Divers from the submarine cruiser Thomas Winans begin an excursion to explore a wreck. The submarine, which I've named for Thomas Winans, one of the Winans family who had much to do with the development of the cigar ships in the mid 19th century, is Ig Yerm's imaginatively realized Future Winans Steam Ship, available at ArtStation and other sites. The divers are M4 in Cybertenko's Deep Sea Diver suit. The wreck is IN Wavecutter. The sea life consists of sharks from Shark Attack, Sea Turtle and Tuna from DAZ, and several old freebie fish. The environment is Nemo's Hunting Ground. The scene was composed and rendered in Poser using Atmosphere for the depth effect.
