Hi all, When comparing the options for my octobox purchase I noticed some use a mount that faces the flash inward toward the reflective surface while others use a speedring where naturally the flash faces forward from the rear. My concern is that with the flash facing inward the flash and mounting bracket may block at least a portion of the reflected light especially when there is more than one flash mounted facing into the dome. Any reason to purchase one over the other? Just a thought. Thanks!
