Help with getting perfect white background with shadow.





Hello!

I am doing some product shots for a company.

I tried to get the closest to white as possible background when shooting, but it is still just a bit off.

I am not sure how to easily correct the background to perfect white. 

Any help would be great.

Here is one of the photos I am trying to correct.

It is close to white, but needs to be perfected. How can I change it?

Thanks.

Pardon me, but I think you're all overcomplicating this Just use the white eydropper on the background. Done. Here I dragged out a white background just to demonstrate. Yes, you can barely see it in the top left corner, but that's easily fixed:The problem with complicated masking in these cases is that it so easily gets inconsistent and looking fake. What if the white in the reflector is light gray while the background is white?People reach for masks and selections far too quickly IMO. Half the ...
basically, you could use picking from the camera to the center of the tag position to see if it is behind something.

if yes, you could manually adapt the style. After 5 hours of learning I have compiled these:


Mindset



1. **Make sure the placed image ratio is good** to make it more realistic. This can be attained by checking with the other object in the output picture, like trees, or other peoples' height. You are not going to place human with the size much smaller than the other human at the same picture. Similarly, you also must not place a person with the height higher than a tree.
2. **Get the right perspective**. Sometimes, when an object is placed in an odd perspective, image is going to look very bold that it has been photoshopped or copy pasted.
3. **Lighting**. It is important to pay attention to light source, like the sun, and make sure our object is appropriate with output background light source. This can be done by adjusting the lighting of object and adding shadow with referencing other shadow in output image.


Tools (to make edges more realistic)



1. **Layer masking.** If moving people, hair can look awful if just plainly moved. Masking allows us to further tweak our selection.
2. **Refine edge.** *This tool allows you to control many aspect of the edge of your selection* (desired object to move), like Edge Detection (brushing the edges of object and let photoshop do its job, usually around dog fur), Feather (Soften the area of selection), Smooth (reduce pointiness of your selection), Contrast (somewhat opposite of smooth), and Shift Edge (moving feather far or nearer the selection, usually to remove excess background color near the edges). *REFERENCE: <https://www.youtube.com/watch?v=5lDr2Nd8Yl4>*
3. **Layer Matting**. Inside we have many sub-tools to work on, like Color Decontamination (spread out soft mask around the edge, usually for hair to catch other hair that accidentally masked or can be used similarly to Shift Edge), Remove Matte (soften edge of sharp graphic or pixalated, raster look). *REFERENCE: <https://www.youtube.com/watch?v=N6K_htNQPPA>*
4. **Image Calculation**. By playing with the blending, we can make the background darker; thus, helping us making mask. *REFERENCE: <https://www.youtube.com/watch?v=0zf-H9RoCNk>* on some cameras, there is a setting in the menu screen to adjust the brighness of the screen. i would also suggest just using the viewfinder to take pictures as well. here is a good system, camera plus lens: http://www.bhphotovideo.com/c/product/767600-reg/nikon\_d3100\_digital\_slr\_camera.html

please be aware that in some cases prices for cameras are prices for body only; the lens is extra.

and, stay away from the 'grey market' products. Photography is the process of making pictures (graph) using light (photo)...  
Light takes the most important role on produce nice pictures  
  
There`re no fixed rules about photography, it`s an art so nobody have rights to say that the photo is good or bad...  
  
During rainy day, you should prepare camera`s water-proof jacket or an umbrella to protect it against water. Some expensive cameras have been equipped with water-proof material. hey thibaut,

i believe what you want to try is adding is a rectangle object that fills the rest of the screen but is a 0% opacity background. this may help to keep the object from resizing for the screen. ![](https://s3mn%20mnimgs%20com/img/shared/discuss_editlive/2191102/2012_01_06_16_34_59/high%20bird%20png)
conditions for the formations of shadows are
1 a light source, an opaque obstacle, a screen
2 umbra, that is the dark part (shown in the above figure by the
dark triangular shape) of the shadow must fall on the screen @derek higgs interesting, mine lights up the kitchen like daylight normally! thanks for this, if you go into settings, there’s a setting called backlight which has options on or 1 min; i cahnged mine to 1 min, just nipped downstairs (at 12:02 am) and the kitchen is in darkness! i’m unsure when it went off but if you change the backlight to “on” it will light up all night. peter switch off the extension for dark mode, it is changing things

there is a native dark mode you can switch on in the settings hi [@samliew](/u/samliew)

thank you for your feedback too. i’m overwhelmed by all the support.

it seems as though this is something i can fix myself, without too much technical knowledge. i’ll get onto it today.

thank you again!
