Hey everyone
Just to weight in on the debate i was wondering what film brands people use.
I study, and teach photography, and this is an interesting topic of
discussion.I asked them at lunch on Friday, and these was there answers
If you want good quality pics, use slidefilm, best probably a Fuji one.
Best colour film , Agfa. No arguement
Fuji Velvia, and Superia both very good as well-have a blueish tinge
Kodak film plays tricks when overexposed, usually going very red or yellow
Konika, has poor lowlight performance.
Steer clear of the cheap custom made brands like Woolworths, or Kmart brand.
Try and match your developing place (minilab) with your film. ie if you have
Kodak film go to a lab which uses Kodak Chemistry.
Anyway, that is a educated view. These teachers develop around about 18
films a week, and all have studio experience. Anyway that is their view.
Please add your views.

Hi all,
As some of you know, we had a small social night last night (Saturday,
August 21) at my place. Even though there weren't many people, we still
had a great time, and we were priviledged to finally watch Narelle's
entire footage of her May 3, OK chase!
We were all in awe, it was a truly awesome sight...multi-rotational wall
clouds (up to 2miles long!!!), not one, but TWO 1+mile F5 wedges (with
the OKC one possibly being an F6, Doppler recorded winds of up to
318mph, but Narelle informed us that Doppler cannot record winds higher
than this unless they "push" it! Unfortunately, they didn't.) And of
course, 318mph is the theoretical F5/F6 cutoff). The damage was
incredible, seeing entire landscapes of mud and dirt, of which used to
be trees, grass & houses. I've never seen footage so close before, the
way the entire wall cloud + tornado was rotating...and the speeds!
Words cannot express it, one only wonders how Narelle felt while
actually being there!! (Yes, I'm insanely jealous, yet happy for you
Narelle!) There were some bright power flashes, especially on one of
the tornadoes that was being filmed at night..it litterally lit up the
entire sky + tornado!
The video has 14 different tornadoes (in about 3hrs of tape, but I think
it was spread out over about 8-10hrs all up). Again, I was just in awe
watching it, I've never even seen anything like it! At times, it was
even difficult to judge the difference between the wall cloud and
tornado it was so wide!
There was also some rather comical things said...for example as they
were about 600-700m from the tornado, they passed the doppler and
Narelle goes "it worries me that we're going pass the doppler..."
But the best part was what Karl said (her chasing partner)...when they
could no longer see the tornado as it was rain wrapped, but they were
about 500m away, and the dialogue goes:
Narelle: "Geee, you can't even see it anymore, but it's still
there!......are you going to keep going?"
*Karl takes off again*
Karl: "well, as long as we see a car in front of us that's still there,
we'll be right"
The number of people driving fast (towards the tornado trying to outrun
it) was rather alarming though...
None-the-less, with every tornado story, there's always tradgey, with
people losing their entire house being swept clean (the town of Dover
was wiped off the map by the second F5 wedge they saw, and they aren't
rebuilding it). And there were the many people who died, as well as
those who were injured.
We also shared photos, gorged ourselves on pizza, and there was
cheesecake (and ice cream, black forest cake and apple crumble, but they
weren't eaten...) for desert.
Thanks for those who turned up!
Anthony Cornelius

Great stuff Daniel, I use AGFA as well!!! We will see what happens when the
real weather comes in summer.
One things I was going to mention earlier is the possibility of perhaps
ASWA in the future purchasing equipment to develop photos!! This can be
discussed but it is a long way off. I would suppose if we could get some
university or lab to use this form of sponsorship for ASWA... If someone
can arrange something, I will be keen to hear from you. Perhaps even if a
chain of stores that can realise cheaper development prices for ASWA
members and treating out photographs with special care. Surely some people
have contacts???

Daniel and others,
There has been a thread running in another list I am on regarding the best film
to use for lightning photography. The general outcomes of this tread were
exactly as you put eloquently into one email Daniel :)
For my photography I use a medium format camera for all my lightning shots and
use 50 ASA slide film (Fuji chrome Velvia).
I have used Kodak but not anymore. Slide film is by far the best medium to use
as it is clear with no graininess and the colour reproduction is very nice.
This photo was taken with this type of film
http://strikeone.com.au/pointoflight/pfl.htm
As far as the clarity of that photo goes there has been a lot of intentional
image degradation placed on the scan for the purposes of web page displaying but
the colour blend is as it is in the original photo
The following photo was taken on Fuji reala 100 ASA negative film
http://strikeone.com.au/sss/sss.htm
There is a lot of difference in the quality of the original between these two
photos as well as the general colour reproduction in them as well.
Just my 2 cents to the thread
Regards

Chas replied privately to my last email. They seemed like appropriate
questions, so here goes:
> I think the digital camera does a fine job.
> What prices are they these days? The last time I saw a price must be 12
> months ago.
Not sure on prices. I paid a discounted $2000 at Chatswood about 9 months
ago.
> If you want a hard copy and do not have a quality printer are they easy
> to do?
At present there are not too many shops that can offer printouts.
They usually charge a flagfall per disk but the price comes down if you
happen to want multiple copies - like many many..
Many commercial copiers do rather nice prints but you may have to check
whether the final result needs laminating because the surface is a little
chalky.
However A3 colour printer prices are dropping rapidly.
At the moment I have no simple way of printing pictures, but I rarely have
the need, since I distribute my pics over the net.
Using a digital camera requires a big rethink on how you take pictures and
what you do with the images.
> Are they as good as what appears on the screen?
Should be every bit as good if you do it right.
> How many photos to a floppy disk?
Varies tremendously. At 1024x768 res I can get from 7 to 33 pictures onto a
floppy.
This is because the images are stored as jpg, which are compressed. The more
detail the bigger the pic.
File sizes range from 35k to 150k.
Another wonderful feature of a digital camera with an LCD screen is that you
can see exactly what you're taking.
Therefore if you have a bright sky and a dark foreground you can move the
camera to optimise the range of light variances.
One drawback for ALL digital cameras (as far as I know) is a slight lack of
latitude. This is the capacity of a film to capture bright as well as dark
areas on the same shot. The Mavica seems to be roughly equivalent to taking
pics using 400 ASA film, so you won't get the luscious tones of 25 ASA slide
film.
Two grand seems a lot for a camera but I don't regret the purchase one tiny
bit. I've so far taken thousands of photos.
I also have a regular IRC chat session with a group which discusses
geometric model-making.
When I want to explain a point or show a new idea, I simply take a couple of
shots and load them immediately to a website.
The turnaround time is about two minutes. The effect is quite impressive.
Another cute idea is to take a timelapse series when I go for a walk. I take
one picture every 20 paces or so, always looking straight ahead.
I use 640x480 res so I can get about 50 pix to a floppy.
After loading the images to my PC I run a rapid ACDSee slideshow of the
sequence, which almost turns it into a movie.
Next time I get the chance I'll do a cloud sequence and put it onto a site
for the aus-wx group.
Note: ACDSee is an image viewer program - easily found at most shareware
sites.
Hope this helps.

There is no doubt that Digital cameras are getting better and better, and to
be honest because your scanned conventional camera pics have to be JPG
compressed much of the quality difference is somewhat neutralised. No one
would argue that conventional film has a resolution that digital can only
dream of. But this is only a real issue when you want to enlarge photos or
sell them. For everyday web purposes the digital is looking good, especially
for the accurate colour reproduction.
There is a new digital format called SLR digital in which you can use
conventional lens, this is interesting.
The pics on your page, is that the size that comes from the camera, or have
you compressed further ?

Hi There,
Welcome to the fifth edition of the Australian Severe Weather Association online newsletter. I hope you all enjoy it and any thoughts or comments can be send to " Kathryn Jolly at astroman at chariot.net.au " also please don't forget if there is any information regarding the Australian Severe Weather Association that you would normally send to the list, please send it to me instead for inclusion into the newsletter. That is what it is here for.
Happy reading
THE AUSTRALIAN SEVERE WEATHER ASSOCIATION INC WEEKLY NEWSLETTER -Issue 5
The Australian Severe Weather Association Inc (ASWA) is here to provide a platform for discussion into severe weather, research and education. A lot has been written about about Australia's severe weather in the past and you can view many different stories of people's experience with the weather in the offical ASWA magazine "Storm News". Discussion about the latest weather and a great place to learn from is the aus-wx mailing list from which ASWA Inc was originally formed. The mailing list is filled with people who are eager to help teach others about all aspects of meterology and to share their experiences.
Membership into the ASWA Inc is $30 a year (with access to the Bureau of Meterology's radar and a quarterly subscription to "Storm News) or if you don't wish for radar $20 a year (with the quarterly subscription to "Storm News" still remaining.) Both visitors and members are welcomed to attend State Meetings. State Meetings are held in Western Australia, South Australia, Victoria, New South Wales, and Queensland in their capital cites. Members can also have the chance to buy an ASWA T-shirt in either polo or round neck styles. If you would like to join you can visit the ASWA Inc website at http://www.severeweather.asn.au/ and fill in an online application form or get in contact with your State Rep. All details can be found at the website.
General News
Looking for new members - try this
The SA/NT division hasn't been apart of the ASWA for as long as what other divisons have so their members are few and far between. It only takes 2 members to give apologies and their meeting is cancelled for the month. This happened for the first time last month.
It was discussed once at a meeting how to try and let people know that the ASWA exists, and not very many ideas arose. Kathryn was on the IRC the other week, when she decided she would attend #adelaidesa a place she knew would have a lot of adelaide people in it. Just after she joined the channel she put up a message saying "Who here is into severe weather ie thunderstorms, cyclones etc etc" a few people in the channel said that they were so she privately messaged each one. After her first attempt at doing this she has one person who has a love for tornadoes very interested in the ASWA and who will look into becoming a member very soon. This person is now in regular contact with Kathryn via #weather and is looking at attending our next months meeting as a visitor to check it out.
Each capital city in Australia seems to have its own IRC channel, and if you are a regular user on IRC it only takes 5-10 mins to pop in to your capital cities channel and ask if there is anyone into severe weather. If someone is interested privately message them and ask them about the type of severe weather they are into and then have a general chit chat. You can then bring up ASWA, if they are interested in finding out more about the ASWA you can then give them the URL to the website so they can check it out for themselves.
New Section - Weather News
As you all know Storm News has all the stories about the severe weather and storm chases that have happened around Australia, and is beautifully put together by Anthony and James every 4 months
Somtimes there is a heavy rainfall or a storm chase where nothing eventuates but you just want to mention it to someone, you may even like to say how sunny it has been all week, if that is the case then this segment is for you. I will allow one sentenced weather details (ie Adelaide had fine and sunny conditions all week with top temperatures hovering in the low 20's) which you aren't meant to do on the aus-wx list, and try and keep stories to no larger than approx 2 paragraphs, due to space and download times of this email.
Each state will have it's own section similar to what I have done with meeting times and locations. So don't forget to tell me what state you are situated in and the area of your Weather News.

Personally i use Fuji Velvira or superia film, I dont think that AGFA is
too bad as well but id certainly never buy Koadak again. On the thought of
colours etc i have enclosed a portion on film brands by Chuck Doswell whom
has always been at the forefront of storm photography.
"The color shift can develop with color films because color is obtained in
the film by exposing 3 different light-sensitive layers in the film. Proper
color balance depends on these layers reacting to light in a well-defined
way. Under reciprocity failure conditions, the three layers respond
differently (that is , not in the standard way). Most films offer a linear
response over a range from 1 second to about 1/10,000 second, a remarkable
range of 4 orders of magnitude. When you get outside this range, one or
more of the layers begins to exhibit a non-linear response to light. A
layer might over-respond to light (doubling the light produces more than
twice the brightness) or it might under-respond to light, while the other
layers continue to respond as before, or perhaps offer a different
non-linear response. [See note below] The result is that the three layers
are no longer synchronized, which results in a change in the apparent film
speed for such exposures, and a color shift. If all 3 layers were to hit
this non-linearity together and they all exhibited the same nonlinearity,
all that we would see is an apparent change in film speed, rather than a
color shift. I've found that Fuji Velvia is relatively resistant to color
shifts with long exposures."

Do you have any suggestions on how far you shoul set the light meter
readings for different environments? I was originally going experiment
with that, until Paul M. swore black and blue that I should just invest
in getting a polariser lens (for very bright pictures).
We (ASWA) should organise a proffessional photographer to talk at each
state and advise what film & settings they personally use. WA have
already got it easy with Mike Fewwings and Nick Djorvic (spelling) to
assist them.

Hi everyone,
Hi Jimmy here,
Whilst at the weatherwatch meeting, it was brought up by Laurier that there
should be some research into the more misunderstood aspects of snowfalls in
Australia, particularly the historical aspects. So I would like to
re-iterate this message to people on the list and/or ASWA.
Are there anyone who would like to take part in this project?? I know Tim
Crugeon is keen to get started. I would like to see some of the more
experienced people taking the leading role if they have time such as
Laurier, Don or Michael Scollay but really anyone can do it. This is an
important and ongoing project and will take some doing. If you would like
to be involved because you just love snow etc and would like to find out
more, contact Tim Crugeon
Tim Grugeon
At this stage, it is up to those in any state to join in if they wish and
organise themselves. You have been given this opportunity so I won't be
getting too involved with it.
Jimmy Deguara
