Standard Preview size/quality Lightroom 1.1. (how and what)

I'm working on a Macbook pro, with hi-res 17" screen 1920x1200. In most manuals, tutorials etc. it says that you can "set the standard preview size fitting for your screen".
I'm looking for some more background info on the standard preview, to decide which setting to use(if somebody has other criteria to keep in mind please do say so):
1) What is the difference in size of files for the different combination of options (pixel/quality). Does somebody have a list.
2) What is the actual difference in the quality options
3) In which modules is the preview size used (also in development and slide show?)
4) Are they also used to generate the thumbnails from? If so, does a higher standard preview size reduce the performance in library mode because it as to shrink bigger files for these thumbnails?
5) what happens if I would use the smaller, let's say 1440 preview and then decide to view the picture full-size, in library or slide show
6) What would be the size (in pixels) on the normal main window in lightroom on my 1920x1200 screen. if it is about 1440 (might take that one)
Last question of course: What standard preview size / quality should I use on my 1920x1200 screen??
Thanks in advance for all your thoughts!

As to standard preview size and quality, try 1440 and 1680 and Med and High quality and see what you like best. You will probably choose 1680 size for your screen running at 1920x1200. That will let you run LR full screen where the image size will be close to the full size of your monitor. You can try 1440 too but I doubt that you will see any performance improvement. I have tried both sizes on my 1600x1200 monitor and I see no difference in quality or speed.
Try both Med and High quality and see if you notice any difference in your preview quality or speed. High will make your preview folders bigger which might be a factor if you have limited hard drive space.
Don't think preview size has anything to do with thumbs. Standard previews are separate from 1:1 previews so you can always zoom in and LR will generate a full size preview.
In short feel free to experiment with various settings in LR. Good way to learn the program and you will know what works best on your particular computer.

Standard Preview Size/Preview Quality

This may be a silly question, but in Library mode, under Edit>Catalogue Settings>File Handling, you have options under Preview Cache for 'Standard Preview Size' (1024/1440/1680/2048/2880 pixels) and Preview Quality (High/Medium/Low)... but what do these settings actually do; I've tried changing them & not noticed and difference??

So are previews only created as required when you view a picture in full screen mode or does LR create a preview for all your files?
Every image you look at in Library module comes from the (library) previews, there are up to 8 possible jpegs:
* a tiny thumbnail in root-pixels.db
* up to 7 jpegs ranging from small to 1:1 in the "preview pyramid" (each smaller is half the dimensions of it's bigger sibling).
Try this with a 10 photo test catalog:
If you have a big monitor and set standard preview size to 1024, then (with Lr closed) delete all previews, then restart Lr and wait for all the "..." indicators to be extinguished (indicating standard previews have been built), then step from photo to photo in loupe view with all panels collapsed (loupe view "real-estate" maximized), you should see "loading" indicator, since it needs a bigger preview than you've got built. What it will do then is build 1:1 previews and all the smaller ones along with it, which is suboptimal from a performance point of view. If you try and zoom in to 1:1 after the "loading", there will be no additional loading, since 1:1 previews were already built.
Then, repeat the test with preview size at max - no loading indicators, right? (when stepping in loupe view after standard previews have finished being built, I mean). Except now if you try to zoom in there will be "loading", since 1:1 preview were not required to display the loupe view, they will need to be built for the zoomed (1:1) view.
The only difference between big enough and too big will be an ever-so-slightly greater lag when stepping in the loupe view and no 1:1 preview exists (when preview is too big I mean), since it's loading a bigger standard preview than is actually needed. Reminder: if preview is not big enough, there will be an ever-so-slightly bigger lag when stepping in loupe view too (e.g. vs. just big enough), since it's using the 1:1 preview instead of standard (which wasn't big enough). So, tester beware... (somewhat counter-intuitively, in some cases, it will be faster loading a preview when settings are, in general, too big, because it can get away with loading the next size down, which is an even better fit, e.g. if image is cropped just so - all of these little nuances make it especially tricky to test & evaluate, so consider doing initial tests using uniform-size uncropped images, to reduce the number of variables - it's confusing enough as it is ;-}).
Note: as previously mentioned, there is considerable complexity (and bugs) in the preview system, and I may not have described it perfectly, so it wouldn't surprise me if your results were not exactly like that, but I just went and retested on my system, and what happened is exactly as I described above (win7/64), as I read it anyway...
Regarding quality, you should see difference in some photos not others, but ONLY if it didn't resort to the 1:1 preview which may be higher quality than the standard and is independent of the standard quality setting. (I think somebody may have stated that you'd need to zoom in to see differences in standard preview quality settings, but that is wrong - the only way to see differences in standard preview quality settings is if you are in fact viewing standard previews, which you aren't when zoomed in to 1:1, and anyway it can be ellusive - see paragraphs above...).
PS - If you want to compare jpeg quality of standard previews, one way is to export them using PreviewExporter. Again, it's tricky, since you need to assure you aren't exporting a scaled down version of the 1:1 instead of a true standard preview. After exporting you can compare outside Lightroom, so you don't have the "preview of a preview" issue going... I use Beyond Compare by Scooter Software for doing objective comparison of like-sized jpegs, but you can compare subjectively using any ol' viewer, e.g. as built into OS.
Too much?
UPDATE:

No - they are created on an as-needed basis (thus the reason we hear many complaints about how stale or non-existent previews should be built in the background, to minimize "loading" in library module, e.g. after making dev changes to a large bunch), but note: standard previews may be considered "needed" when thumbnail is in view in grid or filmstrip (but not considered needed if thumbnail is off-screen, even if existing in filmstrip and/or grid).

Preview size & quality settings

Although I have been using LR for many months I am still confused as to what to set my import settings to when it comes to previews. Standard or 1:1? What quality settings? Can anyone enlighten me on best practices?

>... my import settings to when it comes to previews. Standard or 1:1?
Standard Size previews are of your choosing: 1024, 1440, 1680 and 2048. You set these in the catalog settings "File Handling" tab. Also, you can set the quality to Low, Medium or High. You could also think of the Standard Size as that which most closely matches you screen size.
1:1 Previews are previews that match the dimensions of the image and are generally much larger than the Standard Size previews. e.g. from a 10MP Nikon D200 the size is 3872*2592.
The implications of your choices are as follows:
- The larger the preview size that you choose, the slower the import
- Larger previews take more disc space in your .lrdata folder, specifically the thumbnail-cache file.
If you are going to import a large number of photos, that you may later cull prior to doing any develop work, then you could choose Standard Size previews, with a low (1440) pixel size, Medium Quality. Import should then be fast. After you have eliminated photos that you do not wish to keep, you could use the Library ->Previews -> Render 1:1 Preview, if you wish to generate full-size previews of the selected pictures. Again, this may take a significant amount of time, depending on how many photos you select.
When you go to Develop module, Lightroom will automatically generate a 1:1 preview of the selected photo. So if you are not concerned about a slight delay while Lighroom generates 1:1 preview in Develop module, you could stay with Standard Size previews for import.

Finder Cover Flow image preview size is small, cannot be adjusted and showing empty blank previews in Mavericks

When using Cover Flow the image preview in the main window (not the thumbnail list at the bottom) images appear but only use about 1/2 of the window space available. It is also showing black/blank preview images as I scroll through the files even though they are cached.
I enlarge the Finder to fill my 27 inch display, slide the size adjustment handle (three lines under the file name preview) all the way down as far as I can. The preview only enlarges to a certain point leaving the upper half of the window unused. I wish to enlarge the cover flow preview images to use this window space even if it affects the overlapping or number of cover flow images avaialble in the window. I am assuming this is becasue of the nature of cover flow showing the two previous and two following images to the left and right of the previewed image. As I scroll left and right occsionally one of the upcoming images will appear as and empty preview as well. It's all goofed up.
Hoping for any suggestions.
I have seen articles about using terminal to adjust "flow height" but never anything substainial that seemend like an informed solution.

I also would like to know if there is an answer to this. My landscape photos always display with a third of the cover flow window as blank empty space (matching your screenshot). This seems like such a waste. Is there any way to change the "padding" between the top of the finder bar and the cover flow preview?

Standard preview size? 1024 or2048

hi
i have a question
which setting is better 1024 - 1440 -1680 -2048
i have a 17 monitor
thanks have a nice day

For a 17inch display you don't really need much above 1024. Also note that these values relate to the Standard-Sized Previews. A full-sized (1:1) version is generated when you click and zoom on a thumbnail or preview.

Flash to DVD.... how and what format

Im trying to get my flash file converted over to a looping
video clip, on DVD that will play on a wide screen TV. Hope some
experts here can help with a few pointers.
1. I made it 1020x720.... should it actually be.... 1280x720?
2. I've downloaded several demos of SWF to DVD conversion
softwares, yet none seem to provide the graphics quality once
converted. What software is best?
3. What format is best to convert to for the best graphics?
.AVI, .MOV, .WMV, .MP3?
3. What's Bitrate do when converting? I assume higher is
better?
Hope someone here can at least provide me a few expert
pointers on how to best get my flash file to widescreen TV with the
best quality without spending hundreds on additional software. Oh,
and I am using Flash8 if that matters.
Thanks for any help!!!

Hello,
i have had also the problem to bring an Flashmovie to DVD in
widescreen format.
Here is my solution, maybe ist fits your problem, even late:
- Create Flashmovie with stagesize 1024x576
- create new symbol and insert all frames into this
- delete all frames and layer from the maintimeline
- modify stagesize to 720x576
- insert an instance of the newly created symbol in the main
timeline and add as much frames as you needed
- scale the instance in horizontal direction to stagesize,
its about 70.315%
- export swf-file
- convert swf-file to mpeg with an Aspect Ratio 16:9
Widescreen
(i convert with Adshareit SFW2Video, so i need to insert
frames as above said)
- add mpeg-file with DVD-Authoring tool to an DVD
so thats it.

How and what is generating response for an url ending with infoobject.cwr ?

See the attached file first.
I'm trying to find how the response is generated when i click on the notification tab. With firebug, i know that the request URL is :
businessobjects/enterprise115/admin/en/infoobject.cwr?&action=-10005&cmd=notification&id=245228
action     -10005
cmd     notification
id     245228
I'm trying to figure out where and how the response is generated. I can't find any mapping to a servlet corresponding to "infoobject.cwr".

Hi, ilplvm,
Calling directly into InfoView or InfoObjects is not supported or documented. If you'd like to access reports using URLs, then you can use "OpenDocument" [UR L Reporting|http://help.sap.com/businessobject/product_guides/boexir31/en/xi3-1_url_reporting_opendocument_en.pdf]
That doc, along with documentation on our SDK's is found in our [Developer Library|http://www.sdn.sap.com/irj/boc/sdklibrary].

Stress test Sharepoint 2013 portal. How and what do You use?

Hi!
I'm using example from here http://msdn.microsoft.com/en-us/library/jj710162.aspx
It creates record in SP task list. I can loop it to create several records. But how can I simulate
several users?
Or what in common sense do You use to stress test sharepoint? Any links or better there is a book?

>>You can use Visual Studio to create performance and stress testing projects.
Yes I know that I can use VS, it's in the link of my first post.
>>Check out my articles at:
Margriet, thank You very much! I see that You analyzed more than a hundred of tools and dived very deep into this question! Thank You for
the tool, it works for me!
1) But what You use to monitor server behavior, do You use Resource monitor? By example I can see some network and cpu activity during test, but how can I analyze this data..
or I'd use some video-capture tools(like 'camtasia studio'), record this system monitor and then analyze?
2) I understand correctly, that this tool covers "WFE test", mostly IIS, like pages generation; SQL database should be tested by other methods.

How can I use my IPad to monitor 2 web cams wirelessly in my children's rooms?

Search for webcam apps in the app store. Most work only with specific cameras. Check the manufacturer of yours and see if they offer an iOS app.

How and what to configure in the server configuration files of Tomcat Web ?

Hi,
I am using TCP/IP socket connection pooling in my project. For pooling I have written code, I want once the tomcat webserver starts there should be at least 10 instances of connections to be created in the pool. Could any one please tell me how do I do this in the server configuration files (server.xml or web.xml).
Thanks in Adv.

Take note: the mbaworld.com site has its Tomcat setup/environment poorly configured that the documentation which came along with Tomcat setup became indexed by Google. It has further completely nothing to do with Tomcat itself. Please refer Tomcat's own homepage at [http://tomcat.apache.org] for the documentation.

How and what do you sync with iTunes?

Can two Macbook Pro's share the same Itunes folder(all media in Ituens) on an external drive (like Time Capsule)? How and what issues may arise?

Hey, I have two macbook pros (250 gb). They are both running out of space. My first thought was to share an iphoto library off of Dropbox or our Time Capsule. But, I heard that if one file gets corrupted (interenet cuts out, for example) then the whole library gets corrupted. Well, we're full again and now I am wondering if I could move our Itunes folders to our Time Capsule, sync/sort them both so there won't be any duplicates and then use this as a shared itunes library. So first, is this possible? Both computers share the same itunes account.
Second, if I do, and I purchase a song, show, whatever, does it automatically be added to the itunes library on our Time Capsule and then it is available for both computers to access? Or do I need to "import" it on both?
Third, does the "file corruption" issue listed above pertain to itunes?
I saw a discussion about this but it was form 2008. I am sure things have changed a bit since then.
Thanks for the help!

Ora-011157 cannot identify but fixed but i do know how and whats the reason

There is a development going on in our clients place.
Strange thing happened and fixed today.Let me explain but i have fixed it
When we used sqlloader to load files from .csv i faced the above eror
or-011157 cannot identify ./temp01.dbf.
when i looked into the dba_data_files the temp01.dbf was not there.
so i decide to create a temp tablespace with temp01.dbf but got error
cannot add datafile as /temp01.dbf is aprt of datafiel.
I think our users dropped physically but i am not sure.
then i decided to offline the temp01.dbf
again i created the temp tablespace with name temp02.dbf
the the temp tablespace was created and sqlloader was working .
what was wrong
thanks

Hi,
tempfiles are not visible in dba_dat_files but in dba_temp_files

You'll need to connect it to the iTunes library you normally sync it with and restore it. If iTunes asks you for this passcode before it will let you proceed, connect the iPod to iTunes in recovery mode instead using the instructions in this Apple support document.
