Some Sample of night shoot panorama, taken with nikon D50 , Nikkor 35mm/f2 AFD lens with Iscorama 54.
Iscorama 54 Anamorph
Iscorama 54 adalah anamorphot lensa yang paling sering saya gunakan, untuk melakukan pemotretan panorama malam.
Perbedaan yang paling mendasar adalah bahwa iscorama mempunyai single focus, jadi anda cukup melakukan focus di iscorama saja, tidak perlu di lensa kamera(setting di lensa kamera di set ke infinity.
Hal ini tentu saja memudahkan pengambilan gambar dibandingkan dengan multifokus system seperti pada Anamorph lensa lainnya seperti Kowa B&H dimana anda harus memfokus di lensa dan di anamorph adapter untuk pengambilan gambar.
Atau memakai diopter di depan lensa anamorph, untuk bisa single fokus ( Rangfinder / Rapido) yang berarti ukuran lensa dan assesori anda bertambah panjang dan semangkin sulit untuk mengambil gambar dengan mudah tanpa “rig”!
Kamera dan lensa yang saya gunakan:
- Nikon D50 dengan lensa 35mm /f2 AFD
- Nikon D850 dengan lensa 50mm /f1.8 AIs
Iscorama 54 mempunyai bayonet depan sebesar 95mm untuk filter, dan bayonet belakang sebesar 77mm, saya kebetulan mendapat beberapa original adapter dari 77mm ke 55mm, jadi cukup di adaptasikan dengan filter adapter 55-52mm lens optik untuk mennyatukan lensa ini dengan lensa kamera.
Dengan Iscorama 54 ruang pandang lensa anda menjadi lebih lebar dengan faktor 1,5 X
Contohnya : untuk lensa 50mm menjadi seperti lensa (50mm : 1,5=) 33,33 mm.
Untuk mendapatkan Format sebenarnya anda mendapat perbandingan sisi gambar tidak lagi 2:3 untuk FF format tetapi 4:9
Dengan kamera modern anda, dapat juga mengambil gambar video dengan format (4:9) seperti di film film bioskop.
Lensa dengan focal terpendek yang dapat anda pakai adalah 50mm untuk FF dengan Iscorama 54, dan lensa lain seperti 85mm , 135mm, 200mm sepanjang filter depan lensa tidak lebih besar dari 52mm / karena lensa belakang Iscorama 54 adalah 54 mm.
Beberapa contoh gambar dengan Lensa 50mm / f1.8 AIs dan nikon D850:
Beberapa gambar contoh dalam format panorama:
Untuk setting dan contoh hasil foto di DX format silahkan lihat di sini.Untuk setting dan contoh hasil foto di FX format silahkan lihat di sini.
Opsi yang menarik adalah pembuatan video Anamorph dengan panorama format seperti film di bioskop. Dengan D850 misalnya anda dapat menggunakan Software Handbrake untuk dekompriminasi format ke format panorama kembali.
Ini Setting yang saya pakai untuk mengkomprimasi balik film atau video kebentuk panorama.

Upgrade Raspbian Stretch to Buster
Check your current OS version:
uname -a
cat /etc/debian_version
Prepare
Get up to date.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
Verify nothing is wrong. Verify no errors are reported after each command. Fix as required (you’re on your own here!).
dpkg -C
apt-mark showhold
Optionally upgrade the firmware.
sudo rpi-update
Prepare apt-get
Update the sources to apt-get. This replaces “stretch” with “buster” in the repository locations giving apt-get access to the new version’s binaries.
sudo sed -i 's/stretch/buster/g’ /etc/apt/sources.list
sudo sed -i 's/stretch/buster/g’ /etc/apt/sources.list.d/raspi.list
Verify this caught them all. Run the following, expecting no output. If the command returns anything having previously run the sed commands above, it means more files may need tweaking. Run the sed command for each.
grep -lnr stretch /etc/apt
Speed up subsequent steps by removing the list change package.
sudo apt-get remove apt-listchanges
Do the Upgrade
sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y
cleanup old outdate packages.
sudo apt-get autoremove -y && sudo apt-get autoclean
Verify with:
cat /etc/os-release.
Update Firmware
You have come this far, might as well get the latest firmware:
sudo rpi-update
Have fun with your new updated Pi! 😉
Installing Ride on Pi Zero
Installing Ride v1.7.4 on Raspberry Pi Zero with Raspbian is a Challenge, especially during preperation and installation of wxPython for pi Zero
Base setup from pi Zero:
- Rasbian buster lite
- python 3.7x
Do SW update before installing :
sudo apt-get update
sudo apt-get upgrade
sudo apt get dist-upgrade
Do Install pip3 for my pi zero:
sudo apt-get install python3-pip
Prepare installation before installing wxPython on pi Zero:
sudo apt-get install dpkg-dev build-essential swig python-dev libwebkit-dev libjpeg-dev libtiff-dev checkinstall freeglut3 freeglut3-dev libgtk2.0-dev libsdl1.2-dev libgstreamer-plugins-base0.10-dev libgstreamer0.10-dev libgconf2-dev libglapi-mesa libosmesa6 libglu1-mesa-dev libglu1-mesa mesa-common-dev
sudo apt-get install build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev
sudo apt-get install python3.7-dev
sudo apt-get install python-wxgtk2.8 python-wxtools wx2.8-i18n libwxgtk2.8-dev libgtk2.0-dev
sudo apt-get install gtk+-3.0 gtk+3.0-dev
sudo pip3 install pathlib2
Now install wxPython, it can take long (+/- 24 Hours) by pi Zero!
sudo pip3 install wxPython
If it’t passed you can install Ride !
sudo pip3 install --upgrade robotframework-ride
You can start the Ride now as remote sessions:
Ride.py &

Raspberry Pi & Robotframework
Why using Robotframework on Raspberry pi?
As Raspberry pi user , sometimes I have problems after doing OS update with some application I currently workout on pi, mean do “sudo apt-get update” , “sudo apt-get upgrade” & do “Reboot” everythings goes Wrong 🙁 !.
I have been using Robotframework since 2006, and would like to show you how simple to run a Regresion Test with Robotframework Framework on SBC like Rasberry Pi and Co’s. Robotframe work need only python ecosystem, which are out of the box delivered by Raspbian OS. And also it needs minimal resource of space in SD card.
As a sample I will start with installation of Robotframework , please check before if you have python pip installer installed on your Rasbian before starting with the installation!
Start Installation of Robotframework on Pi
sudo apt-get install python3-pip
sudo pip3 install robotframework
Check Robotframework runner:
robot --version
You can used nano or Test IDE Ride for writing Tests .
Installing Robotframework-RIDE test IDE:
sudo pip3 install robotframework-ride
Start RIDE on Mac with ssh conection to pi:
ride.py &
now you can start writing your Test, please refer to Robotframework manual for more Information.
Let check the SD card used for Robotframework Installation, just 1% from 16 GB SD card!
Wish you happy Testing and Try Out!
Testing Soap interface with Robotframework Library
For efficient testing sometime you need to created automaticaly request xml feeding soap interface. If you are familiar with robot framework, it’s great. Robotframework has already 2 external Library, which handle SOAP interfaces communication.( Süds Library or Zeep Library ) .
There are a lot of opinion in Internet about these two libraries, discussing pro and contra using one of these lib. for testing SOAP.
Important things to do, you have to find out which library can handle “your WSDL“ better!
For my task, Suds library does.
How to find it out?
Just run your SOAP Library keyword pointing out your target WSDL .
Used “Create Soap Client” keyword for testing the binding if you get all the entities and objects on your WSDL, If the answed “OK” than you can used your Library for SOAP,
… Ports (1): …. Methods (10): addToIndex(xs:string guid, ) getProductMetadaten(xs:string guid, ) getProductMetadatenGuidList(xs:string query, ) getProductMetadatenList() … Types (62): ns3:AbstractCurveType ns3:AbstractGMLType ns3:AbstractGeometricAggregateType ns3:AbstractGeometricPrimitiveType … |
If not you have to find out other library for interfacing with SOAP.
As sample I got these error using Zeep for parsing my WSDL:
self.item_type = self.item_type.resolve()
AttributeError: ‘lxml.etree.QName’ object has no attribute ‘resolve’
These error are related to these following open issue on Zeep:
- https://github.com/mvantellingen/python-zeep/issues/803
- https://github.com/mvantellingen/python-zeep/issues/513
Sample of created XML request from RF with Suds Library:
this is how I wrote it in Robotframework Test Suite:
map WSDL local | |
Run Keyword and Continue On Failure | setProductMetadaten |
this is how I wrote it in Robotframework Test Case:
show object setProductMetadaten | |
setProductMetadaten |
calling internal keyword:
${object}= | Create WSDL Object | n2:ProductMetadata | ||
Set Wsdl Object Attribut | ${object.commonMetadata} | identifier | ${dummy_text} | |
Set Wsdl Object Attribut | ${object.commonMetadata} | title | ${dummy_text} | |
Set Wsdl Object Attribut | ${object.commonMetadata.description} | summary | ${dummy_text} | |
Set Wsdl Object Attribut | ${object.commonMetadata.description} | comments | ${dummy_text} | |
Set Wsdl Object Attribut | ${object.commonMetadata.product} | type | ${dummy_text} | |
Set Wsdl Object Attribut | ${object.commonMetadata.product} | subtype | ${dummy_text} | |
Set Wsdl Object Attribut | ${object.commonMetadata} | rflAuftragsnummer | ${dummy_text} | |
Set Wsdl Object Attribut | ${object.commonMetadata.change} | version | ${dummy_text} | |
${result}= | call Soap method | setProductMetadaten | ${object} |
RFlog result
Creating 100X Request with RF For loop keyword
map WSDL local | ||
:FOR | ${i} | IN RANGE 100 |
setProductMetadaten |
Hope these infos help you starting your SOAP request creation with Robotframework & SudsLibrary, just another way of SOAP testing than using SOAPUI.
Custom PB4 (shorted)
Below PB4 adalah assesori nikon yang saya gunakan untuk pemotretan macro atau pemandangan.
Kelebihan dari below ini dibandingkan dengan below nikon yang lain adalah kemampuan untuk shift serta tilt, sehingga anda dapat mengatur DOF sesuai yang anda inginkan dalam komposisi gambar anda. Ini adalah solusi saya sebelum ada lensa Tilt & Shift dari Nikon.
Below ini di perpendek sampai scala 10 cm dari ukuran asalnya untuk mempermudah handling pemotretan.
lensa ini biasanya saya pakai dengan lensa:
- Below Tessar 50mm/2,8
- Enlager Lens EL Nikkor APO 135mm/5,6
- Olympus Zuiko Auto1:1 80mm/4
Dengan PS4 sebagai Slide Copy
Modifikasi lebih lanjut untuk dipakai dengan digital kamera silahkan dilihat disini
