The Formatt-Hitech 13mm Firecrest ND 3.9 Filter is a solid neutral density filter providing a 13 stop reduction in exposure. This 3.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or longer shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.

The design of this filter has been optimized for use with digital sensors and promote nearly flat attenuation of visible, UV, and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times. This filter provides a high level of neutrality across all three spectrums in order to eliminate color casts and ensure cleaner, truer blacks.

Applied to the outside of the Schott Superwite glass construction is a 15-layer Firecrest multi-coating, which helps to minimize reflections and flare in order maintain truer colors and contrast. The multi-coating is also scratch-resistant and hydrophobic to benefit the overall durability of the filter. It measures 6.5 x 6.5" / 165 x 165mm and is 0.08" / 2mm-thick, making it compatible with the Lucroit 165mm Filter Holder.

ND 3.9 filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
Providing a 13 stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.
Attenuates infrared light, as well as visible and UV wavelengths, to maintain color neutrality and suppress color casts due to increased exposure lengths.
The 15-layer Firecrest coating has been applied directly to the outside of the filter glass by way of a vacuum-formed, hard-coated, electrolytic process. The multi-coating is water- and scratch-resistance for greater overall durability.
Schott Superwite glass promotes maintained image clarity and its 2mm-thick design is compatible with the Lucroit 165mm Filter Holder.

This is the best nursing bag I've purchased so far
Color: C02- Generic Sunflower, Size: Large
I am one of those nurses that "lives" at work so I bring everything that I might possibly need in a twelve hour shift - including my planners, pens, medications, drinks, and toiletries on top of my usual nursing items. I am usually stumbling into work with multiple bags but this one solved that problem. I got the large bag. I looked at it at first and said, "nah, it's not going to be big enough" but as I opened it and started putting my items inside, I couldn't believe how much it holds. It's good quality and the design is beautiful and not blurry or "fake" looking. There are 6 outside pockets and multiple inside pockets for organization. I prefer the handles over the shoulder strap because it's pretty heavy when I load it up but so fst, seems to be good quality and holds up to my needs. It's not a bad price, either. It's comfortable and well made. I will have to come back and post a picture/video during the day.

Color: A20- Dental, Size: Large, Color: A20- Dental, Size: Large
This is way bigger than what I thought! I would've gotten a medium just cause I'm not sure it'll fit in my locker but I’ll still use it lol! I absolutely L❤️VE this bag and it is so cuteeee! Im a dental assistant so I got the bag with teeth ✨🦷 I have been carrying a dollar general tote bag for work to carry all my stuff. So this is a major upgrade for my work bag! It’s so spacious with lots of pockets. The material feels thick and durable also. Has purse straps and a shoulder strap so you can carry it different ways.

Overstuffer Approved
Color: B23- Nurse Black With Leopard Embroidery, Size: Medium
I love this bag. At first I didn’t think it would work for me because of the size and feel of the material but it’s actually pretty sturdy. The outside pockets hold my cell phone, beats earphone case, charger, and car keys perfectly. I carry my stethoscope, thermometer, O2 spot checker, etc, notebook, book, my purse, lotion, and wallet inside. The water bottle pocket on the side is deep and snug enough to fit a ninja travel cup. I bought the smaller size and as an overstuffer, it’s spacious & the zipper is flexible so it covers items that may stick out from the top a little. Great bag for nurses!

Very spacious
Color: A29- Nurse Tool, Size: Large
I was looking for a spacious bag to carry all of my school supplies and this one is perfect. It’s able to fit both of my large school books, a 5 subject notebook, multiple pocket folder, notecards box, pencil case and my laptop in an interior padded compartment. The padding is a little thin but none the less I didn’t realize it came with one so that was a bonus. It has 3 pockets inside & 3 deep pocket outside on each side of the bag plus the 2 mesh pockets. As you can see the mesh pocket fits my 40 oz tumbler. With all of my items this bag weighs 24lbs and so far so good the straps feel pretty sturdy/durable.
