Menarik..

[marowi]

Bgus dan manarik. Kalau boleh kongsikan dengan member yang lain cara gambar tu dieditkan. Kalu minat nak edit lagi saya ada banyak imej B&W yang diambil 2-3 malam yang lepas

Assalamualaikum

Saya ingin bagi pendapat sikit. Foto asal yang diberi adalah dalam versi BW. Jika diambil dalam RGB (atau warna), saya amat yakin bukan setakat merah sahaja yang nampak, malah tone warna lain akan wujud.

Contoh untuk Horsehead Nebula, jika perhatikan koleksi di internet , kita dapat lihat kombinasi banyak warna, merah, kebiruan, purple oren dan lain-lain.

Oleh itu, andai kata kita buat colouring supaya ia jadi selain dari B&W, bukankah ia memberi seolah-olah gambaran 'palsu' terhadap ciri warna sebenar objek tersebut?

kosmetik purpose tapi tujuannya ape? 

perhaps anyone can enlighten me.. mungkin ada benda yang saya ter-miss..

persoalan ini telah saya tanya lama dahulu semasa saya mula-mula berjinak dengan astrophotgraphy dan telah di jawab olih sifu disini dengan isu "false colours". Gambar yang di rakam dan di process ikut selera dan imaginasi pengambar. 

Beauty is in the eyes of the beholder. Nasib baik ada persetujuan ala pertandingan miss universe.

Jadi gambar-gambar di universe pun sama

Malang nya di sebabkan semasa migration of the various severs dan perubahan format kepada FO ia nya lesap.

Lihat dia punya interpretation dengan gambar terkini M45. Kalau di poskan di FO tentu ramai yang tak setuju

Lain2 bolih bincang semasa TT

cheers

Nampak cantik sangat-sangat. macam painting pun ada. very nice!

[universe24]

M45 tu sepatutnya tiada masalah. M45 tu masih dalam warna yg hampir dangan apa mata kasar kita boleh nampak (kalau cukup sensitif).

Warna sesuatu deep sky object memang agak subjektif, hubble buat M16 nebula dalam warna hijau...tiada org kata itu palsu punya...
Asalkan pada keseluruhannya sesuatu gambar memberi impression, then is ok.

Does colourizing a B&W photo included? If we capture using monochrome cameras and use the RGB filter, and later combine .. then I would say the output should be a more 'correct' because we have LRGB datasets..

But if we have only one data set, in my case, B&W, and then add colour to it.. will that be accurate? 

Agree that Deep Sky colours are very subjective and different people will have different perspective, in case at one upon a time, long time ago,  one member commented that some of the photos taken are too 'photoshop'-ed .. I'm refering to the colour issue here..

this has been addressed by many international astrophotographers sifu.

the consensus is all are correct 

The cookbook is here and

colour enhancement technique is here

and the different results are(scroll to the bottom of the page) here
with examples shown for Cone, Horsehead,M42 and M1 nebulas.

But if we have only one data set, in my case, B&W, and then add colour to it.. will that be accurate? 

Is black a colour and or is white a colour.The students of  physics  will say black is not a colour whilst white is. Photographers will say black is a colour and white is not(maybe)

When using a CCD/CMOS a 1sec exposure and a 56 sec exposure is different. Take the case of M42 that you shoot with the mallincam.
You then blend the series of exposures into a HDR to form the image which to you is correct. After all it is from you own effort

But then again I recalled the M42 taken by sifu william from sungai buluh using the Hyperstar with C14. It certainly is different in colour from yours.

Hence there is no correct colour other than what we have been preconditioned by various images taken by others.

It is all in the perception.

jd adakah bermakna lain gear lain color kita akan dpt?

I would say the colourizing is acceptable for me. If the final result is very impressive and wonderful.
As I am not a well colourizing expert, then I prefer to capture the "colour" from the object.
Some member think those photo taken too "photoshop", this might due to they do not understand what is photoshop and also what is called the digital dark room.
What we can do is to explaint to them how we do it and why we can do it. There is something we can do and something we cannot do in photoshop.
All this must based on the side of moral & ethic.

Ya, ada sesetengah teleskop akan ada warna tambahan kat bintang-bintang yang dirakam tu di mana dipanggil color abberation.
Dulu semasa guna film untuk photography, warna gambar juga bergandung kpd film punya sifat.

ok understand.. i rest my case

[amahir]

You dont see with your eyes, you perceive with your mind. 

btw, apa kabar dr?
wah cantik betul gambar ni.. boleh la ltk dlm buku dr nanti

anyway, tunggu kehadiran sy bulan 6 utk mengacau mlm2 dr.. hehe

[marowi]

Amahir,
Tunggun bulan 6 lambat lagi. Patut sekarang, ambik cuti la cuaca kat KB baik hampir-hampir every night.
Bulan dah mula hujan malam
rowi

Maaf Mahir, bulan 6 dah mula hujan malam.
