Re: Απάντηση: RED one David vs Goliath?
Χμμ.. Διαβασα καποια ασχημα reports στο
Avsforum:
Απαντω σε οτι μπορω απο την μεχρι τωρα μικρη μου εμπειρια με την καμερα.
Την επομενη εβδομαδα θα κανω το πρωτο μου γυρισμα οπου θα μπορω να εχω πιο εμπειρη αποψη.
My day job is shooting Television, which I've been doing for 27 years and thankfully it doesn't involve typing. The reason I'm adding to this discussion is because I recently finished my first project with a Red camera. It was a spec commercial for energy conservation and CFL (compact florescent bulbs). I have some time free tonight so I felt I should reply with some first hand information based on my experience.
I'll start by saying I didn't pick the Red, it was chosen by the producer. The camera has had a lot of buzz and I went in with an open mind.
There's so much to say, I probably should try to organize my thoughts into something logical. But I'm going to let it all pour out in a ramble. Which is not unusual for me.
To begin, I didn't find the images to have the amount of information typically found in 4K. I'm not sure what was going on. It reminded me of using photoshop with an HD image and using the resize tool to blow it up about 400%. This was disappointing, but not unexpected considering the cheap price tag.
Πρωτα απο ολα για καποιον που δουλευει τοσα χρονια στην τηλεοραση ειναι φυσικο να τα βρει μπαστουνια με αυτην καμερα.
Δεν εχει καμμια μα καμμια σχεση με τις υπολοιπες βιντεοκαμερες SD η HD.
Μονο και μονο οτι τραβαει RAW κανει τον τροπο που πρεπει να την χειριστεις παρομοιο με αυτον που τραβας φιλμ 35μμ.
Η αναλυση της ειναι κατι το τρομακτικο σε συγκριση με οτι εχει δει κανεις μεχρι σημερα απο σενσορες.
Το μονο που μπορω να υποθεσω για τις βλακειες του τυπου ειναι οτι δεν ξερει να χειριστει το REDcine τον colorcorrector της καμερας και βλεπει τις μικρες αναλυσεις ....
My long time friend served as the editor of this commercial and he tells me the Red workflow was, "a real pain". I didn't get the entire story, but it was a good long time before he could get images out of the Red software. When he finally did, the images were unsaturated and the blacks weren't black. After playing with the images for a long time in color correction we were able to get something usable.
Μονο και μονο αυτα μου επιβεβαιωνουν οτι προκειται για ατομα ασχετα με την διαδικασια του color correction....
Eγω που ειδα τι πραγματικα μπορει να κανει το software στα raw της καμερας εμεινα αφωνος.
What was unexpected was the hard drive that records the images didn't seem very reliable. The camera conked out three times while we were shooting. Each time we had to re-boot and wait. It made me particularly nervous. The shutdowns were happening during the last shot of the day and the sun was quickly setting! The camera was mounted on a hood of Honda, and after the first three takes we found it was quite impossible to shoot with the hard drive. We then had to switch to compact flash cards, which worked, but we had to reload after only 3.5 minutes of shooting. Re-loading with the sun setting was stressful. It was clunky to say the least.
Σε αυτο ειναι το μονο που θα συμφωνησω εν μερει μονο.
Η καμερα ακομα μπορει να κολλησει και θελει reset αλλα μην ξεχναμε οτι τα firmwares βγαινουν ακομα βροχη και πραγματικα η καμερα ειναι ακομα υπο εξελιξη οσον αφορα το λειτουργικο της.
A 35mm sized sensor is nice, but lacking that feature has never been a deal breaker. I don't remember anyone coming out a movie like Zodiac and saying anything about depth of field.
On this commercial I was using zeiss ultra primes, good lenses. When compared to zeiss cine digiprime, the B4 lenses are much better optically than the 35mm ultras. I think it was probably a mistake to have a 35mm sized sensor in the Red camera, because none of the focus marks on the lenses lined up accurately. Since all cine lenses like the ultras don't have a backfocus adjustment, my AC had to focus by eye the entire day. At one point he got really heated when he coudn't get focus on the leading lady during a particularly difficult pull. The marks were off and no help at all.
The owner of the camera is about 20-years my junior. He came out as the camera engineer. He didn't own any lenses, and didn't know how to fix the flange depth problem.
Οταν εισαι ασχετος με την διαδικασια του γυρισματος με φιλμ και εχεις λιωσει τοσα χρονια στην τηλεοραση ειναι απολυτα φυσιολογικο να σου φαινεται βουνο το focus σε αναλυση 4k.
Ακομα κι εγω τα βρηκα μπαστουνια μιας και δεν υπαρχει οπτικο viewfinder οπως στις 35mm .Μπορεις ομως να βασιστεις στις παραδοσιακες μεθοδους focus που οι τυπακοι φαινεται να αγνοουν.
Above everything else the biggest problem we encountered was that the script called for our hero, a stressed out and tired housewife, to turn on a standard household lightbulb. The bulb was supposed to pop and leave her in the dark. The lighting gag we rigged caused a quick flash and sudden darkness. But the camera only saw the flash as a small streak horizontally across the frame. I've never seen anything like this from any camera. It's was really odd. In the end my friend the editor was able to more or less fake the gag in post. It wasn't what I hoped, but at least the client is happy with it.
Based on this experience I found that the Red camera doesn't have anywhere near film dynamic range.
Αυτο θα σας το δειξω σε ενα τεστ αργοτερα .....
Δεν ειναι φιλμ αλλα το ευρος εκθεσης της καμερας ειναι μεγαλο......ΠΟΛΥ μεγαλο.
If someone asked me to use the camera again I would probably tell them that call the Red is unusable for professional work right now. I hear Red is already working on their second camera. Hopefully the new camera will fix these problems.

Μεγαλυτερη ανακριβεια απο αυτη δεν υπαρχει.
Το να αντικατασταθει μια καμερα που ακομα δεν εχει τελειωσει ειναι ραδιο αρβυλα απο τις πιο κουτες. Ακομα δεν εχει βγει ενα firmware που να θεωρειται τελικο κατα καποιο τροπο.
Φημολογειται -απο την αρχη ομως, πριν καν βγει η πρωτη καμερα - οτι στο μελλον θα μπορεις να αλλαξεις μονο τον σενσορα.
Τιποτα αλλο.
Αλλωστε αυτο ηταν παντα η αρχη της φωτογραφιας: ενα αψυχο κουτι, ενας φακος ενα φιλμ η ενας σενσορας πια και πολυ ορεξη για δημιουργια.
Ολα τα αλλα ειναι δικαιολογιες.
