Calculate Min Max For Stock Items

Works as described and I love the little Max and Min notches on the side of the filter to help me get exactly how much effect that I want.

Very easy to use. Dont pass min and max mark and it will be fine.

Good ND for all around uses as long as you are aware with the line between the max and min, there's like half clear half dark exposure (separation between the two).. minimm or no color cast, good contrast..

I used the Tiffen Variable Neutral Density Filter for a few weeks now, and so far it's been working great for me - no spots or darker areas. You just need to make sure you don't turn it beyond the max/min positions (it doesn't have stops on either end, so it is possible to rotate it way beyond max or min). I have not noticed any chromatic distortion or aberration either. Very good and solidly built filter.

Unlike others I have used, this one locks at the min and max strength and is relatively small in size. Overall, a great high quality product.

[This review was collected as part of a promotion.] So first, this drive is geared toward portability and not top-end performance as most would want these days. When I say portability that goes toward travel not only in the states but around the world. It comes with 6 power adapter-style plugs so you can change out depending on where you are in the world. Not only that but it also serves as a quick USB hub so you can use different peripherals through the USB 3.0 connection the drive uses on your system. It does have flashy RGB LEDs and you can change the colors or patterns on through the software downloaded to manage the drive. The software allows you to backup, restore, or mirror your data files. If you have Razer Chroma then you can also link up your RGBs with that as well using the toolkit software. I did do a performance test to see what the real world specs were compared to seeing what was online and here are the ones I ran: IOPS 4K Read Min: 1.04 MB/Sec. Average: 7.02 MB/Sec. Max: 7.85 MB/Sec. IOPS 4K Write Min: 0.00 MB/Sec. Average: 0.76 MB/Sec. Max: 5.97 MB/Sec. IOPS 4KQD32 Read Min: 0.93 MB/Sec. Average: 26.96 MB/Sec. Max: 36.09 MB/Sec. IOPS 4KQD32 Write Min: 0.00 MB/Sec. Average: 1.30 MB/Sec. Max: 9.10 MB/Sec. IOPS 512K Write Min: 0.00 MB/Sec. Average: 36.44 MB/Sec. 1Max: 30.8 MB/Sec. My opinion but if you are a traveling gamer/media watcher/need storage on the go while going around the world or even in your own country then this is a great external hard drive for you. Easy to setup and easy to pack away.

I purchased one of these to add to my gear and what an amazing stand. Max height 14', min 64 and it can hold 88 lbs. The wheels are super smooth and the wheel lock works perfect. It's a triple riser and when extended it is a sight. I was looking for a stand to hold a heavy light and with will do the job and then some.

Between the min and max marking, you get about 5 1/3 stops of densitiy variation with hardly any change in color. I've read some reviews here where people complain about the Big X across the picture that is caused by this filter. Well that's what happens when you turn it beyond the maximum density marking. Don't do that, and you'll be happy.

Like all ND filters this one has a little color shift, but it’s nothing crazy. The markings on the filter are not calibrated stops and are just there for reference. Things to improve this filter would be stops at the min and max versus having it spin 360 degrees, but I’m not aware of any filters that do this. If you use this filter outside of its min and max tolerances, you will see undesirable results with crosshatching in your images, etc. ive tried more expensive ones and it wasn’t worth the price. Unfortunately, I haven’t found any budget ones that could keep up.

This is probably the best tank in the market that takes a small amount of chemicals (450ml min/475ml max) and can be manual agitated via inversions. It's significant because what's available out there either requires a lot of chemicals or it's for a rotary process. I have a Jobo 2520. It's tiresome to manually rotate the tank and those machines are incredibly expensive. On the other hand, this is a better investment. It can handle C41, E6, and black and white. It's very important to follow the note on the tank that says to squeeze the tank to take out the air or else you'll have a leaky experience. It's very easy to load and keeps the film flat. I've read that the holders leave development marks but I havent experienced them. This is a must buy for 4x5 photographers.
