In case anyone is not aware of the aspects that determines the intensity of the sharpness of parts of a photo (usually the backdrop), here are 4 things we need to take note of.The size of the apertureAperture opening size determines the depth of field of a photo. It is a common saying and most beginners even know that a fast lens with the biggest aperture you can get is desired for portrait work and throws the background out of focus so that attention is locked and given to the subject.... continue reading

What I think about the difference of Sigma Sigma 50mm and 105mm macro lenses is that with Sigma EX 105 / 2,8 DG OS HSM Macro avoids the insects fly away when you do not have to go so close to the object. After that you get a little more Dof dots out of focus when shooting with a higher focal value. continue reading
Recently I discovered some really great apps that can help you improve photography. If you know more such apps please share them in comments.In order not to name only a few or just the ones that I use, I’ll try to group these apps into categories so you can search for more or better apps that do similar things.App showing moon phase and stargazing conditions - for those photographing at night this type of app will be great. You either want to know if you’ll have a clear sky where milky... continue reading
They say Kit lens is the beginner's lens. True it is. But I started my DSLR photography with a 50mm prime and since then I am madly in love with my magic lens! In fact I still do not own any kit lens! :DYou can do thousands of experiments with this much lighter weapon!The focal length is almost close to the perception of human eye. It covers the whole zone as your eye can see at once. Makes the picture more real. I never forget this tiny wonder when I go for street photography. Just apt for... continue reading
With eyes at or close to the same distance from camera to achieve equal focus on subjects.This gives each person equal importance to the image.Works well for families.Allow one to be in focus and the others to be out of focus.Combined with the composition of your photo, using diagonals or rule of thirds, etc, you allow the one to become the primary focus while the others fade into the background.So, there are my thoughts.Most of these images are not mine, but I thought... continue reading
Sometimes, especially in macro world, we want to take a picture of something so that the background is soft or blurry but the main subject is completely in focus. Then we use wide apertures to get that effect. But with wide aperture, the depth of field becomes very shallow and not all the main subject may remain in focus. I've read many articles from the internet and found a solution - Focus Stacking.Focus stacking means that we take multiple shots of the subject so that the focus point on each... continue reading
One of my latest images just sold, and it occured to me that I have very few images with shallow depth of field as a key feature.In some closeups it is enevitable, but I rarely use it as a 'focus' of my stock images.There are a few reasons for this:1. Lens are a little less than optimal at wide apertures, leading to potential rejections.Macro lenses (such as used in my cookie shot) are exceptions, but most fast lenses will introduce color fringing in out of focus areas.2. Maximum flexibility,... continue reading
According to this vidéo, it look like that Adobe found the solution to correct the blur picture. It will outdate all IS/VR expensive lens.http://www.youtube.com/watch?v=xxjiQoTp864&feature=player_embedded#%21Impressive demonstration. continue reading
When I started with photography a year ago, wide aperture lens ( f 2.8, f1.4) were all that I desired as I wanted to shoot in low light situations and also get the pleasing bokeh in almost all my shots by using the widest aperture. I enjoyed it very much.Then I joined dreamstime and these images with my aperture wide open were rejected as the depth of field (DOF) was too shallow and much of the images were out of focus. Thus I started to shoot with smaller apertures to get that DOF. Moreover the... continue reading
Remember, if you shoot with a crop sensor camera you have more DOF than a full frame camera if you were to attempt framing the same shot with both types of cameras... Take the same 50mm f/1.4 lens and put it on a Full Frame D700 and then put it on a Crop D300.Assume you are shooting at f/1.4.Because of the crop factor on the D300, you need to step further back from your subject which gives you more depth of field.The same composition on the D700 will yield a background that is blurrier than... continue reading
