Vernon Chalmers Photography now using WhatsApp Business

Important Update: Vernon Chalmers Photography Support / Communications now also available via WhatsApp.

From this week I will be using WhatsApp Business for complimenting my current client support, pre-training and booking information.

The WhatsApp Business number for messaging / phone calls - direct link: wa.me/27608878087 or 060 887 8087

Due to training commitments I may not always respond immediately, but there will be an auto-responder message if this is the case.

Please note: This number is for photography training / support purposes only. Please do not add / invite Vernon Chalmers Photography to any WhatsApp group functionalities et al.

I trust this new communication channel will be of substantial assistance to current clients with Canon EOS / photography support requests and possible new clients with pre-training / specific learning information requests.

Birds in Flight Photography: Background Blur Considerations

Background Blur Considerations

Slower aperture lens on APS-C / Crop vs f/2.8 lens on Full Frame body

With a fast aperture lens, i.e. the Canon EF 300mm f/2.8L IS II USM super telephoto lens, its much easier to blur the background - and when paired with a full frame body its almost effortless (ito panning and the work required for rendering background blur compared to an APS-C / Crop sensor body and / or slower aperture lens).

The end result (ito background blur) may look very similar, but there was much more tracking, pre-focus and panning involved with the 1st image.

Distance between foreground and background / depth of field for both images are very similar - and captured in the same area in the Milnerton Lagoon, Woodbridge Island, Cape Town.

Due to the the larger sensor of the full frame body I was able to crop the 2nd image to more / less the same dimensions as the 1st image.
