Update: for another perspective on this debate – check out Why I DO HDR – A Fresh Take on a Tired Debate. There is so much great stuff to learn about proper exposure that the HDR gadget can just sit at the back of the drawer like the outgrown toy it has become.Ĭare to differ? Please do! Just keep it civil. Just stop taking it too far and stop using it in place of proper exposure and accepting the limits of the scene in front of you. I know it’s a bit of a craze and newfangled thing right now. It’s not that HDR is totally evil (just mostly) and should be done away with. But the majority of people trying out HDR, and taking it too far, are people who should be experimenting with shutter speed and depth of field first! Yes, there are some photographers, much accomplished in the field, who experiment with HDR. I see it used more as a gimmick than an honest extension of one’s artistic vision.
EASYHDR WRONG IMAGE DIMENSIONS FULL
It bugs me that, when I look at the full gallery of someone with an HDR shot, on Flickr for instance, people getting into it still don’t have the fundamental basics down to the point where they can produce solid photos time and time again. All of them do, so why shouldn’t HDR?īecause there is so much more to learn and improve in the realm of photography that HDR need not even apply. Things like polarized sunglasses which surely alter our perception of the world. It’s saying, “Oh, you can’t see the highlight and the shadows at the same time? Here, let me change that.” I know, things like this have been happening for centuries.
To me, HDR is trying to improve on the beauty of life as experienced through the human eye and brain. It’s taking an attempt at reality and turning it into a lie. It is taking a literal scene that you enjoy and attempting to skirt around the reality of it that it’s too harshly lit, that it has huge shadows or that the contrast is making things not so pretty. Most of the HDR I have seen passed around the internet as “amazing” is not attempting art. Is it art, if not an accurate representation of what is? I doubt it. Rather, for me, the annoyance comes from attempting to create something that doesn’t exist. I’m not using any examples in this post so as to not focus on any one particular images. Those types of scenes when the human brain looks at the HDR image and screams, “Fake!”. I’m thinking here of cityscapes looking directly into the sun. HDR, when overused, is a grotesque abomination of the reality of life. Experimenting and expanding is good and this is where some of you may find space to call me a hypocrite.īut before you do, hear me out and then I’d actually enjoy hearing your sane, civil, reasoned rebuttal in the comments section below. That has certainly changed over the years as people experiment with new techniques and ideas. Photography, from its roots, has always been an attempt at capturing reality as seen through the eyes of the person behind the camera. The limits of digital photography, currently, keep the images captured within the realm of realistic, lifelike photos. I am not some fundamentalist, purist curmudgeon who despises progress and still does his art with firewood charcoal on a cave wall. I’m going to go out on a limb and state, for the record, I don’t like the overuse of HDR that is touted as examples of good HDR these days.
That can be set the same but to any number between.
If that number is anything other than 255, say 1000, then setting it to 500 will be half power, 250 quarter power etc. So if you change the number on that line (usually it's 255) it can't burn any stronger than that setting. It says Maximum Spindle Speed, but when using a laser instead of a spindle motor it is Laser Power Max. After we pick a fixed width and height, the standard procedure is to resize all the images to this. In LaserGRBL click on the GRBL menu at the top left of main window and click Grbl Configuration. Before we jump to how part, Let us discuss the negative consequence of choosing the wrong size. Just change the number S-MAX 255 in the Target Image settings to match the number stored in GRBL settings $30 and the red box will dissapear. If you set it in GRBL Configuration settings to a lower number than 255 and store it using the Write button at the bottom of the window, Laser GRBL will still show S-MAX 255 in the Target Image settings, but it will put a red box around the number, so you know there is a problem. You can set it to any number inbetween 0 and 255 to adjust the laser power. If you change the S-MAX to 128 it will burn at half power as 255 is maximum power.Ħ4 will burn at a quarter power etc. It's the Laser power minimum and maximum. The PWM setting is the S-MIN and S-MAX setting in the Target Image settings in the image you posted above.
