Variable ND Filters and Metering problems
I have a 62mm variable ND filter from 7 Day Shop. I suspect you might have the same one, though. I haven't noticed the under-exposure problems, though I have noticed a bit of a colour cast at the darker settings as you have. I haven't really noticed any distortions, but haven't used that much either...

Variable ND Filters and Metering problems
I also have the 7 day shop variable ND filters and have had good results with them. You do lose a little sharpness, but the only colour cast I have noticed is a slight warming effect which helps to bring the colours out. The best advice I can give is not to turn the filters too far to the max, oth...

Variable ND Filters and Metering problems
I've just sent back the 77mm version from 7Dayshop. I have the 62mm version and had slightly more success with that. It could well have been me and not the filter :) 77mm ND Tamron 10-24mm on K5. Help :shock: #1 #2 #3 #4

Variable ND Filters and Metering problems
@ tyronet/ Stan Unfortunately, those dark bands are a feature of this type of variable ND filter. The wider the angle lens, the worse the banding. It means that widening the lens angle means that the amount of 'stopping' you can do reduces. I have a 67mm one from 7dayshop and nearly sent it ba...

Variable ND Filters and Metering problems
Stan, the banding your images exhibit are caused by turning the variable ND filter too far to the maximum setting. Tweak it back a little and these bands will disappear. I know that many will say 'what's the use if you can't set them at maximum', but to be fair these filters are not expensive and ...

Variable ND Filters and Metering problems
Hi Stan, the best way of focussing I have found is to use Live View. Even with little or no light, Live View presents a pretty good image and enables accurate focussing (BTW, this even works with an Infra-red filter attached which cuts out even more light). With regard to the filter and shutter sp...

Thanks to this thread, I think I will have to invest on the ND filter I saw on Amazon.

Prints haven't got the same 'pop' as on screen images
Vericolor wasn't just for wedding photographers... being Kodaks only C-41 Pro film (Extacolor old C-22 process was discontinued in 1975) it was for all Pro work including portraiture and commercial work where the shutter speed was 1/10 sec. or shorter. I'm quite sure it was available in all formats ...

Is This A Common Problem?
As a rule, you should always use the lowest ISO setting compatible with the available light. I don't understand this 'rule' What do you mean by compatible, or more to the point, what ISO would be incompatible to the available light. I've used ISO100 in moonlight for long exposure nightshots....

Hey! that looks like the inside of my car! :shock: :mrgreen: On the building ADIA is the wall like that or is an anti-aliasing filter needed somewhere? :wink: -

Our Great Photo Processing Shootout!
I can't quite remember whether or not I had a filter attached to the lens when taking the shot in this thread. It is possible that I may have had a 0.3 ND Grad, but I certainly didn't have a UV or polarising filter attached. For most of that morning I had no filter at all, as the majority of shots...

Product Registration
I only register something if there is a good reason to do so. I registered my Sigma lenses as you get an extra 2 years warranty, my coffee maker because I got a free water filter and the new microwave oven as we got a cookey book and Le Creuset casserole dish. Pentax gave me no reason to :wink:

Billingham Hadley Large/Pro
Had the dividers today and (almost) filled the bag up. I know John has often recommended the Hadley Pro/Large, but I'm amazed how much kit can fit into such a small seeming bag. Just thought it might be useful for anyone else considering one of these what I would manage to get in, comfortably. ...

K-r @ Macro
There is another much simpler option that has not yet been mentioned in depth and should be considered. That is buying a macro conversion lens such as the excellent Raynox DCR 250 Macro scan conversion lens. These just clip on to the front of your existing lens (filter thread needs to be betwe...

The Meaning Of Moire
Its great fun Andrew! All the other Pentax DSLRs (and indeed most others) have what is called an anti-aliasing (AA) filter in front of the sensor. The K5IIs doesn't. The AA filter removes interfence patterns such as AndrewK's link shows. So if there is a fine repeating pattern that you are trying...

Reverse Nd Grads
And here was me thinking to myself 'why don't people just turn the filter the other way round? :mrgreen:
