The 100 x 100mm ProGlass IRND 4.5 Filter from LEE Filters is an ND filter with a 32,000x filter factor that provides a 15-stop exposure reduction. Its 4.5 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you can control depth of field and convey movement more easily. Neutral density filters are intended to not affect the coloration of the image and are ideal for pairing with other filters.

The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible 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 100 x 100mm ProGlass IRND 4.5 Filter is constructed from scratch-resistant, optical glass for clarity as well as color fidelity and features a built-in gasket. This gasket works with a compatible LEE Filters 100mm System filter holder to help form a seal that is intended to prevent stray light, which could have unwanted effects on exposure, from coming in between the filter and the lens behind it. For efficient use in the field, an exposure guide is included that shows the amount of exposure reduction the 100 x 100mm ProGlass IRND 4.5 Filter provides, corresponding to a range of shutter speed settings from 1/1,000th of a second to 2 seconds before the filter is applied.

  • Compatible with a LEE Filters 100mm System filter holder.
  • 100 x 100mm neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
  • Providing a 15-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.
  • Filter does not affect coloration of the image and is appropriate for use with other filters.
  • Attenuates infrared light as well as visible wavelengths, to maintain color neutrality and suppress color casts due to increased exposure times.
  • Constructed from optical glass for clarity.
  • When combined with a LEE Filters 100mm System filter holder, built-in gasket helps to prevent light from coming in between the filter and the lens behind it, which can have an unwanted effect on exposure.
  • Exposure guide for efficient use in the field.
  • Padded pouch included for storage and transport.

Very detailed! Beautiful world building! Strong Heroine!
Format: Kindle
Starts off a little slow and confusing with different POV’s, but starts to all come together towards the middle to make an elaborate plot line and makes it all worth it. Beautiful world building and attention to detail as well as great writing. The cliffhanger was gut wrenching! Can’t wait for the next book!

Interesting
Format: Kindle
This was a very captivating book once you got into it thoroughly. But the third person perspective was a bit hard to get used to. But as you got into it and followed the different characters, it was interesting and filled with intrigue, conflict and forbidden love. I can’t wait to read the next one and to complete the series.

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.
