DedupeQuick Reference Guide to Control Depth-Of-Field
Last Updated :Depth of field is controlled by three main factors i.e. aperture, lens focal length and the shooting distance. Your aperture & lens focal length depends on the shooting distance. So, we can say that selecting or choosing a right aperture setting & focal length can guarantee that the dephth-of-field in your photos is absolutely appropriate.
Here's a quick reference guide to understand the relation between aperture, focal length and the shooting distance.
- Smaller aperture = deeper depth of field (the other two factors remaining the same i.e. focal length & shooting distance). For e.g. Keeping focal length and shooting distance the same, you'll see a much deeper depth of field at f/16 than at f/1.4 aperture.
- Shorter focal length = deeper depth of field (the other two factors remaining the same i.e the aperture & shooting distance). For e.g., If you compare a 28mm lens with a 50mm lens at same aperture & shooting distance, You'll find that depth of field is deeper with the 28mm lens as compared to 50 mm lens.
- Greater shooting distance = deeper depth of field (keeping the other two factors i.e.focal length & aperture same). For e.g, if the subject is photographed from different distance each time, the zone of sharpness in the foreground and background is greater when shot from a greater distance as compared to when shot from a small distance.

PicBackMan does exactly what it's supposed to. It's quick and efficient. It runs unobtrusively in the background and has done an excellent job of uploading more than 300GB of photos to 2 different services. After having lost a lot of personal memories to a hard drive crash, it's nice to know that my photos are safe in 2 different places.

LOVE this program! Works better than ANY other program out there that I have found to upload thousands of pictures WITH SUB-FOLDERS to SmugMug!
Thank you so much for what you do! :) #happycustomer

I pointed PicBackMan at a directory structure, and next time I looked - all the photos had uploaded! Pretty cool. I use SmugMug and while I really like it, the process of creating directories in is pretty laborious when you need to make 80+ at a time. This was a breeze. Thank you!

PicBackMan was really easy to setup and has been running for 3 days now backing up all my locally saved photos to Flickr. My photos are really valuable to me so it's great to be able to have them easily backed up to a secure location.
Jim Griffin It's AWESOME!! I have tens of thousands of pictures...and they are now successfully uploaded to SmugMug, where they are safely backed up, and I can edit and organize them. If you are hesitating about using PicBackMan, hesitate no longer...try it...and you'll be glad you did!!

I started with the basic plan, went to premium and now on their platinum plan and it's more than worth the price for me. PicBackMan has saved me many tedious hours of effort moving many files between my various cloud and photo site services and my local computers.

I am very satisfied and surprised at the same time with Pic BackMan. The service is very good and useful. I used it to transfer my photos from Dropbox to my Flickr accound. I highly recomment it.

PicBackMan was an answer to many a prayer. How can I get this MASSIVE collection of photos onto a service that cripples uploading? PicBackMan. I uploaded approximately 85,000 photos in less than a month. It would have taken me close to a year to get all of those photos where they needed to go. Nothing short of brilliant.
Dary MerckensI have thousands of family photos and it's always been such a pain to upload them to various cloud services for offline storage. Well not anymore! PicBackMan makes backing everything up a complete breeze. I don't know how I ever lived without it!
Glen MartineauI was poking around the Internet looking for an easy tool to help me consolidate 15 years of my pictures from Google Photos and Flickr etc - this tool was very easy to use and was painless to setup.
