Destellos realistas con PhotoShop para Arquitectura

October 1, 2019 0 By Peter Engel


good hello again and welcome to this
lesson of the post-production course with photoshop is occasion is I wanted to talk
about a pretty interesting filter are good is an effect that occurs in the
photographic lenses and they are the flashes something kind this is if it could be a little
a flash produced by a source of light as is the sun that is also
it works very well not because they produce in the image in the photograph a kind
of greater realism when effects take place that really good the programs of
rendering do not usually create when we configure the different
light sources however with photoshop it’s very simple, it’s pretty
practical and good fast introducing some kind of flash of this type
where this one carries lens for it we are going to see two procedures one is going to be
using the flash filter itself that includes photoshop and another method is going to
be by applying a photograph or an image that you have has
own flash we’re not going to change the way of
and I have left a bookstore with different flashes within the links
of course download that if you go down this bookshop you will be able to find in
this folder is compressed a set of flashes already configured
perfectly what are these is here You see that we will be able to apply them
within our projects both for spaces that are exterior not by
lighting sources that we have to produce these kinds of effects are a
kind of lights like for projects that be external like the one that was
showing in the example where we are going to can simulate those reflections that are
produce on the surface of our lens if you set these images all
they have a black background so good let’s change the fusion mode of
this layer we will put it in raster mode of this way that fusion mode what’s going
to allow is to spread all the shades that be black in this case this is here
and he’s going to leave that sparkle clean source of light and you will see how it works
very very well therefore let’s see what
how does this system work because the truth is that it’s quite interesting from
use it in photoshop good first thing would be to select some project to
practice I have brought here several images both indoors and this
here that can produce an effect here quite interesting to apply that
flash not in some of the windows as some exterior type examples like
can these be from here it’s worth and we’re going to see how it works how I’m going to
choose for example this image save picture as and I’ll save it in the
image desk we open it with photoshop
right button to open with photoshop would this be from here you know I always
I recommend making a copy of the original layer to have saved by
security and also to see how is the before and after that filter and then
also usually what we do is convert the layer into an object
smart you do not know what goes out is the little symbol that means that the layer
is protected and that we are going to be able apply a filter and make it a filter
smart type that can be edited to posteriori that is quite practical to
the time to work with him later if we had to modify the effect on
flash filter we will find it obviously in the category on the menu
top of filter set here within interpreting a series appear
of filters like this one that we’re going to use today that is the flash agreement of
this one here is very simple it opens a preview window so that preview is
How would that flash look like? you can change the position simply
pressing that little cross and moving moving where I want totally that
occur the light flash set that the program generates as a
of artifacts that are similar to that occur on the surfaces of
the lenses when that source is produced of light as strong as it influences the
camera and the program calculates it directly that’s quite useful the
only good drawback that just we have these four available
lens typologies as I change I will exaggerate a little the size that
You can also control that flash in some kind of stop like
changes not according to the type of lens the type of flash we would have this that is very
classic the 150 300 mm and then these two guys that we have here
this for example if you do not want color as such of the own spark that does not
have no tonality like this one here that is like magenta we could
choose the third type that does not apply no kind of color even this that
we have here is left that kind of more linear artifacts also have
some interest that’s a bit to criterion from each designer who chooses a type
of flash or other I’m going to put this with an intensity a
little bit lower and we see to see how it works we give it to ok as you see fix
has produced that kind of flash that it gives realism to photography
this here if it does not convince us because good to produces an interference with the
project does not finish convincing the effect that it produces we would simply do
double click on the name of the filter that in this case it is flash and we return from
new to the edit window voucher we could modify its position a bit
I think it may look good if it It does not illuminate if it passes between
these two cornices that we have here in the building I think it can work very
ok let’s lower a little bit the intensity I’m even going to put the
third type also personally I like a little more that does not apply light
that if something kind that we have applied as a kind of light source in a
part of the project will change again because it does not convince me and
let’s choose this third one but for example a little here more differentiated
of the building could be something kind this it’s a pretty simple filter I’m going to
choose another example so you can see how it works in this case for example the
inside what we had seen before this that
we have here we are going to save the image As before
and we open it with photoshop labrit with photoshop duplicate the layer with control
j turn into intelligent object and let’s apply here another small
flash is worth so you can see how works
imagine that there is a very light source strong off with that kind of little bit
the first type ok ok it would be this as a very effect
it is clearly marked, but maybe we want to give prominence to
this type of effect that produces even light artifacts here gives us a
little more realism to the scene that we have in particular if I return to space
outside of this here we are going to choose another project for example is this
set of houses save image like and we open it with photoshop in this
case I will use the other method that would be the one to enter a flash has already
previously created and change the mode of merge for that inside the folder in
the batch of flashes we will choose one that we like, for example
good the one that interests us most Depending on the type of project, choose
example this one that I have here we select the file and drag
on top of the work canvas would be this image fix is ​​here to be able
modify the image comfortably what ideal is to have active the option of
show transformation controllers this option here allows us
and the dimension of the flash and so on there’s something kind of this and we’re going to change the
merge mode to a merge mode type plot fix what happens in the mode
fusion plot what it does is that hidden this rule hides those tones that
are darker are blacks and halftones and it will allow us to use the
flash in a much more practical way and position it exactly where
we want for example that light enters some area or that gives a flash in
some crystal or this part of here that is that this can be transformed
perfectly in no problem is can rotate position as more
like and look for a point between vegetation works very well
usually the building lines the resource that works quite well
Double click to confirm and give a little bit more of character to the image this
Obviously you can lower the opacity so that the value of the
flash or even if it has occurred this element that is here I do not see
here a little bit that at the end of the mode the Fusion mode does not stop working
well and it marks a little bit of where it is that source of lighting could
using a layer mask creating a layer mask to this layer here
paint with a black brush in certain size we are going to lower a bit
the opacity of the brush could hide that filter you see that flash in the
edges written not in the limits that do not I want them to appear this is a bit the
effect that we have achieved then is very easy
you have many blocks of this type on the internet the truth I left them
a library with 50 elements but there very many out there and the process is
quite simple is simply enter the flash you want to
your sight not until I have here and change the blending mode to mode
and it works pretty well is simple or be that there is no excuse for not
use this type of resource that I believe that works pretty well
in the projects is a system for put a little lighting a bit
different no more than type the one would produce the lens type flashes
always try to combine with a layer mask and hide using a
brush some areas of the flash that do not they also convince us of the opacity I
I always recommend lowering a little if does not end either to convince the
size must also be adjusted position a little what we talked about
always with the treatment of images through photoshop we have enough
resources and versatility with the program to be able to modify any element
that we introduce in our draft
this is the before and after with some little details of light I think it’s
a very simple resource to use that gives a lot of creative level play each
can create effects that estimate with the theme of illuminating
of this type until here nothing else dismissal see you in the next
lesson of the photoshop course postproduction with photoshop and nothing chao do not good
