Initial Announcement

Hesper Photo Mosaic Practice Project
August 10 - 11, 2013

This project is a very unique and special project the GLSPS put together.  You really shouldn't miss this one!  Learn from the experts on how to use drop cameras to shoot videos on deep shipwrecks to deep to dive.  If you ever wanted to get started with the basics of shooting video to document a shipwreck underwater with out getting into the water, this would be a great project to participate in.

If you are a shipwreck hunter or want to be a shipwreck hunter, this method is used to document a shipwreck after it is discovered.

You will also learn this procedure from the very famous shipwreck hunter in the great lakes, Jerry Eliason.  Jerry has many Lake Superior shipwreck discoveries accredited to his name, including the most recent discovery of the Henry B Smith in Marquett Michigan.

If you are interested in learning more about this project and would like to contact either the Captain of the RV Preservation and Leader of the Project, please use the information below.  Or, you can click on this link to bring you directly to the Project description. 

If still interested please click on the "Register Now" button and register ASAP.

We hope to see some interest in the membership of the GLSPS in learning to shoot underwater video to produce a photo mosaic.  If you always wanted to learn this technique, please register ASAP before you miss out.  This project may not ever be offered again by the GLSPS.

Please Note:  There may not be any diving associated with this project.  For more details please contact Bob Nelson.  His contact information is below.

Hesper Photo Mosaic Project 2013
August 10 -11

Closing Report

The Hesper Photo Mosaic Project was set up by the famous shipwreck hunter Jerry Eliason.  He had a need to practice shooting video with his drop camera on a shallow shipwreck to gain experience in learning more about creating photo mosaics on deeper shipwrecks he finds and that can't be dived because of the great depths in which they are lying in. (Such as 400 feet plus). 

Jerry has created a preliminary photo Mosaic of the Hesper in Silver Bay.  The shipwreck is fairly shallow so he had to use a wider angle lens to shoot the video to create the Photo Mosaic.  Jerry discovered that the wider angle lens doesn't function like he would like for it to.  The wider angle images that the wider angle lens creates distorts the images to much and presents a quilt type pattern of the HD photo.  Here is a preliminary photo mosaic of the Hesper.

Jerry is going through another process to cleanup the distorted images.  As soon as the photo mosaic is finished, we will display it here in the closing report and the photo page album of the GLSPS website.  Or, Jerry will have another Hesper Documentation Project to create another photo mosaic.

However, he has learned a lot by performing this action on an easier shipwreck to help him implement another Photo Mosaic Project on the Benjamin Nobel shipwreck next year, which is lying in 360 feet of water.  This shipwreck has been dived before but at this depth, it become very risky and can only be down there for a very short period of time.  This would make the photo mosaic a very long project.  This is why Jerry thought it would be more efficient to have his special designed drop camera to do the dirty work for him.

Thank you to those that help on this project to learn how we can efficiently create photo mosaics to document deep shipwrecks.  This is what is needed to place the newly found shipwrecks on to the Nation Register of Historical Places.
