- (Water Filter) Many coffee and espresso machines feature a built in water filtration system. Some are very rudimentary, consisting of a mesh or metal filter which water must flow through before reaching the boiler or heating element.
- (Water Filter) In higher end espresso machines, a mechanical or a charcoal filter is integrated to remove unwanted components from tap water before the brewing takes place.

New Pro Stop from Hitech vs. Bigstopper from Lee

Testing the new filter Formatt Hitech PRO Stop (10 stops)
About the filter:
The Format had a 10 stops filter since a few years ago but unfortunately had serious problems with a strong magenta cast due to high sensitivity to infrared rays becoming complicated revolving this effect in post-production
The company announced two weeks ago its new ND 10 stops filter named Pro Stop, being a clear race to compete with the devoted Big Stopper from Lee that was released just over a year ago. It was produced a new CR39 resin which has a higher resistance to infrared rays, all the raw material, research and manufacture is from the Formatt factory, contrary to Lee's model in which the glass substrate comes from outside of Europe causing high time delays and no sufficient quantities for international orders.
The content and options:
The filter is supplied with a nylon protective bag and incorporates a sponge in its periphery (such as the Lee filter) to prevent the entry of light in the filter support / lens avoiding flares and unwanted reflections and is sold on a variety of choice in the following versions:
- Size 85mm (so far the owners of the system Cokin / Hitech of this size were prevented from coming to buy a filter with the characteristics of the Lee Bigstopper as it only exists in the system 100mm)
- Size 100mm with two variations:
3mm sponge for the Hitech filter support
1.5 mm sponge for the Lee filter support
The assumptions for the comparison:
This comparative test was performed on the same day and the photos are outdated in a few minutes using a Nikon D7000 with a Sigma 10-20mm lens on a Lee 100mm filter support.
The high-density filter was placed in the first slot of the bracket and with the sponge facing the lens side (of course!) because only this way you are guaranteed that no light enters into the lens.
Was added in the following slot a gradient filter 0.9 (3 stops) from Hitech aligned on the horizon and kept in the same position in both pictures to balance the light between the two halves of the image.
Just changed the exposure time while maintaining the same value of ISO200 and f/7.1 so that the quality of the pictures were identical as possible.
It was found however that there is a density difference between the tow filters of about 1 stop, where the Bigstopper filter has more than 10 stops , and the Pro Stop filter has less than 10 stops, as a result, the exposure time for the Pro Stop was 30 sec. and the exposure time with Bigstopper was 1 minute.
The WB in both pictures was in Auto and both pictures were shot in RAW format.
For a correct WB between the two photos was chosen the same reference point in both photos, located in the cement wall on the horizon in to the right side of the picture using the Nikon Capture NX software. As you will see, the strong magenta cast problem no longer exists in the Hitech Filter which in itself is good news, though, in both comparisons, there are some observations to make:
In Pro Stop, both sky and water tend to the same tone despite the half above the horizon have a gradient filter placed. The brown color in the rock tend to have a slightly reddish tone.
In the image of Bigstopper there is a separation of colors between the sky and water which may be the result of a reaction from the gradient filter placed in the top half (ND grad Bigstoper resin versus glass?), The colors in the rock tend to yellow / golden.
While the image with the Pro Stop, when increasing the color temperature, tends to gray tones in the sky and brown in the water, and the rock tends to a shade less red and more yellow, as in the Bigstopper image the sky turns slightly purple and the rock is replaced by a yellow tone and too unrealistic.
Resolution / quality:
I did not observe differences in definition and contrast between the two filters, at least using the Sigma 10-20mm lens.
Pros and Cons:
- Increased durability as being made of resin is not as fragile / breakable as Bigstopper
- Availability of replacement of stocks in a shorter period than the Lee filter
- Lower price
- Possibly more compatible with the Hitech filters gradients (requires further comparative tests with Lee gradients to consolidate the fact)
- Scratches more easily than the Bigstopper glass.
Experienced users of this type of filters know that each model / manufacturer has its particular characteristics, the circular filter B & W tends to reddish-brown, the Bigstopper from Lee tends to be bluish and Pro Stop Hitech is a mixture between these two characteristics and therefore also not free of features, such as other ones.
For users of the 85mm support system is an advantage because they can enjoy a magenta cast free long exposures filter and the light input problem resolved at a price much lower than the Lee filter and no need to get rid of the current 85mm system
I developed my first roll, and it's in color : )
Developing C41 at home was not as difficult as the rumors said : ) Today, I received the Tetenal C41 kit from Photax.se and developed my first roll. The most difficult part was to control the temperature of the chemicals to be exactly 38 degree Celsius. There were many methods to do it online. I was even thinking about buying a temperature controlled heater, which is by the way not cheap at all. But I figured out a simple way that's very effective. I kept the water running out of the tap to be around 38, and filled the water in a small tank. I kept the water running even if the tank was fully filled, so that new water kept coming and it pushed the old water out. This method was extremely effective and the water in the tank kept to be 38 all the time!
I developed three rolls in total today. Now I need to scan them, one by one : )
