Fantastic shots Pål! Yes, Velvia 50 really excels in these low light/dusk/dawn shots. It picks up the slightest accents of colours and really highlights them in an amazing way.

Hi Dave,

It's true that Velvia (especially 50) is an unforgiving film and any slight errors in exposure calculation can result in an unusable shot. What's more is that compressing your scenes into that narrow dynamic range (estimated 4-6 stops) from what is front of you usually requires a pretty thorough knowledge of when to use graduated filters and other tricks. But it has to be said that if you can conquer all these skills then the results truly are second to none! Without knowing too much about your set up I would suggest using a separate spotmeter and learning how to take correct light readings and calculating exposures. I would probably start this with a cheaper slide film and then practice until you have that nailed. Once you are in this position I would start on the Velvia 50 but still bracket half a stop either side of your calculated exposure. I still do this as I haven't yet reached the ultimate mastery whereby you know the film so well that you just need to take the one single shot knowing that you have the shot in the bag. As a footnote I rate Velvia 50 at ISO 40 on my camera (Pentax 67II) as it tends to give a more correctly exposed result on average. You might want to try both rating at 50 and 40 to see which you prefer and is easier to print/scan.

As for you second point it's quite an interesting one. I guess the ideal solution is that folk buy and use enough film regularly to make the equation workable for the photographer as well as profitable for the manufacturer. Unfortunately we don't have access to the second part of the equation but it would interesting to know just how much film needs to be sold in order for it to remain 'viable' for a company like FujiFilm.

Yep, obviously the best way to show Fuji you care is to continue to buy the film but I think it adds extra weight with a petition. There will always be nay-sayers/doom-mongers who believe these things never work... but they are probably the same folk who wonder why they never win the lottery even though they never bought a ticket :-)

The petition has reached it's initial target of 1,000 signatures and now has a new target of 1,500... currently they are at 1,162...

Hi,

Slightly off topic but there is now an online petition to save Velvia 50 which Fujifilm announced they will stop producing in certain formats (initially 4x5 and 8x10). The news was announced in the BJP: Fujifilm discontinues two professional films [update] - British Journal of Photography

The petition now has over 1,000 signatures including some high profile photographers such as Joe Cornish. The petition can be signed here: Change.org

Great, thanks!

Will try and pm him...

Yes, tuco, it took me many moons to track one of these down... eventually foundd one in a camera shop in London. They told me that it had literally been dropped off by the previous hour a couple of hours before I arrived. They hadn't even had a chance to put a price tag on it... They knew it would be picked up quick by a 67 owner!

Focussing a 55-100mm Zoom on a P67ii body

Hi,

I recently was fortunate enough to be able to pick up a 55-100mm Zoom lens for my Pentax 67 II camera. This is my first zoom lens for the camera and I'm very much looking forward to using it after hearing very positive things about its quality.

Most of my photography with the Pentax 67ii is Landscape work and my main lenses were the 45mm, 55mm, 75mm and 105mm. I expect the 55-100mm zoom to replace 3 of these lenses in my bag. However I have a question regarding how best to focus the zoom lens. As most of my work is in landscape I am almost always looking to maximize depth of field without losing too much sharpness. I found pretty much all the primes mentioned to be great quality even stopped down to f22. I couldn't really see any softness introduced by diffraction, etc.... When focussing the primes I would use the lens barrel to put the infinity mark just between 22 and 16 on the left side in order to maximize depth of field (assuming I had a shot which included a far horizon/mountain, etc).

Now my question is what should my technique be for obtaining maximum depth of field with the 55-100mm zoom? I don't believe I can now use the lens barrel to see what the limits of the focus are going to be. Should I now rely on adding hyperfocal distance 'markers' to the lens at various focal lengths?

Any opinions on what approaches are available would be much appreciated !

Cheers, Rick

Lee filter on a 55-100mm Zoom on P67ii

Hi,



Just picked up a 55-100mm zoom lens for my Pentax 67ii body. I know the filter ring is 95mm on this lens.



Currently I am using a combination of Lee and Hi-Tech filters (Grads, NDs, etc) in a Lee Holder with a number of adaptor rings for the previous lenses I was using. With this new zoom I am going to need a new adaptor ring (95mm thread) to attach the holder to the lens. I see that Lee don't make a 'Wide Angle' version of their 95mm adaptor ring. So I wanted to ask if anyone is using the Lee 95mm 'Standard' adaptor ring with this lens and if so whether there are any issues with doing this? (eg, vignetting, etc).



Thanks for any help!

Extension Tubes
Posted By rickbehl
Replies: 9

Thanks for the respons. I'll try and get out with the camera and tubes in the next day or two to try them out. A couple of thoughts and conclusions so far...

1) Seems best to use these for close-up/macro type work rather than trying to use them for the 'extra reach' (eg wildlife type images)

2) Looks like general consensus is that the tubes are optimally used with focal lengths in the range of 75-165mm (75mm, 90mm, 105mm, 135mm, 165mm) although of course they can be used practically with all lenses with maybe less than optimal results.

3) I think I get it now with the EC. When the manual says x2.0 it translates to 1 extra stop (ie, double '1' ONE time) and when it says x4.0 it means 2 extra stops (ie, double '1' TWO times). If I summarise the data from the tables in the manual I believe that as a rule of thumb to remember the EC:

Tube #1 (14mm) : Add 0.5 Stop
Tube #2 (28mm) : Add 1 Stop
Tube #3 (56mm) : Add 1.3-1.5 Stops

Again using the TTL meters obviously helps removing the need to remember these numbers.

4) Looks like there should not be too much loss of image quality as long as tubes are used individually and stacking is avoided. Generally it sounds like I should be using very small apertures to get maximum sharpness throughout? As f/22 may introduce softness it sounds like f/13-f/16 is optimum? Also, as noted and probably dictated by these shutter speeds a tripod sounds mandatory.Conversely using a tube with longer lenses should help to produce nice bokeh (probably good for portraits with the 165mm?)

5) A bit confused here. After a couple of tests it looks like the tubes do not allow the aperture modification to be used (pentax service centre mod to display aperture instead of the frame number in the viewfinder display). This is not a big issue really. However just so I am clear on how to measure exposure. It sounds like I cannot use Aperture Priority mode? And I'm not too familar with the term 'stop-down metering' (excuse my lack of knowledge here). Am I right in thinking the procedure for metering with these tubes are:

i) Switch metering mode to manual (ie NOT 'A' mode)
ii) Compose and focus the scene
iii) Set desired aperture for required DOF.
iv) Use the DOF Preview lever to stop down the lens to desired aperture and then set shutter speed to correct exposure (using viewfinder meter to get to Center Mark '0').
v) Press 'Meter Lock' to lock exposure or keep DOF lever locked at stopped down aperture. (However the P67II manual says that the 'ML' button cannot be used when the camera is in Metered Manual Mode?)
vi) Release shutter

Does that sound correct?

Thanks again for all your help!

Extension Tubes

Hi,


I have just purchased a set of Pentax 6x7 extension tubes on ebay. I have never used tubes before so I'm just trying to figure out a couple of things. Hope someone can help with the following questions...


  1. What scenarios lend themselves to using the tubes? Am I right in thinking these are best used for when you want to focus closer in on your subject almost like a macro lens. I am thinking these are not really designed to get longer reach which is what I believe Teleconverters are used for?

  2. Which Pentax 67 lenses are most suitable for using with the tubes? or is there no real limitations?

  3. What exposure compensation if any is required when using the tubes? Looking at the manual (http://www.pentaximaging.com/files/manual/6x7_EXTENSION_TUBES.pdf) it seems that for example using Tube #1 (14mm) on most lenses results in an exposure compensation of x1.6. Does this mean I need to add just over half a stop to my exposure (either aperture or shutter speed) to compensate for the tube?

  4. Is there any tangible loss of image quality when using these tubes? Is the effect cumulative (ie, more tubes = more quality loss)? As there is no optics in these tubes not sure about this...

  5. When using the tubes on a P67II body how is the metering on the AE Prism affected? And if I have the modification on my P67II to show the aperture in the viewfinder is that now not going to work when using a tube?



Thanks in advance for any help with these questions!

Actually from memory I believe Fuji actually state that Velvia 50 starts to need exposure compensation for reciprocity failure with a shutter speed as 'fast' as 4 seconds... I think it's something like a +1/3 stop at 4s, +1/2 stop at 8s...

I tried Velvia 100 recently on a trip and although I was really hoping it would be my 'secondary faster' film to it's big brother, Velvia 50, I was dissapointed to find that it exhibited some quite noticeable colour shifts (towards magenta) in white clouds and skies when I used some (Lee) Grad ND's... The same shot on the Velvia 50 showed no such casts... The Velvia 100 worked great when I didn't have to use any filters...

Although not everyone likes the 100F I don't believe it exhibits this 'cast' with GND filters...

Yes, it is unfortunate that a lot of our favourite films are slowly dissapearing... It's a real shame that film manufacturers are being forced to do this. But of course these companies are run as businesses and hence only really act on the the bottom (financial) line...

There does seem to be some resurgence about interest in film cameras that I have noticed on this and a few other forums. I think cameras like the Holga are helping to spark some interest in film photography. I even bumped into a young university student a few weeks ago who had invested in a large format view camera that he would use for landscape photography. I was quite impressed but unfortunately he told me that he was the only member of his 'camera club' that was using a non-digital camera.

I do believe that Kodachrome and Reala are being phased out from the list above. I heard that Kodak Portra is also going although will be replaced by something supposedly better...

Workflow for Scanning on Coolscan 9000

Hi all,


I guess this might have been asked before but if so please just point me towards the most relevant thread. I did a quick search but couldn't see any recent posts on the subject...


Anyways, I have managed to finally purchase a Coolscan 9000. My main usage will be to scan 6x7 transparencies (mostly Velvia/Provia) and also some negatives (B&W - Ilford, TriX, Colour - Portra, Ektar). I did have a Coolscan 5000 before and had some kind of workflow but I want to start again from scratch to create a new one. The old workflow was a little hotch potch and didn't always give predictable results. I do have Nikon Scan v4.0.3 and Vuescan already. I have managed to get the CS 9000 recognized and working under Windows Vista 64-bit (thanks to this incredibly useful thread here :


Unoffical Vista X64 driver of LS-8000ED/9000ED for Nikon Scan 4.03 - Photo.net Digital Darkroom Forum


So, essentially I am looking for a professional workflow to get from the raw neg/slide to a 'Master' and then a 'Working File'. Some initial questions I have:


  1. How useful for general scanning are the ICE, DEE, GEM, ROC functions? If not general usage, when would you use them?

  2. I believe it is always best to get a Master file at 16-bit, 4000dpi as the first step but these things weigh in at 550MB for a 6x7 slide. I don't mind storing this file in an archive (TeraByte drives are cheap these days) but what steps are involved in going from this to a file I can work with in Photoshop/Lightroom, etc?

  3. My initial experience is that Vuescan is a little slower than NikonScan with the CS9000. Is that the general consensus? I do appreciate having the ability to use colour management in VS (I have the Wolf Faust 35mm IT8 targets). Do people generally find using the IT8 targets helps obtain the best 'Original' colour rendition?



Thanks again,
Rick

That's a Great Shot Tuco! Love the blue skies. I take it this was just after the sun had gone down?

I've taken a few shots on Ektar but nothing serious yet... I still really enjoy the viewing of a good transparency on the light table...

Hi,


I realise the idea of a perfect film is very subjective but I thought I would see if there was any general consensus on the matter. Up to now for landscape and nature photography on 35mm and 6x7 I have been using a combination of Velvia 50, Velvia 100 and Provia 100F. My main shooting is geared towards the fairly low light levels (magic hour). I haven't really experimented with Kodak film for landscape (although I do use Portra as my main portrait film). I'm pretty happy with Velvia and my main decision between which of the 3 films mentioned I will use in any given situation is usually determined by the amount of light available (if very low then use Velvia 100/Provia 100F, if very bright then use Velvia 50).


My question is what is/are your perfect film(s) for landscape/nature photography? and do you use any combination of pushing/pulling on these films? Is my thinking right in that Velvia 50 doesn't handle too well for longer exposures hence Velvia 100/Provia 100F are better for very low light?


Thanks in advance,
Rick

Filters for Pentax 67ii lenses

Hi again,

I've now realised that with the collection of Pentax 67 lenses that I use I have a number of different filter thread sizes to accommodate on a shoot. Up to now I have been using the Lee filter system with ND Grads and Warming filters on the Lee Holder system. I already have the ring adaptors for 67, 77 and 82mm.

This setup is fine but I have a problem when I want to use a Circular Polariser. The only one I currently have is a Nikon 77mm CPL which I have from my 35m equipment. To use this with the Lee filters is a bit tricky as I have to mount the CPL on the lens and then mount the Lee filters on that in front of it. It's tricky because the CPL rotates itself when you try and screw anything to it...

Anyhow I saw that Lee recommend a 105mm B+W Kaesemann CPL to fit to the front of the filter holder kit. I have a couple questions about this:

1) Does it make any difference to put the CPL in front of other filters rather than behind ? (ND Grads, Warming filters)
2) How is the quality of the B+W filter? I have heard they are good (although expensive)

Is anyone using this Lee setup in practice?

Thanks in advance,
Rick

Thanks again. I think the Pro Trekker should be comfortable enough. Like you said it's hard to gauge without actually putting all your intended travelling gear inside it and carrying it for a mile or two... I don't think the shop would be too happy if I suggested that :-)

Anyway, I have ordered it now from Amazon so I hope it does work out!

Neester, yes, a couple of folk have responded to me saying that a dedicated backpack works best. But to be honest I don't think I will be hiking to location spots for more than a couple hours at most so I think a Photo-biased backpack probably works better than a Hiking-biased one. If the ratio of Hiking:Photographing was starting to skew more towards Hiking then I think you are right and I might need to reconsider...

Hi,

The importance of a good quality tripod really cannot be underestimated for any type of photography where light conditions will make hand-held shooting impossible without shake. You can use the 1/focal length rule as a rough guide to figure out the speed at which each lens should be put on a tripod.

I started off with a cheap tripod and pretty soon realised that if anything it was probably putting more 'shake/blur' into the image than I would if I had shot hand-held. Basically if you want anything which is half-decent quality it will cost you a reasonable amount.

Here is an excellent article on why it is worth spending the extra money on a good tripod: Tripods and Ball Heads by Thom Hogan

Personally I shoot landscape/cityscape/nature type stuff usually at low light (sunrise/sunset magic hours) and am using a Gitzo 1257, a Markins M-10 Ballhead and a Markins damping plate. This has worked well for me so far with all my Nikon 35mm gear (up to 300mm lens) and so far with the 67ii and lenses up to 165mm... I should be receiving a 200mm lens soon. I hope this set up can cope with that lens as I believe this is around the focal length where shake is hard to control....

Just a quick update... I was down at the camera store today looking at a few of the bags mentioned. Here's my initial thoughts:

Kata Bumblebee PL220 - Was told this was the new update to the HB207 recommended. Nice bag which seems very light. Nice and bright yellow inside making things easy to find. Rubberized straps for shoulders but not too much in the way of extra external storage

Lowepro Vertex 300 - Nicely constructed and design, looks robust but not really too much in the way of carrying anything aside from your camera gear/laptop (ie would be hard pushed to put any clothing/food/water, etc)

Lowepro Protrekker 300 - Probably the most suitable for what I am planning in that it seems more geared for hiking as pointed out by tuco above. Nice external storage options which all seem removable if you don't need them or want to cut down on weight. Also a side pouch for a water hydration system so you can have a tube coming straight out of that.

I think I'm sold on the Protrekker 300. It's probably big enough for what I want to put into it. Any bigger and I think it would be too heavy...
