Sorry my poor explanation... I only purchased the full ND in the circular ones.. i found they trapped the light better. Between the lens. Than the rectangular ones. I found 3 stop, 6 and 10 were all I ever required. I havn't purchased my Grads yet. As with the DFA 15-30 they require a 150mm squ...

Thanks both, I will bank the seven photos that both advisors liked and maybe revisit some time in the future. Thinking back over the day it was clear that yesterday’s advisor struggled with anything “artistic” and when someone’s submission for such a category had been previewed by a specialist in th...

RPS Distinctions
This sort of thing is common in all walks of life. I edited a book a couple of years back and one of the papers I thought was the weakest was recommended as the most outstanding one in a review of the book. One has to take the useful parts and ignore the rest and, as hard as this is to do, not take ...

Now i have calmed down, retrieved my report from the bin and stuck it back together I recognise that technical matters in regard to the making of prints were valid and useful. I am sure I have come across the advisor before somewhere and I think he works for Photospeed but I could be wrong; however...

Flickr down for hours now
I can see Flickr on PC, but it's not working properly, I keep getting " bad panda" thing when I try to upload, but then later , stuff is showing up. Contacts seem to have disappeared too. Hopefully it's back up properly soon.

MPB cameras etc.
I bought a body from them a couple of months back. I would say the condition is better than the description. No complaints here, and based on my sample size of one I'd happily buy from them again :)

My Video -- 'Should I Join a ' Camera Club?'
Very good Peter. Did the recording cut off before the end? I was a member of the Ilford Photographic Society in the 70s & 80s so maybe we both competed in some of the inter club competition at that time. I've got a collection of red stickers on the back of some of my prints too!

My Video -- 'Should I Join a ' Camera Club?'
Regarding Ilford Photographic Society -- I went to Judge there once on my lovely Austin A35 Pea Green and when i came out it had been STOLEN from outside the hall --- an Ilford Member took me to Ilford Police and I think gave me a lift back home to Brentwood -- car was found 3 days later -- it had ...

Yellows and Reds
It's probably due to brighter shades of red and yellow being out of gamut on monitor displays. Underexposing and bringing back in the edit may help. Certain lenses are also known to handle these colours better for flowers etc. One such lens is the Pentax-A 35-105 see .... Evening walk with th...

Forced to use tav for studio portrait
Do you need to change focus regularly? If it’s a still-life tripod shot then you can manual focus with live view rear screen at a reasonable brightness, and then swap to your manual mode for the actual shot. If it’s flash based, and you need to focus each shot individually, then yeah I can se...

Forced to use tav for studio portrait
Also, have you tried changing your metering mode to spot? Random point, but from previous moon shot investigations the metering mode influenced the rear live view screen exposure, even when in full manual M mode for the actual photo shot. In my case setting this to spot would allow the moon t...

M42 adapter
There's two types, the first one allows for infinity focus and sits inside the K mount of the camera, and is released by pulling back a little spring. The second (cheap) adapter is about 1mm thick and covers the k mount contacts, this version restricts focusing to infinity. The first option is...

M42 adapter
If you're not mounting a normal lens, then I wouldn't worry about it lining up, since it doesn't matter so much. However, I'm not sure what the impact would be of using the cheaper option adapter that's 1mm thick and covers the contacts, whether you'd still be able to achieve focus. May be someon...

M42 adapter
there is a rare kood adapter that fits inside the k mount for infinity focus and has an internal flange that actuates the aperture pin on the lens.

M42 adapter
As much as I read comments about cheap adapters providing infinity focus, I'd be more concerned about getting the adapter stuck on the camera. Not too bad if it's an old 'cheap' film body, not so great if it's an expensive DSLR. The genuine Pentax one is the only one I'd use, irrespective of the ...

M42 adapter
If you have fingernails you can shove one of them in the slot to get the same result. I use the corner of my thumbnail. Derek, for a microscope I presume you won't need infinity focus. Consequently, you can use any of the cheaper, simple flange type adapters that have a normal K type bayonet on th...

M42 adapter
I bought an M42 adapter a couple of years ago for a telescope attachment but tiny flecks of the black coating got onto the sensor and even behind the focus screen. A devil to remove as it was static so I would always now look at uncoated versions which I imagine the Pentax one is.

Our eyes
My optician thouhgt I had PVD a couple years ago as the focus in my left eye detirioated suddenly. It turned out I had a cataract which has since been operated on. The plus for me is I no longer need glasses as they correct your vision with the new lens they insert
