Re: Fun with the Sony A7 and A7r series
Happy Easter Everyone
Wanted to add a few more food shots . These again where with the Sigma 35mm 1.4 Art lens. Both images around F9 and both with 4 focused stack shots. On the A7r tethered via C1 with hot folder I can shoot and see immediate effects but more important and the biggest reason I bought the Sonys was focus peaking. In this situation its the best there is as I can see where my focus points are take that frame than focus out 2 or 3 more times until I get in this case to the end of the food and build a nice very detailed image from the front of the product to the end of the product. Want to make this clear yes I am adding DOF but more important I am adding critical focus points along the way so in effect it is DOF but it really is not but expanding the critical focus from the front to back. DOF would not be this critically sharp. This is a very important and valuable technique in many situations. Here its so easy to do this as I am bolted completely down and nothing is moving in the image. This is IMHO a little better than having Tilt as you can see the effect a little easier and be a little faster in the process. Now love to have a tilt lens but this is a extremely good cheat to accomplish that depth of critical focus. So this is your Easter Tip of the day. I use Helicon Focus to do the blending. BTW I also corrected in C1 the keystoning than applied that setting to all of the same focus stack images before using Helicon to blend
Take a look at there website for more data on this. I was going to do a front page article on this technique but did the camera instead. IMHO this process could not be more financially sound as all your buying is software. So if you don't have a T/S lens this is a excellent way around it.

Turkey Pot Pie
Ribeye Steak. Hmmm good too
I used here the wine storage area as my backdrop
