understand some basic principles behind the plugin programming namely:
1) How do I read the RegionName tag from the jpg-file and in which part of the plug-in? Is there a way to make LR read it every time the "Read Metadata from File" is used?
2) How do I "publish" it to appear in the Metadata panel on the right side of the LR (this is somewhat handled in the examples even though I do not understand the com.adobe.xxx reference i.e. which structure is it actually referencing to?)
Any comments and help is welcome on this or any advice where to find the information!
Mikko

Mikko,
LR provides access only to some metadata fields, not all. RegionName is not one of the fields LR knows about, so you won't be able to use the SDK's metadata methods to access or display it. Typically, plugins that want to access such metadata run the free Exiftool on the images and then parse the output of Exiftool.
The ExifMeta plugin exposes all metadata that's accessible by Exiftool as custom metadata fields in LR. I suggest you try out that plugin to see if it meets your needs. If it doesn't, you can examine its source code as an example of how to use Exiftool to access and display metadata. The plugin's author Rob Cole is a frequent contributor to this forum and quite willing to answer questions.

2 questions about RAW

I'm switching to shooting in RAW (Nikon D80) and read in The Missing Manual that the Photo Downloader in PSE7 may have trouble bringing them in from my card. Barbara suggests that there are other ways to do this and that they can be found on page 40, but I can find nothing there. So...
Does the Downloader work satisfactorily if I bring back a card with, say, 100 images on it? Or what is the best way to get them into Organizer?
After you've worked on your RAW images, what file format is best to save them as? Seems silly to save as JPEG unless they're going on the web. But what about TIFF? I see there's an option to save as Photoshop RAW.
Will appreciate any thoughts and opinions.

Hi, Jack. You can just use windows to import your photos to the computer, then use Get Photos>from Files and Folders. The problems with the downloader and raw have nothing to do with the number of images, only with the fact that people have more odd situations with raw than with other formats, particularly if you shoot raw + jpg. If you find that the downloader works for you, then it's fine to use it, but just be sure you're getting all the photos every time you download.
You can save your processed raw images in any format that the editor supports, so TIFF or PSD are both good choices. Photoshop Raw is an older Photoshop format, meaning raw PS data, not really an image format. Don't try to save anything as that.

Question about saving JPEGs in Photoshop for use in FCP

Ah, Mr Stupit here, I don't see anywhere else to ask, and since the pics will be used in FCP I"ll try here.
In photoshop I rotated the pics to get the figure upright for ease of handling in FCP, and now I'm asked to save the pic and I'm given the choice of Baseline Standard, Baseline Optimized and Progressive, with Baseline Optimized being the default. Usually I go with the default, but now I figured I'd be clever and ask the geniuses here what they think: Which should I go with?
Another question, am I losing some quality by re-saving this JPEG? I don't want to get into whether I should save as Tiffs, I find my FCP struggles with such large sizes and I'm happy with the JPEGs. Of course, maybe that's why I'm Mr Stupit.

Thanks for the reply!
The problem when I save them as tiffs, png, etc is they become really large and when I open them in Viewer or place them in a sequence I have to wait and wait while the little balls spins. I'm thinking that maybe I'll just use the original JPEGs and rotate them in the Canvas. As long as I don't re-save them there shouldn't be any difference in quality between using them in FCP as opposed to re-saving them as Tiffs, etc, and then using them in FCP, right?
Sorry, but someone on another forum said just using JPEGs in FCP will result in a loss of quality though why should an untouched original somehow lose quality by being placed in an FCP timeline, I don't get it nor did I get an explanation.
I guess I'm Johnny Stupit & Confused.

Beginner question about RAW/DNG files and Aperture + Adove

I used to use Microsoft Expression Media. When I would edit a .DNG file in Photoshop and update the sidecar or JPEG preview, EM would show the .DNG with the new adjusted preview in its catalog.
I noticed Aperture 3.0 doesn't read these adjustments from my .DNG files. Is there a way to get Aperture to properly read my .DNG files?
Conversely, when I make RAW edits in Aperture, can I view these on the .DNG master in Photoshop? How?

Adrian:
I have been using DxO Optics Pro in conjunction with Aperture. The easiest workflow that I have found is to run the images through DxO before bringing them into Aperture. I have DxO export the converted images as 8-bit TIFFs. (Sixteen-bit TIFFs are really big.) I, then, import the TIFFs into Aperture. There are two disadvantages to this approach: I do not get to bring the original RAW file into Aperture and using DxO on all images, even those that turn out to be rejects, takes a lot of time.
I have also played around with adding images to Aperture, exporting masters before doing any Aperture image manipulation, running the exported images through DxO, exporting the converted images as 8-bit TIFFs and reimporting the TIFFs into Aperture. This can be done without Catapult. I think the advantage of Catapult is that it will automatically stack your processed TIFFs with the original RAW files in Aperture. The advantage of this approach is that I can use Aperture to decide which images I want to process in DxO. Remember that DxO will not see any work that you have done on the image in Aperture; this is why I do my DxO work before doing any Aperture manipulations.

Question About Raw and Photo Size

I am beginning to work with raw in Iphoto. Nikon D300. When I edit the pictures I cannot tell what size they are as a jpeg. There must be a way but I have not discovered it. Any of the picture info I get refers to raw, not jpeg. When I email it to my self to see, it is reduced to a smaller size, like 385kb. I took the CF card to my PC and placing the cursor on it, I see the size, 10mb. Is there a way to see the size on Apple and can you determine the size and quality in Iphoto.

The question about RAW datatype in VBA with OO4O

Hi all.
I have developed a sort of VBA program with oo4o.
When I issued "select rawtohex(saddr),saddr from v$session where rownum < 2" and I displayed the result on excel spread sheet.
The result was below.
RAWTOHEX(SADDR) SADDR
C0000000E14ADDF0 �
I found I couldn't display a raw datatype result without using RAWTOHEX function.
But, I query the table using "*",such as " select * from v$session" sometime. So I have to display the raw datatype result without using oracle function.
I heard that the "RAW" datatype is a array of byte, so I used byte array.
The following is my first idea and the result is wrong.
The result is 'FF000000......', not 'C000000....'
Is there any good idea?
Dim oSession As Object
Dim oDatabase As Object
Dim oRs As Object
Dim cntCol, cntRow As Long
Dim rowNum, colNum As Long
Dim sraw() As Byte
Dim k As Integer
Dim hexaString As String
Set oSession = CreateObject("OracleInProcServer.XOraSession")
Set oDatabase = oSession.DbOpenDatabase(gTargetServer, gUserID & "/" & gPasswd, 0&)
Set oRs = oDatabase.DbCreateDynaset(gSqlString, 0&)
cntCol = oRs.Fields.Count
cntRow = oRs.RecordCount
ReDim resData(cntRow, cntCol) ' the variant type array to store result
'To store column title.
For colNum = 0 To cntCol - 1
resData(0, colNum) = oRs.Fields(colNum).Name
Next colNum
'To store data.
For rowNum = 1 To cntRow
For colNum = 0 To cntCol - 1
Select Case oRs.Fields(colNum).Type
Case 11
sraw = oRs.Fields(colNum).Value
For k = 0 To UBound(sraw)
hexaString = hexaString & Hex(sraw(k)) '<= here.***********
Next k
resData(rowNum, colNum) = hexaString
Case Else
resData(rowNum, colNum) = oRs.Fields(colNum).Value
End Select
Next colNum
oRs.MoveNext
Next rowNum
I hope I get helps.
Bill.

But, I query the table using "*",such as " select * from v$session" sometimeCan't you use
select rawtohex(saddr) hexaddr, t.* from v$session t
(if you really need '*' ) ?

Question about creating JPEG still from movie clip?

The aperture help says that a frame will be copied as part of a stack .. But I do not see this to be the case. When I make a frame from a movie, I don't see ANYTHING different in the browser window. Please help!

Yes, you can do that, but it's a little difficult to advise
you the best way with the information provided:
Can you clarify:
Do you want to play the main clip while the thumbs continue
to load... or do you want to preload the thumbs, then play the main
clip, then do the tweening when the main timeline reaches the end?
This way is easy enough.
If you want them to continue to load and then do the tweening
at the end of the main timeline (e..g with a stop() on the last
frame) then its also not complicated, but you need to cover the
situation where the loading of the thumbs may not yet have
completed by that time (perhaps the risk is low if the timeline is
long, but its a sensible thing to address regardless).
Also consider whether you want anything to be hidden (i.e.
_visible=false) at any point - e.g. before the thumbs have finished
loading.
As a starting point I suggest you would probably put the code
after
removeMovieClip("thumbLoading");
and before the last curly bracket (" } ") in a separate
function on the main timeline, e.g.
function tweenThumbs(){
//code here
(its actually not easy to be sure, because I can't visualize
what exactly it does)
what you would do next depends on the answers to the above
questions.

Newbie question about RAW in LR?

I have a Sony A550 and wanted to use image data converter for noise reduction on my RAW files and then use those modified Raw files in LR 2.5
It seems LR is doing it's own interpretation without taking previous modification into account? Isn't it possible? shall someone do all the required modification under one single software before exportation?
Can modifications be exported to another software in some way (enve from lightroom to image data converter)
Thanks for your Help!

You don't say what NR package you are using, and how.
Lr generally will not know that NR has been done on an imported raw image unless that previous NR was provided in an XMP-compatible manner. If the image was altered in-place (essentially replacing the image data) then Lr will apply NR based on the metadata it reads in the image data. Usually, this means a small amount of one kind of NR and none of another (except for higher ISO.) (This is from memory, so don't assume this is gospel.)
So, your best bet with this workflow is to create a develop preset with NR disabled and use that when importing these images.
Or, find out if your NR tool has a Lr plugin, and use that.

RAW+JPEG Import Question

I switched from Windows/LR to Mac/Aperture last year and have a question about importing RAW and JPEG files.
My camera (Olympus EM5) finally has RAW support and I have been shooting RAW+JPEG. I got a preset that I like to apply to the RAW files during the import. But I don't want the preset applied to the JPEG files. What I have been doing is importing the RAW and JPEG separately.
Is there a way to import them all together and have the preset only applied to the RAW files on import? Thanks.

What import settings have you tried? What configuration do you want the library to have (Both RAW + JPGs as separate masters or only one of them as master?).
If you want the RAW as master try importing as Both (RAW as master) to see if the preset is only applied to the RAW.
If you want both as masters, that is you're importing Both (Separate masters) then I don;t believe it will be possible to restrict the preset to just the RAWs on import. But instead of importing the images in two separate batches it might be easier to import both and to apply the preset after import using Metadata->Batch Change. It would be easy to filter just the RAW images to apply the preset to.

Hi I have a question about shooting in Raw with my Canon EOS 6d.
I'm in the process of learning photography and my goal was to start shooting in raw.
I have Photoshop CS5. When I tried to edit my images in raw I received an error message stating, "The photoshop camera raw plug-in did not recognize the format. If these files are from a camera, you may need to update your camera raw plug in."
In researching the issue I read that to edit in raw you need a camera model requirement of at least 7.3 which only works with CS6. My version of CS5 is 6.0.0.205. Being new to all this I see that my options are to upgrade to CS6 or convert by using DNG converter and paying a monthly fee. Two things I know nothing about and don't know which is would be more beneficial.
I'd appreciate any advise on which route to go and how upgrade and what it may cost. THANKS in advance!

In researching the issue I read that to edit in raw you need a camera model requirement of at least 7.3 which only works with CS6.
That is correct. Your camera was first supported by Camera Raw 7.3. Camera Raw 7.3 will not work with CS5. You need CS6 or CC.
Being new to all this I see that my options are to upgrade to CS6 or convert by using DNG converter and paying a monthly fee. Two things I know nothing about and don't know which is would be more beneficial.
I'd appreciate any advise on which route to go and how upgrade and what it may cost.
It all depends on your preferred workflow and your budget.
Using the DNG converter is free. There is no monthly fee. You use the converter to convert all Raw files from the EOS 6D to DNGs then edit the DNGs in CS5. That's an extra step every time - every photo. Some people don't like the extra step. Others don't mind.
Camera raw, DNG | Adobe Photoshop CC
Or you can upgrade to CS6 (non-Cloud) and pay the upgrade fee
Creative Suite 6
Or join the Cloud and pay the monthly fee
Or join the Photoshop Photography Program (US9.99/month) and get PS CC+LR

Some question about communicating the usb RAW device

I have some question about USB communication: I want to make my VI communicate

install the driver and run the test program, the driver program on DSP run
regularly. And then I want to program a VI which have the same function as the
test program, so I unload the driver on PC firstly, then install the DSP in
NI_VISA according to "Using NI-VISA 3_0 to Control Your USB Device - Tutorial -

This thread
contains already a related answer and explains what a sys driver is.
While you could theoretically use the Call Library Node to call all the
necessary Win32 API kernel functions to connect to a device driver,
this would be very cumbersome and not doable without a real good
understanding about C programming. Writing an interface DLL instead
won't need more C programming knowledge at all but will give you a
clean interface to that device driver which eventually could be used in
other programming environments as well.

RAW + JPEG Question

While playing with the import features I imported both RAW and JPEG for a project. I normally shoot only RAW but shot RAW+JPEG for this test. Is there a way to remove just the JPEG references from the Aperture Library? Or does the Aperture library only look at one image. So it’s either RAW or JPEG that the library is referencing?

If I understand your post correctly, there is an easier way.
When you import raw+jpeg into Ap, Ap Lib will contain both files but you only see the raw version by default. There is a simple option to to show both files in your Ap Lib. Sorry but I cannot recall where the option is (I don't do this so I've forgotten, but little search here should give you an answer quickly).
That said, the easiest is to view jpeg directly from your card or dump the card content into a temp folder before you import into Ap. I do this with raw file because I do not keep all the image on the card. In my case, I use ViewNX (Nikon) to quickly go through the images and delete unwanted images, then import the rest into Ap Lib (I use referenced master files so I also move the file into my permanent storage location before bringing into Ap environment).
