Android OS Korean MP3 Tag fix

I enjoy listening Korean Song on the Smart phones but most of the times, when I transfer MP3s onto Android OS Smart Phones, the Korean in the Mp3 Tags are all broken….

I discovered that it is cause by the MP3 Tag Version and the easy fix is to re-write the MP3 Tags with the correct(?) version.

If you re-write the MP3 Tags with ID3v2.4, the problem goes away~

I find Mp3tag is good enough and easy to use for this fix.

AF Focus Test Charts

I have to say that I was never happy with my Nikkor 85mm F/1.4 AF-D lens outputs.  After using it on D800E and D3, I was sure that its AF is off – back-focusing….  So I looked for some good AF Focus Test Charts on the internet and found some.

I must say that I am rather disappointed with the results of my AF testing on all of my current Nikkor lenses.  Only one lens is spot on and the rest needs some AF Tuning on the both cameras.  For some reason, they all experiences back-focusing and none with front-focusing…

Camera Resolution Test

The new Nikon D800(E) produces 36MP shots out of the camera and I always wonder how they compare with medium format digital back(MFDB) outputs like Hasselblad H3DII-39.  In the camera world, size matters!!!  In the film world, film size matters!!!  In the digital world, the sensor size matters!!!  The question is about the 35mm format lenses.  Can they produce 36MP cable images?  I am not going to even try to answer this question.  Here are some of the charts that I use to compare/discover the resolution of the lenses and camera sensors.

Hasselblad H-series Battery Recalibration/Reset

 

The process to re-calibrate the full battery gauge:

1) Charge the battery for 8 hrs in the charger.

2) With NO battery, lens or viewfinder installed on the camera, press the orange on/off button for a few seconds to make sure the camera is fully discharged.

3) Press the flash and menu buttons at the same time on the camera grip, and hold them as you install the freshly charged battery.

You should then here a rapid series of beeps(three short beeps within a second or so on H3DII/H4D) indicating the PMU on the battery has been reset. If not, repeat steps 2 and 3.

With the battery installed, press the button just above the on/off button and hold it to see the battery status. It should read 100%

Notice that there is “DEMO” stripe on all of the Workflow on the left column – Display Profiling, Projector Profiling and Printer Profiling and also the question mark on all of the items under the Licensing section on the right side.

Now, go ahead and plug in the i1Display Calibrator to any available USB port then the “DEMO” stripe will be gone from Display Profiling and Projector Profiling and also both monitors and projector under the Licensing section are now with green check mark.

i1Profiler-Initial2

Let’s switch to “Advanced” mode : check on the “Advanced” radio button on “User Mode” on the right-hand column:

i1Profiler-Advanced

Under “Workflow” on the left-hand column, under “Display” section, click on “Profiling”

i1Profiling-Profiling

In the “Display Settings” on the right-hand side, change parameters as the flowing:
Default Display Settings: leave it as is, it probed what type of screen you have and selected the technology type automatically.  On my laptop, it knows that it is LP156WF1_TLF3 and selected CCFL for me, which is correct.

White Point: Native

Luminance: 100 cd/m2

Contrast Ratio: Native

Flare Correct: un-checked

Ambient Light Smart Control: un-checked

i1Profiling-options

Now, click on “Next” button.

i1Profiling-settings

Click on “Next” button again:

i1Profiling-PatchSet

Click on the “Next” Button on to the “Measurement” screen:

i1Profiling-Measurement

Click on the “Start Measurement” square button under the color pallets:

X-Rite’s Automatic Display Control(ADC) will try to adjust the luminance and contrast on your display.  Some of the monitors/laptops, this will work and it will automatically proceed onto the color measurements but if it cannot perform ADC, it will ask you to manually adjust the luminance and the following a few more steps are required.

Follow the instructions on the screen.

i1Profiling-measurements1

It will perform the Brightness Adjustment and shows the Luminance of your monitor, adjust your brightness so it will be as close as the Target White Luminance(100) then click on Next button.

i1Profiling-measurements2

It will start displaying different colors with different shades to measure the display performance.  This will take a few minutes.

After the color measurements are done, it will perform the ambient light measurement.  Just follow the instructions on the screen.

i1Profiling-MeasurementDone

Click on the Next button and go onto the “ICC Profile” screen:

i1Profiler-ICCProfile

Here, we are going to give a name to the ICC Profile that was just measured.  In my case, it named it as “LG Display_  LP156WF1_TLF3.icm” which does not make much of a sense.  Let’s name it with model of the monitor with the today’s date so we know when this ICC Profile was created, e.g. “EliteBook8560w-130105.icm”

Choose “None” on the “Profile Reminder”

i1Profiler-ICCProfile2

Now, click on the “Create and save profile” square button on the right.

i1Profiler-Done

Now click on the “Home” button.

That’s it!!!  You are now successfully calibrated your monitor and created adjusted ICC Profile.
