Be very careful about leaving UV filters on full time. They can get fogging just from change in room temperature and before you know it you have fungus on the lens.
I never leave them on full time.
A good regular thing to do is place the lens on table outside facing the sky and let the light pass through them with aperture wide open.
I still have a Nikon F4s here I never use anymore ,but I still get it out and sit it outside facing the sky,I should sell it off but it has sentimental value to me

Luke chapter 9 verse 35

One thing that near killed photography for me when I did my Diploma at UTS, Was the maths ,it's extreme and people that had the HSC could not do the Maths and I had no chance because I left school at 14 . Now I was being told a rainbow is not a rainbow it's a visual display of dispersion and I need to know the maths on why it happens,plus volumes, vignetting,lens destortion, focal points from the Air etc .
Anyway I got really upset and depressed because I couldn't do that ,hell if HSC people couldn't I had no chance.
But it was only maths that was the problem and everything else I was doing well in.
I was just about to throw it all in and give up when one of the lecturers approach me and offered to teach me maths after class so with his help I learnt the maths ,I had no chance with out him ,hell I didn't even know my tables haha. See there is really good people out there!

I wasn't strong on maths at school. It wouldn't have mattered how much they tried, I just didn't want to do it and even later in my years at tech I only ever got into the 50s for calculations subjects but got into the 80s and 90s for practical subjects that actually tought me things I still use today. For the rest, there's always an electric brain (a calculator).

Brad,
I don't hide the fact I left school at 14 and so you can imagine sitting at UTS doing the maths...I knew nothing other than Basic maths but this guy pulled all stops to get there and in my exam I got 84% all thanks to him.
Ask me to do it today,,no chance

Pete what’s the difference between the Nikon f4 and the f4s? The Nikon f4 camera’s were incredible for the time! 4 frames a second! A lot of lower end digital cameras can’t to that and the Nikon had to advance the film!

Motor drive was faster in the F4s no other difference.
Yes they were $4500 body only when first released. So in the 90s that was a lot for a camera. I was sale Tax exempt in those days though, All registered Qualified photographers could be saleTax exempt ,but I never paid for the 4f body only the lens systems.

Maths was my worst subject at school but you might be surprised how it comes back to you when you need it for something in which you are interested. When you can see a USE for it!

In the late 60's and early 70s I was doing the E&C cert at night. Because my HSC maths pass was poor, I needed to do catch-up classes. Calculus in particular.

At the same time I was reading up on colour TV (it was coming and I had to be ready) about horizontal deflection systems and they were talking about 3rd harmonic tuning vs 5th harmonic tuning. Clear as mud, eh?

Well, when I realised how you could model a horizontal deflection system with a 2nd order differential equation, I was hooked! It REALLY helped me to develop a love of design and my career morphed from the service industry into design.

No-one's picked up on my cheeky biblical reference? Pete, I'm not being sarcastic!

When was the last time you put some film through it?
I mainly shoot 120 film but I like to take out the 4x5 camera for my own amusement.
Why do I shoot film? Well I get a kick out of it and I love the chemical process! The same question could be put towards why I like vintage electronics and it’s really just because I get joy out of it and it’s great to see how things were once made.
I’m definitely the type of person who would buy some silver nitrate, coat some glass and have a crack at my own emulsion.
I haven’t had access to the darkroom for three months because it’s at my grandads house so I can’t wait to get back in.
Pete I’ll send you a photo of some of the film I have in the fridge ready to go for when it warms back up again

In good light a 7D can do just over eight frames per second. They have a huge buffer memory - even better than the 5D at the time they came out, though since then I'd imagine the 5D has caught up. The 7D MkII can do ten frames per second. It's a good thing that the mirrors and shutters handle well in excess of the guaranteed number of movements otherwise shooting in rapid fire would wreck the mechanisms.

Pete, I can't say I've ever had issues with fungus on lenses though I suppose that doesn't mean it's not possible. My only issue with my kit is that I don't use it enough. I used to do a lot of landscape photography when I became interested in having a good camera but since then my interest has waned but one day it may bite me again. Hard to believe but about ten years ago I even lost interest in radio collecting for a period of around 18 months - that could almost be regarded as a terminal illness.

Ohhhh haha. Not since my divorce Lance, haha tends to mix up your life a bit haha,
But I'm with anther lady now for the passed 7 years.
If your doing darkroom and 120 see if you can find a bessler Enlarge with dial in filters.
They don't get any better than that.
If you find one ,I have some enlarger lens for 120 in box here somewhere you can have.
I won't be using them again .
The camera I loved the most was my Pentax 67 TTl finder. To this day it has produced the best images of all my work. The 6x7 format is beautiful in every detail.
The optics on them was perfect and this why we all used them .
Plus lens were 5k to 10k each so what you didn't have you hired from L and P.
The other thing I mention is ,don't get hung up old idea's of technical correct images, make your own style the world has enough old technical correct images that can be a bore.
Send me some photos ,no naked hotties I'm depressed enough here!

This shed can adapt to a darkroom as it has no windows. The previous abode had a dedicated darkroom; With a custom made wet bench of fibreglass incorporating the sink; all spillage went to the sink. Enlarger was on a dry bench on the end of the wet bench and the dry benches behind me. Work flowing in a logical direction. Building was long and low so the light switches were above my head at either end. The room was force vented.

The venting was as a result of knowing what was in the reagents and I worked in chemicals. Air entered enlarger end, & vented sink end. Naturally the (not town water) was filtered into the hot & cold water. This also had additionally, one of those flexible hand held shower heads for tray, bench, & machine parts, pot plant & radio bits, washing and was ideal for washing the farm kelpies especially as it was not cold water and they just loved the attention.

Ian, yes I spotted it , thank U,but I actually thought it was going to be ,let there be light"
Ian that the maths involved in electronics, particularly Television would be extreme as well. When ever light and images come together you can rest assured the maths are going to be a pain in the ass.
But I don't think I would of retained my maths knowledge due to the fact I never do any maths anymore so the brain has probably put it in the bin.
