Followup question about wireless scanning (and many thanks to PaHu)

Hi,
Got my Canon MP980 communicating properly with my macs AND our linux machine now!
I'm having no luck using the bundled MP Navigator EX to scan documents and photos.. everything appears to be turned on and initialized correctly, the printer is on and idle on the home screen. but when I hit the scan button I see the error message:
cannot communicate with scanner. cable may be disconnected or device may be turned off. and an error code of 1.0.0
Is it possible the scanner (or this app) won't do it wirelessly? I can't use a cable without re-arranging a lot of furniture, lol.
Best regards,
Chris

Hello Chris. I believe the MP Navigator software should work across the network, however it may have to be configured to do so. (Personally, I don't use the application - I've never found it to be that reliable. I prefer to scan directly into Acrobat using the Create PDF > From Scanner).
I would think that in order to get Navigator working, you need to ensure that the network scanning utility is working and correctly configured. When you installed the IJ Network Tool, it should have also installed the Canon IJ Network Scan Utility. Often it will add an icon to your menubar that looks like an art-deco desk lamp. If it hasn't or you aren't sure which icon this is, you can open the application by navigating to Mac HD > Library > Printers > Canon > BJPrinter > Utilities and opening Canon IJ Network Scan Utility. This will display a pane that lets you set the MP980 as a network scanner. Once you have the MP980 you can then start scanning from an application to test.
You can use Preview, but you will need to register the scanner first via Image Capture, located in Applications. When you first open Image Capture, you may see a message stating that no image capture device is connected. To register the scanner, click on Devices > Browse Devices. This pane will show 'Canon MP980 series Network'. Click on the 'Use TWAIN UI'. Another pane will now appear asking where you want to scan the file to, what name to call it and the format to save it as. Enter/select your desired settings and click Scan. The ScanGear window should now appear letting you preview the image and select a variety of other settings. Select Preview, highlight the section of the image you want, and press Scan to finish the scan.
Once you get the above working, then you can try and get Navigator working, but as I have said, I don't think you need it unless you want to initiate the scan from the machine.

Question about Wireless Design and Controller

Hi Everyone,
Although I am not new to Cisco, I have somewhat limited experience with Wireless in general. I was hoping to get your help with the following:
We currently have a total of 8 1130AG, 4 on each floor. They were configured a few years ago, and now we are looking to update the design a bit. Each AP has its own SSID, and just provide internet access. Looking at the configuration, I noticed that they are not configured to use proper channels, just random channels (9, 10, 11, instead of 1, 6, 11, etc.). I noticed that when I roam between one AP to another, I lose about 4-8 pings before I re-establish connectivity again.
Here are my questions:
1. Do I need a controller in order to use just one SSID for the whole setup instead of the 8 seprate ones we currently have?
2. Will the controller helps in providing seamless transition when a client roams between AP's?
3. Is it normal to loose connectivity roaming around?
4. Can I reconfigure the current setup to use just one SSID and provide better transition between AP without the use of a controller?
5. Which controller would you recommend?
We don't have a need to anything fancy ,I am aware that I can enable multiple SSID, VLAN's, etc. Just trying to keep it as simple as possible, yet reliable.
Your input is appreciate.
Thanks

1. With 8 AP's only, a WLC would be nice-to-have but not necessary. You can configure WLSE and it will do some limited functions.
2. This depends on the signal strengths, wireless coverage and configuration. If you enable WLSE, for instance, and you have no wireless black spots, then roaming should be no issues.
3. See #2.
4. You can configure multiple SSID (up to 16 are broadcasted) but if one AP doesn't have the SSID you use for roaming, the association will drop when the client tries to join that particular AP. It's like mobile phone towers. If your carrier is not in the area, you sure won't be able to use your mobile phone in that area.
5. For 8 1130 APs, I'd recommend the smallest of the lot: 2106 with either 6, 12 or 25 AP licenses. I'd recommend you the 25 AP licenses. If your finances allow you something bigger, then consider either the 4402 (25 AP licenses) or the 5508.

Question about Wireless Controller and LAG.

I have a Wireless Controller 4400.
When I configure the controller with LAG, I have to connect the controller to a L3 switch?
If I connect the controller to a L2 switch the LAG works?
Some one can tell me something about this?
Thanks in advance,
Rui

Copper? so you are using rj-45 Gb SFPs on the controller. If that is the case, what is the speed of the switchports on the 2960?
I use the rj-45 Gb SFPs on our 4402s and they work fine connected to Gb rj-45 ports on the switches.
Also, check out the following:
http://www.cisco.com/en/US/docs/wireless/controller/4.2/configuration/guide/c42mint.html#wp1116136
"Using the CLI to Verify Link Aggregation Settings
To verify your LAG settings, enter this command:
show lag summary
Information similar to the following appears:
LAG Enabled
Configuring Neighbor Devices to Support LAG
The controller's neighbor devices must also be properly configured to support LAG.
â¢Each neighbor port to which the controller is connected should be configured as follows:

â¢The port channel on the neighbor switch should be configured as follows:

Question about wireless security and setup.

Ok, I have a pretty long house and my router is in the garage and I want wireless access in my bedroom. Here's the deal. Coming from the wall I have cable modem plugged into a WRT54g. That feeds 5 or 6 different WIRED PC's on that side of the house, but the other side isnt wired. So 1/2 way across I have a WRE54G setup as a range extender to reach the bedroom. I just bought a WUSB11 because the pc in the bedroom has no open PCI slots, and doesnt need the speed of G so a B connection should be fine. If I turn off all security everything is ok, everybody gets connected, including the neighb's. So I turned on WEP in the router WRT54G, it generates 6 keys I setup the WRE54G from my laptop sitting right next to it, and I enabled WEP in that as well, so I enabled WEP there and entered key #2 from the list supplied by the WRT54G, key#1 went into my laptop, which connects just fine. HOWEVER in the bedroom the WUSB11 sees the network just fine, but no matter WHAT key I enter into the WUSB11 it will NOT connect in anyway. anyone have ANY ideas? I would REALLY love to have this working and I would HATE to have top turn off my security, I really dont like o tust ny neighbors. thanks j

thanks wizzard, now I had a chat going with linksys tech support and they suggested that the WEP keys in all THREE devices be the same. now I may have left out of my original message the fact that key #1 that was generated by the router, is currently being used in an ACER laptop that has a NON linksys G device, and it connects just fine. so should EVERYTHING on the wireless be using the same key? and oobviously the same transmit id (1) thanks for your help j

Question about clear page and reset pagination

Hi,
I have a question about clear pages and the reset pagination in an URL. What is the reason why a clear page doesn't also trigger a reset pagination on the pages which are cleared?
I can't really imagine a business case where it makes sense to clear all data of page items on a page and don't reset the pagination of reports on that page which probably use a page item in there where clause...
The drawback of this behavior is that a developer always has to set the reset pagination checkbox when he clears the target page and the even bigger drawback is that if you specify other pages to clear, you can't reset pagination for them, because reset pagination only works for the target page.
Thanks for your input.

A question about item "type and release" of source system creation

Hello expert,
I have a question about item "type and release" of source system creation.
As we know,when we create a web servie source system,there will display a pop-up which includes three items as "logical system","source system"and "type and release".
About the item "type and release",when we push "F4" button,there will be three default selections as below:
"ORA 115     Oracle Applications 11i
TLF 205     Tealeaf 2.05B
XPD 020     SAP xPD".
Who can tell me when and how should I use the three selections.
And also I attempted to input the item by some optional letters except the default three selections and it seems that I can input it freely.
Thank you and Best Regards,
Maggie

Hello DMK,
Thank you very much for your answer.It is very helpful for me.
Can I ask you further about it?
I got that it is a semantic description item.
You said the default selections are set by our basis people.Would you like to tell me how should we creat a new value except the default ones for item "type and release"?Only by inputing the value in the item directly?But you see we canot see the new value item we created by ourself when we push "F4" button next time ,is that ok?Or do we have to ask basis people to define one new value item just like the default seletions before we use it.
Also if possible would you like to describe detail about "This becomes important when you are troubleshooting certain issues especially when RFC connection problems."
Thank you and Best Regards,
Maggie

Question About Color's and Gradients

Hi all,
I have a question about color swatches and gradients.
I am curious to know, if I have 2 color swatches that I make into a gradient color, is it posible to change the tint of each indivdual color in that gradient and have that applied to the gradient without having to adjust the gradients opacity.
The reason that I'm asking this is because in creating a project I found that the colors that I chose for to make my gradient from my swatches were to dark, and while I can adjust each one's tint to my liking (if the object they were applied to was going to be a solid color) but that doesn't seem to apply to the overall gradient.
I hope that makes sense, I know that this was something that was able to be accomplished in quark and was wondering if I can do something similar.

If you double click your gradient swatch (after adding it to the swatches)
Then click a colour stop in the gradient, and then change the drop down menu to CMYK (or rgb)
And you can alter the percentages there. It's not much use for spot colours but it's a start.
But making tint swatches would be a good start anyway.
At least then when you double click the gradient (in the swatches) to edit it you can choose from CMYK, RGB, LAB, or Swatches and adjust each colour stop to your liking.

The question about portlet customization and synchronization

I have a question about portlet customization and synchronization.
When I call
NameValuePersonalizationObject data = (NameValuePersonalizationObject) PortletRendererUtil.getEditData(portletRenderRequest);
portletRenderRequest.setPortletTitle(str);
portletRenderRequest.putString(aKey, aValue);
PortletRendererUtil.submitEditData(portletRenderRequest, data);
Should I make any synchronization myself (use "synchronized" blocks or something else) or this procedure is made thread-safe on the level of the Portal API?

HI Dimitry,
I dont think you have to synchronize the block. i guess the code is synchronized internally.

A few questions about the ka790gx and dka790gx

i have a few questions about the ka790gx and dka790gx , how much better is the dka790gx compaired to the ka790gx ? . how much difference does the ACC function make to overclocking etc , i plan on getting a phenom II 940BE or 720BE . i already have the ka790gx so would it be worth building another system using the dka790gx mobo , or should i keep what i already have and just change the cpu ?

It's largely irrelevant what other boards had VRM issues other than the KA790GX - the fact is it died at stock settings. Since there is little cost difference between the more robust DKA790GX (or Platinum if you really need 1394) why bother with the proven weakling? There are other examples around of the KA not having a robust power section. There's no way I would use even a 95W TDP CPU in the KA and absolutely not O/C.....!
As for the credentials of Custom PC, I have generally found their reviews accurate and balanced, and echo my own findings where applicable. If a little too infrequent.
The fact that the KA has such a huge VRM heatsink leads me to my other comments on the Forum, particularly regarding the "fudge" aspect:
"""Henry is spot on - the notion that adding a heatsink to the top of the D2PAK or whatever MOSFETS is effective is virtually worthless. The device's die thermal junction is the tab on the device back - which is always against the PCB pad. The majority of heat is therefore dissipated in to the board, and the fact that the epoxy plastic encapsulation gets hot is simply due to the inability of the heat to be conducted away from the device die via the tab. Not sure when Epoxy become an effective conductor of heat.... Good practice is to increase the size of the PCB pad (or "land" in American) such that the enlarged PCB copper area acts as an adequate heatsink. This is still not as effective as clamping a power device tab to an actual piece of ali or copper, but since the devices used are SMD devices, this is not possible. However, the surface area required to provide sufficient PCB copper area to act as a heatsink for several devices isn't available in the current motherboard layouts. Where industrial SBC designs differ in this respect is to place the VRM MOSFETs on the back of the PCB on very enlarged PCB pads - where real estate for components is not an issue.
Gigabyte's UD3 2oz copper mainboards sound like a good idea, on the face of it. However, without knowing how they have connected the device tabs to where and what remains a mystery. I suspect it is more hype than solution, although there will be some positive effect. From an electrical perspective, having lower resistance connecting whatever to whatever (probably just a 0V plane) is no bad thing.
The way the likes of ASUS sort of get round the problem is to increase the sheer number of MOSFET devices and effectively spread the heat dissipation over a larger physical area. This works to a degree, there is the same amount of heat being dissipated, but over several more square inches. The other advantage of this is that each leg of the VRM circuit passes less current and therefore localised heat is reduced. Remember that as well as absolute peak operating temperature causing reduced component life, thermal cycling stresses the mechanical aspects of components (die wire bonds for example) as well as the solder joints on the board. Keeping components at a relatively constant temperature, even if this is high (but within operating temperature limits), is a means of promoting longevity.
For myself, the first thing I do with a seperate VRM heatsink is take it off and use a quiet fan to blow air on to the VRM area of the PCB - this is where the heat is. This has the added benefit of actively cooling the inductors and capacitors too....
Cooling the epoxy component body is a fudge. If the epoxy (and thus any heatsink plonked on top of it) is running at 60C, the component die is way above that.....
It's better than nothing, but only just."""

Question about composite index and index skip scan

Hi,
I have a confusion.
I have read Burleson's post on composite index column ordering (http://www.dba-oracle.com/t_composite_index_multi_column_ordering.htm) where he writes that
"......for composite indexes the most restrictive column value(the column with the highest unique values) should be put first to trim down the result set..."
But 10g performance tuning book tells this about INDEX SKIP SCAN ::
"... Index Skip scanning lets a composite index be split logically into smaller subindexes. In skip
scanning, the initial column of the composite index is not specified in the query. In other words, it is skipped.
The number of logical subindexes is determined by the number of distinct values in the initial column.
Skip scanning is advantageous if there are few distinct values in the leading column of the composite index and many distinct values in the non-leading key of the index......."
So if we design Composite indexes acc. to what Burleson said then how can we take advantage of index skip scanning. These two staements oppose each other,don't they ?
Can anybody explain this ?

Question about Noise Margin and Line Attenuation a...

1.       For several years I have had a BT telephone line. From the utilities provided by http://www.kitz.co.uk/adsl I find that I am connected to the Exchange at Merton Park (BT Code: LSMEPK) Distance:-   Direct:   960 metres (appx)* By Road: 1.29 km. Exchange Status ADSL enabled: March 30, 2000 DSL Max enabled:   March 30, 2006 SDSL enabled : Enabled 21CN due : (PSTN) N/A 21CN WBC (Broadband)   Enabled 15.02.09
2.       I previously had broadband from UKOnline and used a Speedtouch 570 adsl modem. I was paying £9.99 for a speed of 1MBit/s – in practice 700K – which was fine for most purposes but BBC iplayer did struggle a bit. UkOnline has been taken over by SKY so I switched to BT Total Broadband Option 3 in mid December, and initially used the Speedtouch 570 as there were delivery delays on BT Home Hub 2.0 due to weather conditions. Speed was initially very good but did not measure it.
3.       After Xmas I set up the BT Home Hub and ran a speed test - the profile was 2.5MBit/s. I was disappointed to get less than 3Mbit/s which is needed for BBC iplayer HD.

4.       As part of the “slow speed wizard” I looked into getting the accelerator plate for my NTE5 split face master socket available for postage only (£1.20) but the web form advised me that if I proceeded with this order the broadband contract would automatically be extended by 12 months. I checked my BT internet account and was surprised to find an email (23rd Dec 2010) advising me that as an Option *1* customer I was in danger of exceeding my usage allowance – which surprised me as I am definitely Option 3. I wondered if I had had the speed throttled. Therefore phoned BT accounts who said the email was a mistake - I am Option 3, also said that accelerator plate was unlikely to make a difference.
5.       I contacted the BT call centre who talked me through various options. Plugging the hub direct into the master socket made no difference. They also ran a line test and said the line was fine.
6.       I therefore browsed the community care forum and find that disappointing speeds are not uncommon. One of the threads mentioned disconnecting the bell wire on the extensions. I follow this advice and removed line 3 on all extensions and then checked the ADSL status on the hub.

7.       This had a dramatic improvement on Upstream speed – and a big change to the noise margin Noise margin which had been (Down/Up) 15.7 dB / 31.9 dB and is now Noise margin (Down/Up) 31.8 dB / 14.4 dB. It did not improve the download speed.
8.       In the following days the BT hub has not been particularly stable with some intermittent loss of wireless connectivity every few hours. Examining the event log I was a bit disconcerted to see alterations to firewall settings had happened (which I hadn’t made) and resets which I am pretty certain I hadn’t made – and a userid login with a name like TR69. Perhaps these are occasioned by the BT speedtester? To be fair I had reset and powered off the hub a number of times in attempt to sort out this problems.
9.       I have switched to a Netgear DG83GT (V1.03.23) for the time being until I have what I can regard as a reasonably fast stabile connection. At the time of writing this has been stable for 20 hours DownStream Connection Speed 2268 kbps UpStream Connection Speed 888 kbps.As stated earlier I would like downstream to be faster.
The perceived wisdom on the forum seems to be that several days of complete stability are required if there is to be any improvement on speed.
10.   If a moderator or anyone with the relevant experience reads this I would be very grateful for answers to the follow questions:
A.      Is the change in the Noise Margin parameter a good thing or a bad thing?
B.      Are the line attenuation figures acceptable for a distance of under 1.5kilometres to the exchange?
C.      Should I be able in theory to get a faster speed i.e. downstream 3Mbit/s?
D.      From the forum it seems to take several days for speed adjustments to be effected or to take effect – is this a technical issue or a policy issue?
Many thanks.
Robert

These were not initiated by me - and since noise margins and sync speeds changed as a consequence can I assume that this is evidence of the adaptive process working?
Secondly, as you can see, the noise ratio has vastly improved as have the upstream and downstream sync speeds

BUT from the BT speedtester, as shown below I seem to be stuck in a banded IP profile of 1750/1091 which is very different from the downstream sync speeds of 11199 Kbps(DOWN-STREAM)
Can BT staff take action to alter this? If they can how do I contact them?

3 questions about FCP 7 and Blu-Ray

Hi Folks,
After reading the other posts on Blu-Ray and FCP 7 I still have just 3 questions:
1. I would like to get an internal burner. I see that at MacMall they have one that is specific for my MacPro model (2008) and there's one that they sell for the 2009 version. So it seems that I have to select a specific drive for my Mac Pro model correct?
http://www.macmall.com/p/MCE-DVD-Drives/product~dpno~7785361~pdp.fedabdd
Does anyone recommend a specific brand/type?
1. If I add the chapters mark on my project and export to a Quick Time file, will the chapters be present and accessible when I burn the Blu-Ray disk?
2. Looks like the best option is to buy Toast but, just to make sure I understood the issue with the share to Blu-Ray: If I just have one simple project with a movie with about 10 chapters, is it worth trying to use the option to share to Blu-Ray or is it not recommended for any type of project?
OK, I know I said 3 questions Just one more?
Back in the days, I remember compatibility issues with some types of DVD media and DVD players (DVD-R, DVD+R, brand, etc). Is there such a thing with Blu-Ray media and the current players?
Again, many thanks for your time and patience!
Best regards,
Ismenio

I use OWC (macsales.com) for purchasing blu ray burners. good company.
Not certain on markers.
I create blu ray disc with Compressor in FCS3 without many issues but not using Share.
I don't advise using Share.
Set your markers on a short clip.
Export self contained with the markers, and then use Compressor directly

Some basic questions about foriegn key , and relationships.

Hi
Thank you for reading my post
I read some documents about foreugn key and tables relation ships.
but i still can not understnad some stuff.
1-when we have a foreign key , we have two tables that we want to relate them together
in a way that one of ? table columns forced to be a value from ?? table column.
what is name of those two tables , i saw , child-parent , ..... which confuse me.
can some one please tell me correct name of those two tables ?
2-some times we need some kind of master details relation like :
one-to-many : i this case MANY table will have a column to point a record in ONE table , can this relation be a foreign key relation ?
3-we can achieve many-to-many relation only by using a helper table to host both tables primary keys in a record to relate them together.
can you point me to some resources that help me to find answers to this questions ?
or explain them to me ?
thank you for your time.

These are critical database basics that you need to understand. I would seriously recommend getting some study in, because proper relational database design relies on the basic principle of data and relationships and a process called normalization.
In reality, you only really need one gigantic table to host data. It would include everything you would want to know about something - let's take a sales order for example. You would have to record the customer's name, address, etc. along with every item they ordered, etc. You would have a HUGE table full of data that appeared over and over and over again. This is bad design for two basic reasons: it is difficult to query, and it is very easy to have minor mistakes like capitalization or alternate spellings that prevent things from matching up properly. For example, let's say Bob orders 40 widgets and 40 digits. In our hypothetical table, we could put it in as Bob - 40 widgets and Robert - 40 digits. See how confusing this can get even in a simple example? And let's say you wanted to correct all of Robert's orders to say Bob and you found out there were 40 orders from "Robert" How would you know which ones to change?
The process of normalization helps to reduce the chance for these types of errors in addition to creating a good basis for indexes. You normalize the data by creating sets of parent/child tables with a "key" value to match them. In our hypothetical situation, you could create a table for orders and a table for customers. In the customers table you give all the detail for the customer in one place, and you assign each customer a unique number or ID. In the orders table we add the customer ID (NOT the name) and we ensure that we are getting the customer we want, in addition to saving a lot of space and eliminating redundancy. In our example, the customers table is the "parent" table and the orders table is the "child" table. The child table references the unique entries in the parent table via that id. That reference is referred to as a foreign key. The foreign key in the child table points back to the original and complete record in the parent table and eliminates the redundancy of keeping all that extra data for every order. Foreign keys in child tables always refer to a primary/unique key in the parent field.
That help?

Question about setting cookies and custom authentication

I have a question about setting cookies.
I have two different 'projects' in HTMLDB - we will call them App1 and App2.
I also have two different connection configurations setup in the DADs.conf file. - we will call them Connect1 and Connect2.
App1 is setup to use database authentication (no user is specified in the DAD) and uses Connect1. Once the user successfully logs in, we set a username cookie (this is a persistent connection).
We created a custom authenticatoin scheme for App2 - this scheme checks for the username cookie (set by App1). We would like for App2 to use Connect2 (HTMLDB_PUBLIC_USER is the default user specified and it uses connection pooling).
Is it possible to set a cookie from App1, Connect1 for App2, Connect2 - then redirect to App2 and pick up that cookie?
Here is an example of what we are trying to accomplish:
A user loggs into App1, we set a cookie, and the user is redirected to App2. If the cookie exists, we allow them access to the home page in App2, if no cookie, we redirect back to a 'Login Failed' page in App1. We don't want App2 to use the same database connection as App1 though, we need App2 to use connection pooling.
Is this possible? OR...Is there a better way to accomplish what we want to do?
This is an enhancement to an existing app. Our requirements are to use Database Authentication (setup where pass expires after 60 days or so, cannot reuse last 3 passwords, etc.) - which is already setup and being used by other applications in our organization. All of our users have accounts in the database. We don't want users to have a new username/pass - and we don't want to manage a separate group for HTMLDB apps.
The existing application uses HTMLDB's built in authentication - which uses database username/pass, and it uses connection pooling, but we cannot handle the pass expire stuff in it, unless there's something we're not seeing or understanding - at least that's how our DBA explained it to us.
Any help with this will be appreciated so much. I can send you the code we have if needed.
Thanks!

Same problem here. I have so many problems with this remote app. Is there an iTunes API? I would like to write my own remote app that actually works.

Question about "Native ISO" and Color Grading in PP

I have a question about "Native ISO" in the real world and how it relates to color grading. I was shooting 35mm film before all these digital cameras became flat-out amazing practically overnight. Then the goal was always to shoot with the lowest ISO possible to achieve the least amount of grain (unless you were making an artistic decision to get that look). If I was shooting outside plus had a nice lighting package I'd shoot 5201/50 ASA (Daylight) and 5212/100 ASA (Tungsten) 99 times out of 100.
I've recently been shooting a lot with the Blackmagic 4K and have read that its "Native ISO" is 400. Because of my film background this seems counter-intuitive. Yesterday I was shooting for a client and had the camera at an f16 with a 200 ISO. Because of what I'd read, I was tempted stop down to an f22 and change my ISO to 400... but the "little film voice in my head" just wouldn't let me do it. It kept telling me "Higher ISO means more noise... stay at 200 and you will get a cleaner image".
So how does it work with "Native ISO"? Should I really shoot at a 400 ISO every chance I get in order to capture the best image for how the camera is calibrated? Will it really give me more latitude when color grading? Or would I still get a cleaner image staying at ISO 200? I've Googled around quite, but haven't found any articles that answer specifically this question. Would love to hear from someone who knows a bit more on the subject or has a link that could point me in the right direction.
Thanks much.

Hey, shooter ... yea, interesting discussion and always nice to learn. Great pic, too!
jamesp2 ...
Great answer. I've followed quite a bit of the discussion about the BM cams as well, one does feel a need to check out the possibilities for that next beastie one will need to acquire. But ... which one?
I've always been a bit of a hard-case about testing testing testing. For instance, what happens with dome down or use of a flat diffuser vs. dome in the up position in metering? Back in the film days, we had our own lab and did our own printing as well as the um ... difficult images ... from other studios. I needed to know how to get exactly the same diffuse highlight no matter whether it was a "standard" light 3:1 studio shot, or a near-profile with no fill that needs dark shadows. I tested & burned through boxes of medium-format polaroid & 120 film and a lot of color paper. Finding? To get the same print time no matter the contrast or lighting style, needed to be metered either with the flat disc (Minolta) or dome-down (Sekonic) and held at the highlight-location pointed at the main light source. I could meter and nail the exposure every time. Ahh no, insist so many ... one must have the dome on/up and pointed at the camera! Right. Do that, change the contrast, and see what happens to your diffuse forehead highlight on a densitometer ... and see how your printing exposure times change. Oh, and you've just moved your center-of-exposure up or down on the film's H&D curve, which will also change the way the shadows & highlights print. In truth, though it was subtle, we had realistically no matter latitude for a best-case image with pro neg film as one had with chromes. You could probably get away with being "off" easier, but it still wasn't dead-on.
So wading into video ... oi vey, you may have noticed the things claimed here there & everywhere ... this setting is God's Gift to Humanity but no, it's total crap ... this sensor is totally flawed but someone else is certain it's the finest piece out there. Yes, opinions will be all over ... but ... in film, it was the densitometer. In video, it's the scopes. Truth. And getting to that can be a right pain. I've seen quite a few contradictory comments about using the BM cams in film mode and also at ISO 200. Yours above gives the most ... comforting? ... explanation (for me) because of your reference to your scopes & the waveform patterns. Thank you.
Love to learn ...
Neil
