Where to develop slide?


Btw trans are good for scanning too.

Hmm...no offence, but I can't say that's very true though.. From my experience, negs still give better scans. Partly because the wider latitude gives more data, especially in areas which are prone to overexposure such as skies. On the other hand, scanning slides has never been a very fulfilling thing for me.. The colours somehow always comes out slightly less than what I see on my light box. This slight reduction of colours and contrast has made me wonder if the added cost of shooting slides is worth it at the end. And I find myself digitally manipulating the scans to give me a "digital equivalent output"

The problem is that empirical data a.k.a. the many films I have scanned, is that negs often than not gives equal, if not slightly better scans than slide film which costs nearly double the price. Of course some may point out that slides has finer grain, more accurate colours, etc etc of which I do not object to, but if that is the objective, why not shoot digital instead? That said, I also understand that everyone has their own reasons why they shoot film and I'm not in any way trying to blow holes in them. :) Personally for me, I shoot film, mainly negs these days, (I used to shoot a lot of slides in the past, but it left me rather high and dry) for its wide latitude which digital cannot seem to match and its unique colour reproduction characteristics which is too much of a hassle to recreate in digital.

I dont ask alot,

may be 2 jug of beer I give you some clue??

:sweat:
 

allo allo, far more then that

No beer, No talk... hee hee

Haha.. I prolly know where you are getting at le.. if you drop by my area den I treat u drink beer la.. haha.. tiong barhu very far nei;)
 

I buy you 3 jugs of beer! Please tell me! :)
 

I buy you 3 jugs of beer! Please tell me! :)

on you guys..

When and where??

To all Rfer, got 5 jug beer to offer, RWC you can reserve some space for this. :)
 

A brief introduction:
Modern Scanner introduce in 1940 by PDI (printing Development Institute) Pattern belong to Kodak. Since 1957 Rudolf Hell and Crosfield UK start to produced scanner and at mid 70s Screen Japan also go into scanner business.

I was first work on C296 Hell Vario Chromagraph in 1976, some years later C299, Then Screen SG 818, Crosfield Magna Scan. In between I need to go through various system image processing too.
pic are search from web.

Original slide wil use oil mount on the drum wrap with mounting film.

Drum scanner use a very small spot of intense light beam through or reflected from the original copy. When drum rotates, the original is scanned by the light spot, when drum rotates. Resolution is also base on the aperture setting of the pick up lens and the advance line width.

After the pick up lens, light split in to 3 or 4 beam via beam splitter and pass through a colour filter RGB (some scanner use the 4th beam to produce USM signal.) and focus on a photo multiplier tube and convert to electronic signal direct to a set of colour computer for tone/colour correction and UCR or PCR/ICR/GCR USM detail enhancement. The colour computer is directly control via a set of keyboard and knobs, a set of variable data may be input to modify:

Size of scale
Resolution
Gradation control
Grey balance
Highlight enhancement
USM enhancement control with different colour gain /Fringe clip
Colour correction
UCR
GCR
Colour cast balance
Pasteur colour enhancement
Tone boost (Catch light/Hilight/Mid tone/Shadow)
Highlight / Shadow setting
luminancity

Data format usually is Run Length Encoding with own manufacture code. Save in 340 MB fix disc or 300 MB remove able disk.
 

haha.. drum scanners remind me of the concord moment.. great tech.. but nvr caught on.. jet planes were good enuf..

You need to read the highlight and shadow point to get most of the gradation out of it.
Have the colour reproduce as faithful as possible.

for negative, the density range is within D1.9 B/W or colour. The problem with colour neg is the base mask colour is different if type is different. You cant visual how the colour looks like,
only aga aga, colour correction setting will be critical.

Slide will be much easier, you visual with the image, enter HL/SD point, density range usually is around D3.2 - D4.0. Most consumer scanner sensor not able to read that wide range, you usually have problem with the shadow area and the colour reproduction.,

I use a microtek scanner for myself, I accept what is it thats it. I cant ask for more. Although I am very unhappy with that. hee hee
 

Hi,

I would like to know where I can develop slide film? Heard Fotohub doesn't do it anymore? That's where I used to go, and where many stores outsource to, so can anyone confirm?

TIA!

Go to the Fotohub Commonwealth branch, I think that's the HQ. If you send it to the other branches, the wait will be longer because they will all be sent to the Commonwealth branch to get done. The place is an industrial building but it is fine.

wa, very technical :thumbsup:

Roger sure does have a lot of knowledge behind!

I only know about fermentation, hops & yeast ;)
 

so the fotohub at beach road had closed down?

by the way, anyone has address of fotohub in commonwealth? issit easy to find? and may i know how much is developing a roll of slide?

thank you.

Go to fotohub website. Address is there. It's the building besides commonwealth carmart

How can you accept it after hearing your grudge at your house:bsmilie:
Maybe we can produce impossible project for E6;)
