The Tiffen 4 x 5" Round 85 Ultra Pol Linear Polarizer Filter combines both an 85 color conversion filter with a linear polarizing filter to blend the effects of both filter types into a single, convenient solution.

The 85 color conversion aspect of the filter provides a warming effect and decreases the color temperature from 5500K to 3400K, allowing the use of tungsten balanced film in daylight conditions.

The Ultra Pol linear polarizing aspect of the filter helps to greatly reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A linear polarizer differs from a circular polarizer in that it does not supports use of a camera's autofocus or auto exposure functions; it is best suited for use with manual cameras, such as view cameras, that are not dependent on internal mechanisms to determine focus or metering settings.

There is a total filter factor of about 6x, requiring an increase of 2.6 stops for normal exposure. Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 5" / 101.6 x 127mm.

Ultra Pol linear polarizer and 85 amber color conversion filter combination.
Total filter factor of approximately 6x requires 2.6 stops of additional exposure for normal results.
Warming 85 color conversion filter decreases color temperature from 5500K to 3400K for using tungsten-balanced film in daylight conditions.
Polarizer helps to greatly reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
Clears up haze in distant landscapes and provides more saturated, vivid colors.

Compared to a standard polarizer, the Ultra Pol design strives to increase the polarizing effect for enhanced reduction of reflections and greater color saturation.

Great for mental stimulation. Durable for my chewers!
Color: Purple Lil Snoop, Color: Purple Lil Snoop
Love these! Quality material, safe for dogs — I make my dogs home made freezer treats and fill these up with it, and serve. Keeps them busy for hours. It’s also fun for them to roll it around to get regular treats out of. Toy + treats = a very happy pup. This size I got for my puppy. The larger ones I use for my adult dogs. Super cute too, and silent! I have Mini Aussies, so it’s great mental stimulation for them. Tires them out.

No challenge once they figure it out once, or if they have a long nose
Color: Blue
The first time I used this with my 9 month old Shepard mix, it was great. We used about 1/3 cup of her kibble and added the Nook to make it harder. It kept her working for 20-30 minutes. However, now that she knows how to remove the Nook, and stick her snout into the opening and lick up the kibble, it lasts about 5 minutes, and is no longer a challenge. She still enjoys playing with this, even when it is empty, and hasn't it destroyed it yet, so for that 3 stars.

Awesome toy, add peanut butter
Color: Blue, Color: Blue
I love this, and so does my dog! Yes, plain kibble can fall out too easily, so I put a blob of peanut butter in too and that helps it stick better. Bigger treats work great, as well. Its big and slippery enough that she can't rip it apart, which is great. Absolutely recommend, it's cute to see my dog flip and nose this around. I will probably getting the purple one too, as they are quite affordable. A+

Bento Ball for the Win!
Size: Large
I got the Starmark Everlasting Bento Ball for my doodle, and it’s quickly become one of their favorite toys. First off, it’s super durable—which is a must for doodles that love to chew. This ball is made from tough material designed for aggressive chewers, and it actually holds up really well over time. What I love most is the mental stimulation. You can fill it with treats or kibble and even add a harder “cap” treat on top, so your dog has to work for it. It keeps my doodle busy and entertained way longer than a regular toy. The erratic rolling design is another win—it doesn’t just roll straight, so it keeps your dog engaged and curious. Bonus: the textured surface helps with light dental cleaning while they chew. 🦷 👍 Pros:    •   Extremely durable (great for doodles/chewers)    •   Keeps dogs mentally engaged    •   Doubles as a slow feeder    •   Easy to clean (top-rack dishwasher safe)

Very Durable and keeps dog busy
Size: Medium
We have a dog who loves to chew up EVERYTHING!! She is constantly getting into things and if she can't reach an item of interest, she will find a way to get it, even if it means jumping up on the counter or pool table. LOL. We've tried every puzzle toy and treat you can imagine to keep her busy and tire her out mentally, but nothing really worked that well. She would figure the puzzles out quickly and become board with them after several uses, and preferred to try and chew up the plastic instead. Treats, like bully sticks, that should last a "long time" were gone within 10 minutes. I didn't have high hopes for this product given the history of our dog, but I WAS WRONG!!! The treat was already in the ball when it arrived, so I gave it to her like that. She licked, pawed, and chewed at this treat for hours and did not get board with it. She wore down a little of the dome shape on the treat by the end of the night, but there was still a lot left when I took it up. I gave it to her again the next evening and again it kept her busy. By the third day, the treat was worn down to a ring shape so I took the treat out of the ball and gave it to her. She ate it in about 3 minutes. After examining the ball, it is still in good shape with no damage like we found with hard plastic toys like the kong wobbler. We will definitely be ordering the refills to use with this ball. Best product we have found for busy, destructive dogs who become board easily.
